江苏里下河地区"三生"空间格局演变及优化策略
Evolution and Optimization Strategy of Production-Living-Ecological Space in Lixiahe Area of Jiangsu Province
摘要
Abstract
Based on the land use data of eight periods in Lixiahe area from 1985 to 2020,this paper explores the evolution and driving force of the production-living-ecological space pattern.Using ESV,InVEST and other models,a number of ecological factors were considered to explore the impact of spatial pattern evolution on ecosystem services in the Lixiahe area.The PLUS model and the geographically weighted regression model were used to synergistically optimize the production-living-ecological spatial pattern under different objectives.The results showed that:(1)During 1985～2020,the area of production,living and ecological space in Lixiahe area increased by-14.7%,245.2%and 296.5%.The main transfer methods are production to life,production to ecology,and the increase of living to production and ecological to production after 2010.(2)During 1985～2020,the evaluation score of comprehensive ecosystem services in the Lixiahe area decreased year by year,and the average score decreased from 0.40164 in 1985 to 0.37963 in 2020.Among them,the total score of production space decreased by 16.1%,the total score of living space increased by 221.5%,and the total score of ecological space increased by 209.1%.(3)The optimization results showed that under the goal of ecosystem service value,the value of ecosystem services increased by 67.59%,and the score of comprehensive ecosystem services increased by 0.44%.Under the goal of ecological security pattern,the score of habitat quality increased by 2.07%,and the score of comprehensive ecosystem service increased by 0.14%.Under the"dual carbon vision",carbon storage increased by 0.31%,and the score of comprehensive ecosystem services increased by 0.79%.关键词
