Effects of Integrated Protection and Restoration Projects of Mountain,Water,Forest,Farmland,Lake,Grass and Sand on Ecosystem Service Value and Scarcity Value in Jingzhou City
Taking Jingzhou City as the research area,the ecosystem service value(ESV) and ecosystem service scarcity value(ESSV) indica-tors were calculated and analyzed using relevant data from Jingzhou City in 2021.Methods such as geographic information graph,landscape pat-tern index,cold and hot spot analysis,supply and demand elasticity index were used to evaluate and reveal the spatiotemporal heterogeneity changes of ESV and ESSV,as well as their causes and mechanisms. The results showed that land use change was mainly concentrated in the conversion of cultivated land into forest or grassland,the conversion of unused land into water bodies or other types,and the conversion of forest or grassland into construction land.The diversity and balance of various types of land had been improved,and the comprehensive management and coordinated development of the integrated protection and restoration project of mountains,rivers,forests,fields,lakes,grass and sand( SL-CP) had achieved certain results.ESSV showed an increasing distribution pattern from east to west in space,and exhibited obvious clustering characteristics in space.
