摘　　要：【目的】定量分析长江中游流域国家级自然保护地交叉重叠特征及其优化整合对策,为我国自然保护地的合理规划与布局提供科学依据。【方法】以长江中游流域6类661处国家级自然保护地为研究对象,运用ArcGIS核密度指数方法,定量分析其交叉重叠特征和优化整合对策。【结果】长江中游流域共214处国家级自然保护地存在交叉重叠,主要集聚分布于鄱阳环湖、大别山南部武陵山脉和伏牛山等区域;在省级行政区划交界、流域区划交界、生物多样性保护优先区和生态功能保护区内,优化整合应优先考虑以国家公园、自然保护区、风景名胜区和自然公园4类为主体分别进行类型整合、范围调整、吸收合并和同类合并。【结论】运用ArcGIS定量可视化叠加分析方法,可以有效识别并判断自然保护地交叉重叠现状、特征及问题,有利于科学构建我国自然保护地体系及其空间格局规划。【Objective】 The aim of this study is to conduct a quantitative analysis of the overlapping characteristics ofnational natural protected areas in the middle Yangtze River basin and their optimization and integration strategies. Thiscould provide a scientific basis for rational planning and layout of natural protected areas in China. 【Method】The 661 national natural protected areas in the middle Yangtze River basin were classified into six types and used as the researchobject. This study quantitatively revealed their overlapping characteristics and optimized integration strategies by usingthe ArcGIS nearest neighbor index and nuclear density index. 【 Result】 We found 214 overlapping national naturalprotected areas in the middle Yangtze River basin, mainly concentrated in the Poyang Lake, South of the DabieMountains Wuling Mountains and Funiu Mountains, as well as provincial administrative divisions, river basin divisions,biodiversity conservation priority areas, and ecological function protection areas. Priority should be given to the aboveareas for optimization and integration and type integration. Moreover, similar mergers, absorption mergers, and scopeadjustments should be carried out with national parks, nature reserves, scenic spots, and natural parks as goals.【Conclusion】Using the ArcGIS quantitative visualization overlay analysis method, the problem of overlapping of naturalprotected areas can be effectively solved, which is conducive to the scientific construction of a country’s nature reservesystem and its spatial pattern planning.
