Pattern Evolution and Driving Factors of Production-Living-Ecological Space in Dongting Lake Eco-economic Zone
Studying the evolution of PLE(production-living-ecological)spatial pattern and its driving factors in the Dongting Lake Eco-economic Zone can not only reveal the temporal and spatial evolution of the land spatial pattern,but also provide a theoretical basis for optimizing the regional land spatial structure.Based on the data of land use types,natural environment and socio-economic data of Dongting Lake Eco-economic Zone from 1990 to 2020,The spatial pattern evolution and driving factors of PLE space(production-liv-ing-ecological space)in Dongting Lake Ecological Economic Zone from 1990 to 2020 were analyzed by using ArcGIS spatial analysis,dynamic degree of PLE Space,transfer matrix of PLE Space and geographical detector.The results show that from 1990 to 2020,the PLE Space in Dongting Lake Eco-economic Zone is mainly based on production and ecological space,showing a trend of increasing liv-ing and ecological space while decreasing production space.From 1990 to 2020,the Dongting Lake Eco-economic Zone is dominated by the mutual transformation of production and ecological space,followed by the transformation between production and living space,and the mutual transformation between living and ecological space is the least.From the perspective of the dynamic degree of the com-prehensive PLE Space in the districts and counties,the high and higher values of the dynamic degree of the districts and counties from 1990 to 2020 are mainly located in the northern part of the study area,the middle equivalent and lower value areas are mainly located in the middle of the study area,and the low value areas are mainly located in the eastern and western parts of the study area.Slope,elevation,annual average temperature,soil type,distance from river system,spatial distribution of population and distance from urban center are the main influencing factors of the evolution of PLE Space in Dongting Lake Eco-economic Zone,the interaction of the main factors is double factor enhancement.The research is expected to provide support for coordinating regional Production-Living-Ecological Space conflicts and provide reference for the Land space planning of the Dongting Lake Eco-economic Zone.
