Fractional vegetation coverage (FVC) is an important parameter of regional ecological environment quality. Taking Tianjin Binhai International Airport as the research center, Dongli District and Hedong District are selected as the research area, based on the Landsat remote sensing images from 2000 to 2019, and combined with the pixel dichotomy model to calculate FVC. Using linear regression and F-test to analyze the temporal and spatial evolution trend of FVC, using the coefficient of variation to analyze the fluctuation of FVC, the geographic detector model is used to explore the climatic factors (annual average temperature, annual precipitation), economic factors (population density, GDP) and human activity factors (take-off and landing sorties and passenger flow) to explain the strength of FVC. The result shows that the annual average FVC in the study area shows a downward trend as a whole from 2000 to 2019, and there were differences in the changing trends of different grades of FVC. The FVC in the study area fluctuates stably as a whole, and the vegetation coverage of Tianjin Binhai International Airport is low and the stability is poor. There are significant differences in the explanatory power of each influencing factor for FVC in the study area. The research results are of great significance to the environmental protection of airports and the sustainable development of airports.

“…Factor detection is used to detect the spatial differentiation of the dependent variable Y (FVC value), and to detect the influence of the independent variable X (each natural factor and artificial factor) on the spatial differentiation of Y, which is measured by the q value. [10] The q value can be calculated by formula (7):…”

“…It can be presumed that each successive transformation of land by humans exacerbates environmental imbalances [2,3]. The development mode in the past has caused many environmental problems, spatially manifested by the encroachment of living or production spaces into natural spaces [4], with the temporal trend of landscape fragmentation, woodland degradation, and a decline in habitat quality [5][6][7]. The disorderly exploitation of natural spaces not only restricts sustainable economic development [8,9], but also causes serious negative effects on people's health [7,10].…”

The ecological restoration of territorial space emphasizes the synergy between ecology and social development. On this basis, we used landscape index analysis methods to explore the spatiotemporal evolution of landscape patterns in urban areas on a district scale. Then, we used multiple regression analysis to explore the driving factors behind this evolution. The results showed the following: (1) Landscape compositions have changed significantly. The growth rate of construction land in the main districts was about three times that in the urban area. (2) There were differences in the characteristics of landscape pattern evolution. Arable land is becoming more fragmented as construction land expands outward. The shapes of public green spaces, arable land, and woodlands tend to be simple and regular. The degree of both urban sprawl and agglomeration decreased in the urban area and the main districts. Meanwhile, landscape separation first decreased and then increased, and landscape diversity increased. (3) Population growth, industrial development, changes in industrial structure, and real estate development are the main driving factors of landscape pattern evolution. Based on this, this study puts forward some suggestions for landscape pattern optimization, which is significant for ecological restoration planning and promotion.
