Green space and ecological environment quality change in Beijing shallow mountain area
As an important ecological source and ecological barrier in the capital,Beijing's shallow mountain area bears the task of driving the economic development of mountain areas and the sustainable development of the city.Studying the green space structure of Beijing's shallow mountain area can provide references for promoting greening construction in the area,thereby improving the ecological environment quality of the shallow mountain area.This study takes Beijing's shallow mountain area as the research area,extracts the green space in Beijing's shallow mountain area from 2015 to 2021 based on object-oriented classification methods,analyzes its distribution and change characteristics,and explores the improvement effect of green space changes on soil erosion and its impact on ecological environment quality.The results show that the green space area in Beijing's shallow mountain area has generally increased from 2015 to 2021,with an increase of 8.00%and a total increase of 30,867.39 hectares.The soil erosion in Beijing's shallow mountain area has improved significantly from 2015 to 2021,and the increase in green space area has made a greater contribution to the improvement of soil erosion.The increase in green space area in Beijing's shallow mountain area from 2015 to 2021 has made the ecological environment quality of the shallow mountain area in 2021 generally better,with an increase of 63,877.19 hectares in the area with good ecological environment quality evaluation grade.The ecological environment quality of Beijing's shallow mountain area in 2021 is much higher than that in 2015.
