摘　　要：基于InVEST模型,利用汉中市2000年、2010年、2020年土地利用与土地覆被数据,气温、降水以及植被归一化指数等基础数据,模拟分析了汉中市碳储量、产水量、生境质量、水质净化以及土壤保持服务的空间动态格局及其权衡协同关系,利用热点分析方法确定各生态系统服务重点功能区域。结果显示,汉中市生境质量整体水平较高,生境质量与碳储量之间一直保持较高程度的协同关系。该结果可为区域生态问题的精准识别以及生态修复重点区域的划定提供参考。Based on the InVEST model,the spatial dynamic pattern of carbon storage,water yield,habitat quality,water purification and soil conservation services in Hanzhong City in 2000,2010 and 2020 were simulated and analyzed by using basic data such as land use and land cover data,temperature,precipitation and vegetation normalization index.The hotspot analysis method was used to determine the key functional regions of ecosystem services.The results showed that the overall level of habitat quality was higher in Hanzhong City,and the synergistic relationship between habitat quality and carbon storage had been maintained to a high degree.The results can provide reference for the accurate identification of regional ecological problems and the delineation of key areas for ecological restoration.
