基于GIS的淳安县"三生空间"格局演变及其驱动力分析OA

Studying the evolution of the"production-living-ecological space"pattern and its driving factors is of great signifi-cance for promoting regional coordinated development,advancing rural revitalization,and achieving sustainable develop-ment.This paper used ArcGIS to construct a"production-living-ecological space"transition matrix model,combined with landscape pattern indices,to analyze the spatial heterogeneity and evolution characteristics of the"production-living-ecological space".Additionally,the geographic detector model was employed to reveal the driving factors of the changes in the area of the"production-living-ecological space".The results show that the largest change in the"production-living-ecological space"area occurred between 2010 and 2015.From 2005 to 2020,the area transitions in Chun'an County were primarily between production space and ecological space.The landscape fragmentation and degree of disturbance of the"production-living-ecological space"in Chun'an County continued to decrease,while its complexity increased.The natural-ness of the ecological space continued to recover,the control ability of dominant patches weakened,landscape heterogeneity decreased,and landscape evenness improved.Socioeconomic factors were the dominant drivers of the changes in the"production-living-ecological space"area in Chun'an County,while the natural environment served as an important driving force and a fundamental limiting condition.The research results provide valuable references for territorial spatial planning in Chun'an County.
