摘要: 对自然保护地空间分布格局和空间重叠关系进行研究是构建以国家公园为主体的自然保护地体系的重要基础。以湖南省9种类型582处自然保护地为研究对象,采用地理集中指数、ArcGIS空间分析技术对湖南省自然保护地空间分布和重叠特征进行分析,并提出整合优化对策。结果表明,湖南省自然保护地呈集中分布格局,其中,武陵-雪峰山地、南岭山地自然保护地数量占全省保护地数量的61.41%,是自然保护地分布密集的地理生态区。湘西土家族苗族自治州、怀化市、邵阳市和永州市是自然保护地数量较多的行政区。自然保护地交叉重叠现象突出,重叠自然保护地数量占全省自然保护地数量的45.02%。在相交重叠类型中,1次交叉重叠自然保护地最多,占相交重叠类型总数的75.56%;在重叠类型上,自然保护区与森林公园、自然保护区与风景名胜区、自然保护区与湿地公园、森林公园与风景名胜区重叠最为严重。该研究初步分析了湖南省自然保护地的空间重叠特征,并从整合、补缺、勘界调整等方面对全省保护地的整合优化提出了建议。

Abstract: The study of the spatial distribution and overlapping relationship of natural protected areas is an important basis for constructing the system of natural protected areas dominated by national parks. This study selected 582 natural protected areas of 9 types in Hunan Province as the research objects, aiming at putting forward the integration optimization countermeasures by using geographic concentration index and ArcGIS spatial analysis to analyze the spatial distribution and overlapping characteristics of protected areas in Hunan Province. The results show that the natural protected areas in Hunan Province are distributed in an aggregation manner, and the number of natural protected areas in Wuling-Xuefeng mountain area and Nanling mountain area accounts for 61.41% of the total number of protected areas in the province, which is a geographical ecological area with dense distribution of natural protected areas. The cities of Hunan Province, such as Xiangxi Autonomous Prefecture, Huaihua City, Shaoyang City, and Yongzhou City, are the administrative districts with a large number of natural protected areas in Hunan Province. The phenomenon of overlapping of natural protected areas is prominent and the number of overlapping protected areas accounts for 45.02% of the province's natural protected areas. Meanwhile, among the intersecting overlap types, the number of one overlap type is the most, accounting for 75.56% of intersecting and overlapping protected areas number. In terms of the types of overlapping protected areas, the overlapping between nature reserves and forest park, between nature reserves and scenic spots, between nature reserves and wetland park, and between scenic spots and forest park are the most common. On the basis of analysis of the spatial overlap relationship of natural protected areas in Hunan, this study put forward suggestions for optimization and integration of natural protected areas, including integration supplement and boundary adjustment.

Key words: Hunan Province, natural protected area, cross overlapping, optimization and integration
