喀斯特生态脆弱区"三生"空间时空演变与功能优化
The Spatiotemporal Evolution and Functional Optimization of Productive-living-ecological Space in Karst Ecologically Fragile Areas
摘要
Abstract
Based on the remote sensing monitoring data of land use in Shilin Yi Autonomous County in 2010,2015 and 2020,the spatial and temporal evolution characteristics of productive-living-ecological in Shilin Yi Autonomous County are analyzed by means of dynamic degree,transfer matrix and land-scape pattern index,and optimization strategies are put forward.The results show that(1)the ecologi-cal space accounts for the main part of the productive-living-ecological space in Shilin Yi Autonomous County,and the proportion of productive and ecological space is small.The living space is concentrated in the western urban area of Shilin Yi Autonomous County and the surrounding market towns.The productive space is distributed around the living space,and the rest areas are ecological space.(2)From 2010 to 2020,the dynamic degree of land use in Shilin Yi Autonomous County's productive-living-eco-logical space showed an upward trend,with a large increase of 3.6%from 2015 to 2020.(3)The pro-ductive-living-ecological space in Shilin Yi Autonomous County shows an evolutionary trend of"pro-duction+life+ecology-",which means that the production and living space increase while the ecolog-ical space decreases.(4)From 2010 to 2020,the level of surface fragmentation in Shilin Yi Autonomous County's productive-living-ecological space was always high,and the surface landscape was gradually diversified.Moreover,the land dynamic transfer was gradually intense,and the ecological space was gradually occupied,and the ecological vulnerability was further increased.关键词
