Spatial—temporal evolution of land use changes and ecological risks in the ecological conservation area:taking Huairou district of Beijing as an example
As an important ecological barrier in the capital,the ecological conservation area increases the probability of ecological risk with the development of urbanization.This paper takes Huairou district,Beijing,as the research area and uses data from 2000,2010,and 2020 to analyze the land use change in the ecological conservation area and evaluate its ecological risk by employing methods such as land use transfer matrix,landscape pattern index,semivariogram,and spatial autocorrelation analysis.The results show that,influenced by the stage of urban development,the land use change in Huairou district was more intense from 2010 to 2020 than that from 2000 to 2010,with the main changes being the conversion between forest and grassland and the one-way transfer from arable land to construction land.During the study period,Huairou district effectively balanced the relationship between protection and development,gradually improving the overall ecological risk with the ecological risk index showing a decreasing trend.Low-risk areas in the plain region showed agglomerative growth,while high-risk areas in the mountainous and valley regions decreased annually.The research results provide valuable experience and inspiration for exploring green and sustainable development in ecological conservation areas.
