摘　　要：自然保护区是生态建设的核心载体,在维护国家生态安全中居于重要地位。采用当量因子法计算四川全省和省内75个高等级自然保护区内2000年、2010年、2020年的生态系统服务功能价值(ESV),并结合基于强度分析框架构建的土地利用/覆盖变化强度图谱分析自然保护区内土地利用格局时空变化情况,根据ESV和土地利用的时空变化共同对四川省自然保护区生态服务功能建设成效进行评价。研究表明:(1)四川省自然保护区生态功能建设成效显著,自2000年以来ESV持续上升,到2020年总ESV高达1757亿元。(2)四川省自然保护区生态功能建设成效具有明显的空间异质性,高ESV自然保护区主要集中在四川中部地区,如贡嘎山、若尔盖湿地自然保护区2020年的ESV分别高达215亿、175亿元。(3)在20年的保护与建设中,四川省自然保护区土地利用结构与人地关系逐步得到优化,为生态环境建设奠定了良好基础。Nature reserve is the core carrier of ecological construction and plays an important role in maintaining national ecological security.In this paper,the equivalent factor method is employed to calculate the ecosystem service value(ESV)in Sichuan province and its 75 high-grade nature reserves in 2000,2010 and 2020,and the land use/cover change intensity map based on the intensity analysis framework is used to analyze the spatial-temporal variation of land use pattern in nature reserves.According to both ESV and the spatial-temporal variation of land use,the effectiveness of ecological service function construction in nature reserves of Sichuan province was evaluated.The research show as follows:(1)The ecological function construction of nature reserves in Sichuan province has achieved remarkable results;ESV has continued to rise since 2000,with the total ESV reaching 175.7 billion yuan by 2020.(2)The effectiveness of ecological function construction of nature reserves in Sichuan province has obvious spatial heterogeneity;the nature reserves of high ESV are mainly concentrated in the central part of Sichuan province;for example,the ESV of Gongga Mountain and Ruoergai Wetland Nature Reserve in 2020 reached 21.5 billion and 17.5 billion yuan respectively.(3)Over the past 20 years of protection and construction,the land use structure and man-land relationship of nature reserves in Sichuan province have been gradually optimized,which has laid a good foundation for the construction of ecological environment.
