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
