Research Article Surrounding Environment and Civil Airport Fire Emergency Management Based on Big Data Simulation

The new generation of information and communication technologies represented by the Internet of Things, big data, and cloud computing are developing rapidly. Through continuous integration with other emerging technologies, the Internet of Things technology accelerates its penetration into the fields of smart medicine, new energy, and materials. In this article, we will explore the airport peripheral environment and civil airport fire emergency management. In airport emergency management, bird strike and fire management are the most frequent problems. Bird strikes most often occur in aircraft take-off, taxi, and landing areas. Therefore, the study of airport environmental characteristics is particularly important. In order to improve the emergency support capability of the civil airport fire department and the level of airport operation support, it is necessary to clarify the factors that affect the emergency support capability of the airport fire department. This article is based on the research of the airport surrounding environment of Big Data Internet of Things and applies it to the research of civil airport fire emergency management, which improves the emergency ability of airport firefighters.


Introduction
"Big data" has become a buzzword in today's production and people's lives. Everywhere, such as mobile communication, website access, microblog news, video uploading, product generation, and scienti c experiments, social and commercial activities will continue to generate various types of data [1]. e research value of big data is huge, especially when big data is integrated into today's Internet of ings, the integration of big data and the Internet of ings will surely elevate the intelligence of human society to a new level, and its development prospects are unlimited [2]. Nowadays, the Internet of ings is widely popularized, and the amount of big data has increased sharply. e integration of the Internet of ings and big data has become an inevitable trend in the development of various disciplines [3]. In this article, we will explore how big data a ects the Internet of ings and how it integrates with daily production and life applications [4]. "Bird strike" is the abbreviation for safety accidents caused by planes colliding with birds during take-o , landing, or ight. It is also called "bird strike." Today, there are more than 10,000 bird strikes in the world every year, and the International Aviation Federation has upgraded bird strike disasters to category "A" aviation disasters. is article examines more than 30 existing ights in large civil airports [5]. First, it studies the environmental characteristics of the airport. e climate in the airport is suitable and the bird resources are relatively abundant [6]. erefore, the bird community structure and environmental structure of the airport and its surrounding areas are studied. It is very necessary to conduct research. It is necessary to analyze the factors that may cause bird strikes in the airport and its nearby areas through the research results, nd out corresponding preventive measures, and improve the ight safety factor of the airport [7]. According to the statistics of the International Civil Aviation Organization, the number of aircraft accidents during the take-o , taxiing, and landing phases accounted for more than 60% of the total number of aviation accidents [8]. In the above stages, the emergency response task of aircraft emergencies is mainly undertaken by the airport re rescue department, and the emergency protection ability of airport re ghters is the key to ensuring the smooth implementation of rescue activities [9,10]. e results show that the most important impact on civil airport fire emergency management capabilities is the basic quality, followed by the professional quality, professional skills, and professional knowledge of firefighters. By attaching importance to these factors, our fire management capabilities will be improved [11,12].

Overview of the Study Area.
e research airport is 45 km away from the city. e traffic around the airport is developed. ere is National Highway 2513 on the north side, connecting neighboring provinces and surrounding areas; on the east side, there is Provincial Highway 324, connecting the surrounding districts and cities; in front of the gate is 104 National Road, connecting the urban area and certain areas. As a large-scale civil airport, the airport is also the central airport of the economic zone. It can radiate air travel for the surrounding population of 100 km, including 20 prefecturelevel cities, with a radiating population of 120 million. e research airport has an important influence on the economic development of the surrounding area. e airport covers an area of about 3800 mu, and it can transport up to 1 million passengers every year.
Most of the east side of the airport is a residential area. ere are no farms in the village. e farmland is mainly planted with seasonal crops. ere are several small forests scattered around the village. ere is a lotus pond in the northeast corner with sufficient water resources and less vegetation. Close to the airport is the provincial highway and the abandoned Yellow River. e abandoned Yellow River is located in the east of the airport. e flow direction of the river section within the observation range is a U-shaped turning from northwest to southeast to southwest to northeast. e closest distance to the easternmost part of the airport is about 300 m, within the observation range. e widest part of the river is about 100 m. e riverbank is flat and the vegetation is lush, mainly cherry trees, willow trees, neem trees, and various weeds. ere are no duck and goose farms in the observation area of the river.
Most of the airport fence is farmland and woods during the week, and most of the farmland is planted with seasonal crops. ere is a forest close to the north and west of the airport fence, with an area of about 0.027 km 2 , and the main tree species is poplar. ere is a small river running northsouth beside the forest, with a width of about 20 m. ere is an airport drain in the middle of the north side of the fence. e sanitary conditions are poor and there is no cover. It is easy to breed mosquitoes and attract birds to forage. ere is a nursery near the middle on the north side of the fence, which is roughly east-west and covers an area of about 0.253 km 2 . e nursery mainly contains many kinds and numbers of plants, which provides a place for birds to forage and hide. ere is a vegetable greenhouse on the east side of the nursery, which is enclosed. To the east of the north side of the fence is an orchard, covering an area of about 0.027 km 2 . It is mainly planted with pear trees. Due to manual management, there are fewer weeds in the orchard. e expansion and construction in the southeast and southwest affected bird activities and brought some impact to the investigation. e airport consists of a passenger waiting hall, an internal flight area, and an office area. e concrete pavement in the flight area of the airport has runways, taxiways, connection roads, patrol roads, etc., and the rest are lawns. e flight area is east-west, with a total length of 3600 m, and the light belts on the east and west sides are local dominant grass species.
e flight area is dominated by lawns. e lawn vegetation composition is basically the local dominant grass species. Two rows of east-west bird blocking nets are arranged on the north side of the lawn near the fence. e bird blocking nets are parallel to the fence and perpendicular to the ground. e bird blocking nets are 3000 m in length, the height is 5 m, and the mesh size is 40 cm 2 . e grass species in the lawn are mainly local dominant grass species with many species, and more insects in summer. e grass height in the lawn is basically kept below 20 cm, and the airport regularly organizes the spraying of pesticides on the lawn, including pesticides and herbicides. ere are exposed drainage ditches near the fence in the north of the lawn, and the internal drainage ditches are all dark water ditches, which facilitate the drainage of the accumulated water in the flight area to the airport, and are covered by a linear drainage cover. e office area in the airport has a large green area and rich vegetation.

Research Methods.
e Internet of ings is known as the third wave of development in the global information industry after computers and the Internet [13]. e International Telecommunication Union formally expounded the concept of the Internet of ings in its report. Any object in the Internet of ings exchanges information and communication anytime and anywhere to truly create a network of precise positioning, precise identification, and intelligent monitoring and management [14,15]. e development of the Internet of ings is based on the expansion and extension of the Internet, and the ultimate development goal is comprehensive perception, reliable transmission, and intelligent processing [16]. Among them, the network layer is the link of information exchange between the perception layer and the application layer.
rough the processing and exchange of sensor information, the application layer provides powerful resource support for the processing of different enterprises and truly realizes the intelligence and informatization of different industries. From July 2019 to June 2020, the transect method was used to collect statistics on birds and environmental changes in different seasons within an average of 5 km around Guanyin airport and its surrounding areas. e survey frequency was twice a month. e observed environmental factors include seasonal environmental factors, such as the types and growth status of crops in farmland, the area occupied, the vegetation composition, and change patterns of grassland and woodland; there are also factors that do not change with the seasons, such as rivers, ponds, and residential areas. Environmental factors are mainly measured and recorded, combined with interview methods.

Results
A total of 75 species of birds in 14 orders, 35 families, and 14 orders were found in the first anniversary of the airport from July 2019 to June 2020. ere are 39 species in 19 families of Passeriformes, 52% of the total number of species, ranking first in the number of species; 3 families and 7 species of Platymoides, accounting for about 9.33% of the total number of species, ranking second in number of species; Gruciformes: there are 5 species in 1 family, and the number of species accounts for about 6.67% of the total, ranking third; the number of species of the remaining 11 orders is less than 5 species. See Figure 1 for the ratio of the number of different mesh types. e airport is located in the southeastern part of the North China Plain. e number of resident birds is the largest, with 26 species, accounting for about 35% of the total; summer migratory birds are second, with 24 species, accounting for 32% of the total; and the third, 17 species of migratory birds, accounting for about 23% of the total; winter migratory birds are the least, 8 species, accounting for about 10% of the total. Resident birds and summer migratory birds are an important part of the birds around Guanyin Airport. Breeding birds accounted for 67% of the total number of species, and nonbreeding birds accounted for 33% of the total number of species (see Figure 2). e types and proportions of 75 species of birds around the airport are shown in Figure 3.
According to the relative importance value, there are 11 species of most important birds, accounting for 15% of the total number of species; 10 species of important birds, accounting for 13% of the total number of species; 22 species of less important birds, accounting for the 29% of the total number of species; 32 species of least important birds,  e details are shown in Figure 4: Calculating the comprehensive risk of bird strikes for the birds in the airport fence shows that there are as many as 6 species of birds with R > 0.7. In this survey of the airport and its surrounding areas, a total of 75 species of birds were recorded. rough calculations, the relevant indices of bird community structure in each season were calculated and analyzed. See Table 1 for details. e diversity index of the bird community in spring and autumn is high, the homogeneity index is high, and the degree of dominance is low. e community structure in spring and autumn is relatively stable, and the individual distribution among species is relatively even. Because it is an airport, the status of dominant species cannot be determined. e scale of bird migration in this area is not large, and the impact on the local bird community structure is small. Comparing spring and autumn, the community diversity index in spring was higher than that in autumn, and the community structure in spring was more stable than that in autumn. It is speculated that part of the reason is that there are more migratory birds in autumn than in spring. According to statistics, 8 species of migratory birds can be observed in spring, accounting for 2.5% of the total in spring.
ere are 14 species of migratory birds observed in autumn, accounting for 3.6% of autumn. e number of migratory birds observed in spring is lower than that in autumn. Among migratory birds, this is consistent with the observed results. In summer and winter, the diversity index is low, the homogeneity index is low, and the dominance index is high, indicating that the social structure is relatively unstable in summer and winter, and the dominant species are obvious. If we compare the diversity index of summer and winter communities, we can see that the diversity index in winter is higher than that in summer, and the community structure in winter is more stable than in summer; in winter, the number of species and birds decreases, and the distribution of individuals among different species is more even.
In the seven habitats divided by the airport, the diversity index is arranged from largest to smallest: nursery, water area, farmland, woodland, grassland, breeding area, and residential area. See Table 2 for the relevant indices of the community structure of each habitat. e nursery structure is more complex, including trees and low shrubs. Most birds build nests on trees. Trees provide a habitat for birds, low shrubs provide a shelter for birds, and there are also seed-bearing weeds, which provide a food source for birds. e main plants in the nursery are ginkgo, eucommia, rose, cocklebur, bermudagrass, Imperata cylindrica, and other vines. In addition, there is sufficient water in the nursery to provide a water source for the survival of birds. e structural levels of this area are relatively rich, and the vegetation at different heights meets the habitat and survival requirements of different birds. erefore, the nursery habitat is the most stable habitat type among the 7 habitats in Guanyin Airport and its surrounding areas.
e dominant species of birds in each plot are shown in Table 3. e composition of birds in different areas has a certain similarity. Among them, the similarity coefficient of plot 1 and plot 4 is the highest, and there are 34 common species; the similarity coefficient of plot 1 and plot 5 is the lowest, with 19 common species, as shown in Table 4.
Airport birds have different daily activity rhythms in different seasons, as shown in Figure 5.
ere are significant differences in the daily activity frequency of birds in summer, as shown in Figure 6.

Analysis of Influencing Factors of Civil Airport Fire
Emergency. According to the basic rules of the airport fire department, the competency requirements of some airport firefighters were analyzed in detail. In the case of emergency aircraft rescue, firefighters must not only extinguish the affected aircraft but also provide basic medical assistance to the wounded, and use the knowledge of the fire brigade's emergency response capabilities in other areas. e multiple interactions between the commander and the airport firefighter finally determine the main factors that affect the firefighter's airport emergency response capability.
In recent years, the incidence and losses of fires in China have been increasing year by year, and the problem of a small number of firefighters and insufficient firefighters skills in China has gradually emerged. Overall, there is still a big gap between the number of firefighters in China and industrialized countries. Due to the lack of active firefighters, it is very necessary to organize full-time firefighters in areas far away from many professional companies and the Chinese fire department, especially in key locations such as airports. Full-time firefighters not only have the opportunity to extinguish the first fire of the unit, but can also provide superregional support and excellent protection for fire rescue. e same full-time firefighter also has many shortcomings, such as the vitality and combat effectiveness of the team is severely limited, unable to meet the requirements of large-scale fire rescue.
With the continuous development of China's economy and the issuance of national policies, China's trade exchanges with other countries have become more and more frequent. Civil aviation has also developed rapidly due to its large transportation volume and fast transportation speed. e importance of the fire brigade, which is an important part of the airport's safe operation, has gradually become prominent, and it has received more and more attention from the Civil Aviation Administration, airlines, and    airports. erefore, the ability of airport firefighters is also a great challenge, and how to improve the emergency support ability of airport firefighters is also the focus of all aspects.

Fire Emergency Management Strategy for Civil
Airports. e improper allocation of emergency resources in small and medium airports is not caused by unilateral dereliction of duty by the airport management department. is includes improper government regulations and improper airport resettlement. erefore, to solve the problem of insufficient allocation of emergency resources in small and medium airports, the joint efforts of civil aviation management departments, local governments, and airports are still required.
Regulations and standards must conform to China's national conditions. If the highest-level aircraft at the airport has less than 700 take-offs and landings in the busiest three months, the fire and emergency protection level of the highest-level aircraft can be reduced by up to one level. No matter how big the airport is, whether it is crowded or not, aviation accidents will happen, but the possibility of occurrence is very small or unlikely; aircraft accidents happen on the same type of aircraft, regardless of the size of the airport, whether it is congested or not, in terms of emergency response time and handling methods no difference. erefore, it is not appropriate to use airport congestion as compensation for fire safety and emergency rescue protection levels but to consider the response time and protection capabilities of airport fire protection and emergency rescue services as compensation.
Utilize the resources of the airport premises. For small and medium airports in operation, it is recommended to sign an airport rescue contract or local emergency rescue plan, and clarify the responsibilities and obligations of local government agencies, companies, and unit camps in accordance with relevant regulations. Utilize emergency resources from ministries, enterprises, and local government camps to reduce or exempt emergency resource allocation that can be provided by local government agreements and emergency rescue plans, reduce insufficient small-scale resource allocation, reduce resource allocation pressure, avoid resource duplication, and eliminate energy waste. Improve the airport rescue system. e airport undertakes the main task of emergency rescue, improves the emergency rescue plan, clarifies the responsibilities and obligations of all parties, and actively allocates emergency resources to various local government agencies, enterprises, and institutions. In terms of emergency resource allocation, emergency training and education, local government departments, and enterprise troops should provide maximum support to comprehensively improve the comprehensive emergency rescue level of airport rescue personnel and minimize property losses.

Conclusion
e current era is an information era, and big data is the key word of this era. rough the integration of big data and the Internet of ings, human society has reached an unprecedented level of intelligence, which has brought unprecedented convenience to people's production and lives. At the same time, it briefly introduces the integration, management, and technical framework in data processing. China is rich in bird resources and poses a great threat to flight safety. With the emphasis on the ecological environment in recent years, we must pay attention to the impact on the ecological environment while carrying out bird strikes. How to balance bird strike prevention and protection of the ecological environment has become an important difficulty. After sorting out the data from the airport, this paper uses various analysis methods to effectively analyze the community structure in each season and habitat. China has not yet established target standards for the training and skill assessment of airport firefighters, and cannot effectively control some aircraft emergencies in a timely and effective manner. erefore, analyzing the factors that affect the emergency response capability of the airport fire brigade and determining the degree of influence of each factor is of great significance for improving the airport's operational security level.
