The post-disaster reconstruction of Wangmo County,located in the Southwest Autonomous Regionof Guizhou Province,is highly related to the vital interests of local residents and long-term development ofthe region.It is necessary to implement the scientific outlook on development comprehensively and carry outreconstruction division and function orientation concerning the practical situation of disaster areas by theprinciples of human-orientation,respecting nature,scientific planning and rational distribution.In finishinghierarchical clustering of its index system,national land development intensity,industrial development direction,population aggregation suitability and town construction are taken into consideration through a comprehensive evaluation of its environmental carrying capacity under the eco-environmental background of postdisaster area.By aquantitative approach with qualitative supplement and considering the integrity of administrative units for eco-environmental construction division,the post-disaster areas are divided into ecologicalreserve area (376.07km²),moderate reconstruction area (716.06km²)and suitable development area(407.47km²),which can guarantee us the control principle and town construction to be more reasonable andprovide us a theoretical support to post-disaster reconstruction planning layout through the analysis offunctional orientation.
