"三生"空间优化视角下四川凉山生态脆弱区国土空间格局研究
Exploring the territorial spatial patterns in Liangshan's ecologically fragile mountainous areas with a focus on optimizing Production-Living-Ecology space
摘要
Abstract
The Liangshan Yi ethnic region of Sichuan is a typical mountainous ecological fragile area in western China,and the optimization of the spatial pattern of production-living-ecology space(PLES)under the context of territorial spatial planning is of great theoretical and practical significance.Based on five periods of land use data from 1980 to 2020,this study analyzed the evolution of land use spatial pattern by using transfer matrix and landscape pattern index,and revealed the driving mechanism by using Geo-detector.The results showed that:(1)the spatial structure of land in Liangshan region of Sichuan was dominated by ecological space,followed by production space.Among them,forest and grassland ecological space were the main types.(2)The interconversion between forest,grassland ecological space and agricultural production space was the main types of the evolution of the PLES in Liangshan region.(3)From the perspective of temporal change,the landscape pattern index of the PLES in Liangshan region did not change significantly in the time dimension,but the difference in spatial distribution was obvious.(4)Distance from the town center,mean annual air temperature,elevation,and geological disaster density were the main factors affecting the evolution of the spatial pattern of the PLES.Moreover,the explanatory power of the interactions of factors in each period was greater than a single factor,showing two-factor enhancement or nonlinear enhancement.The study provides a reference for the optimization of the spatial pattern of land use and land cover in mountainous ecologically fragile areas under the context of territorial spatial planning.关键词
