摘　　要：以荆州市为研究区域,利用荆州市2021年相关数据计算和分析了荆州市生态系统服务价值(ESV)和生态系统服务稀缺价值(ESSV)指标,并运用地理信息图谱、景观格局指数、冷热点分析法、供给和需求弹性指数等方法评估和揭示ESV和ESSV的时空异质性变化及其原因和机制。结果表明,土地利用变化主要集中于耕地转变为林地或草地,未利用地转变为水域或其他类型,林地或草地转变为建设用地。各类型土地的多样性和均衡性均提高,山水林田湖草沙一体化保护和修复工程(SLCP)的综合治理和协调发展等措施的效果取得一定成效。ESSV在空间上呈现出由东部向西部递增的分布特征,且在空间上呈现出明显的聚集特征。Taking Jingzhou City as the research area,the ecosystem service value(ESV)and ecosystem service scarcity value(ESSV)indicators were calculated and analyzed using relevant data from Jingzhou City in 2021.Methods such as geographic information graph,landscape pattern 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(SLCP)had achieved certain results.ESSV showed an increasing distribution pattern from east to west in space,and exhibited obvious clustering characteristics in space.
