摘　　要：以湖南省新邵县自然保护地为研究对象,以土地利用、土壤、DEM数据等为切入口,综合运用ArcGIS和InVEST模型,对自然保护地的生态系统服务功能进行了量化分析,并运用Standard Deviation Method对自然保护地的生态系统综合服务功能进行了重要性分级评价。结果表明:①3个保护地的总碳储量为565908.386t,其中,筱溪国家湿地公园的碳储量为65137.73t、白水洞国家地质公园的碳储量为310379.3215t、岳坪峰国家森林公园的碳储量为190391.3369t;水源涵养量空间分布主要表现为“白水洞国家地质公园高、岳坪峰国家森林公园次之、筱溪国家湿地公园低”的趋势;土壤侵蚀量在空间上呈现“白水洞国家地质公园高、筱溪国家湿地公园次之、岳坪峰国家森林公园低”的分布趋势;生境质量高值区主要分布在岳坪峰国家森林公园,总平均生境指数为0.975,低值区主要分布在筱溪国家湿地公园,总平均生境指数为0.904,空间分布差异不显著;②湖南省新邵县自然保护地的生态系统服务功能划分为一般重要区、重要区和极重要区。岳坪峰国家森林公园的重要区占比面积最大,其次为极重要区,一般重要区占比最小。筱溪国家湿地公园的一般重要区、重要区和极重要区的面积占比大致相同。白水洞国家地质公园的重要区面积占比最大,一般重要区与极重要区面积占比大致相等。对保护地的生态系统服务功能进行的研究并对重要性等级进行的划分与评价,可为保护地的可持续发展提供参考。This study takes Xinshao County Nature Reserve in Hunan Province as the research object.Taking land use,soil and DEM data as the cut-off point,ArcGIS and invest model are comprehensively used to quantitatively analyze the ecosystem service functions of the nature reserve,and standard deviation method is used to evaluate the importance of the ecosystem comprehensive service functions of the nature reserve.The results show that:①the total carbon reserves of the three reserves are 565908.386t,including 65137.73t in Xiaoxi National Wetland Park,310379.3215t in Baishuidong National Geological Park and 190391.3369t in Yuepingfeng National Forest Park;The spatial distribution of water conservation mainly shows the trend of"Baishuidong National Geopark is high;Yuepingfeng National Forest Park is second,and Xiaoxi National Wetland Park is low";The spatial distribution trend of soil erosion is"Baishuidong National Geopark is high;Xiaoxi National Wetland Park is second and Yuepingfeng National Forest Park is low";The high value areas of habitat quality are mainly distributed in Yuepingfeng National Forest Park,with a total average habitat index of 0.975,and the low value areas are mainly distributed in Xiaoxi National Wetland Park,with a total average habitat index of 0.904 and no significant differences in spatial distribution;②The ecosystem service function of Xinshao Nature Reserve in Hunan Province is divided into general important areas,important areas and extremely important areas.Yuepingfeng National Forest Park has the largest proportion of important areas,followed by extremely important areas and the smallest proportion of general important areas.The area proportion of general important areas,important areas and extremely important areas of Xiaoxi National Wetland Park is roughly the same.Baishuidong National Geopark has the largest proportion of important areas,and the proportion of general important areas and extremely important areas is roughly the same.The research on the ecosystem service functions of the
