摘要: 长江流域国家级保护地数量庞大、保护类型多样,为了实现对长江流域自然资源的整体保护和管理的目的,从全域尺度分析其空间分布特征是梳理长江国家公园廊道构建的重要基础。通过数理统计与ArcGIS空间分析,结合中国自然地理表征和人文地理表征,对长江流域现有8类共计996处国家级保护地空间的分布特征进行了研究,结果表明:(1)长江流域国家级保护地总体呈集聚分布,并形成三江源区域、三江并流区域、川西高山高原区域、秦岭中段区域、渝西盆地区域、环洞庭湖区域、环鄱阳湖区域、黄山区域、环太湖区域9个集聚区;(2)长江流域国家级保护地主要集中在中切割高山区和中下游低山丘陵平原区,覆盖了河网密布、水资源丰富、植物种类繁多、土壤肥沃、可达性较高、人口密度适中及经济发展水平较高的东部和中部区域。基于其国家保护地空间分布特征,提出构建“长江源头—入海口”重要保护节点、“洞庭湖—鄱阳湖—巢湖—太湖”重要保护片区、“武当山—华釜山—大凉山、巫山—武陵山—药山”重要保护带的“三重要”模式与“国家公园先行区—国家级保护地聚集区—自然、社会、经济优势区—原生动植物本底”的“四层次”体系相结合的长江国家公园廊道空间策略

Abstract: Large national protected area in Yangtze river basin, various types of protection, in order to achieve the overall protection and management of natural resources in Yangtze river basin, the purpose of global scale from analysis of the spatial distribution characteristics of corridor is the study of the Yangtze river national park to build the important basis. In this paper, through mathematical statistics and ArcGIS spatial analysis, combined with the natural geography and human geography property in China, the existing 8 classes in Yangtze river basin spatial distribution characteristics totally of 996 nationallevel protected area are studied, the results show that (1) The national protected areas in the Yangtze River Basin are collectivity distribution, forming the Sanjiang source region, Three Parallel Rivers region, High alpine plateau area in Western Sichuan, the middle Qinling region, the basin area of West Chongqing, Dongting lake area, Poyang lake area, Huangshan area, ring Taihu area nine concentrated area; (2) The areas of national protection in the Yangtze River Basin are mainly concentrated in the region, where focused on middle cut high mountain aera, as well as low hill,hill and plain area in the middle and lower reaches, interconnected waterways, waterrich resources, a variety of evergreen plants, soil fertile, high accessibility, moderate population density and high level of economic development of eastern and central regions. Based on the national protected area spatial distribution characteristics of the Yangtze river, this paper proposed a space strategy for the corridor of the Yangtze River National Park, which are “the Yangtze river sourceentrance to the sea” important protection nodes, “Dongting lake, Poyang lake, Chao lake, Taihu lake” important protected area, “Wudang mountainHuafu mountainDaliang mountain, Wu mountainWuling mountain, Yao mountain” important protective belt “three importances” mode of protection zone, and “national park first areasnational reserve accumulationnatural, social, economic advantage areanative plants and animals background ” “four level system” with the combination of the Yangtze river national park corridor space strategy
