| Summary: | In order to strengthen the ecological management and promote the rational utilization of land in nature reserve, this study used spatial analysis methods of minimum cumulative resistance model and geographic information system (GIS) and resistance evaluation index system, which included four factors of topography, ecological environment, human disturbance and eco-functional zone, to evaluate the land ecological suitability of Wanfo Mountain Nature Reserve in Hunan Province and gave some corresponding regulatory advices according to the spatial coupling relationship. The result showed that according to the ecological suitability of land, Wanfo Mountain Nature Reserve can be divided into four levels. The suitable area of grade Ⅰ was 4 036.04 hm<sup>2</sup>, where we should give priority to ecological protection and control all construction activities. The suitable area of grade Ⅱ was 3 828.51 hm<sup>2</sup>, where we should protect the landscape types such as rivers and ecological gardens and improve the function of the ecosystem. The suitable area of grade Ⅲ was 1 426.77 hm<sup>2</sup>, where we should take the ecological security as the bottom line, develop ecological agriculture and carry out the project of returning farmland to forest actively. The suitable area of grade Ⅳ was 692.11 hm<sup>2</sup>, where we should adhere to the principle of environmental protection and environmental construction, and focus on ecological construction. |
