Abstract
Exploring the landscape ecological risk evolution characteristics and driving forces of mountainous cities under the rapid urbanization context can play an important role in protecting and maintaining the stability of the ecological system.Based on geographic information system(GIS)technology,this study used landscape transfer matrix,landscape ecological risk assessment model,and grey relational model to conduct an in-depth analysis of the landscape ecological risk evolution and driving forces in Miyi County from the perspective of landscape pattern.The study shows that the land use structure of Miyi County has undergone significant changes over the past 10 years.The landscape ecological risk exhibits spatial heterogeneity,with high-risk areas primarily concentrated in water wetlands and cultivated land regions.Overall,the ecological risk trend shows a transition from high to low,reflecting the positive effects of ecological protection and restoration.Among the socioeconomic factors,per capita disposable income has a significant impact on landscape ecological risk.Natural environmental factors such as elevation,vegetation index,and precipitation also play an important role in the variation of risk values.The interaction of these factors jointly determines the level and distribution of landscape ecological risk in Miyi County.The results of this study can provide a reference for land use planning and management in Miyi County,optimizing land use structure,and formulating reasonable protection strategies.关键词
