In land planning reserve some land as a support and rely on the ecosystem is necessary, also essential. On the limited land resources, how to delineate ecological land region scientifically and reasonably is an important research topic that the land planning faces. Based on analysing the domestic and international research general situation, this paper discusses the theory of ecological land region and the methods, and takes the research in Wuming County as a case study.The theoretical basis of ecological land region includes the theory of sustainable development, ecosystem services theory and the theory of ecological security.

Then by the use of index method, overlay analysis method and comprehensive integration method, the ecological evaluation respectively to headwaters self-restraint, soil keeps, biodiversity maintenance of the study area is carried on, it contains ecological environment-sensitive assessment and ecosystem service function importance evaluation and ecosystem service value evaluation, and then it makes the comments the basic to be high uses for the ecological land region according to the results of evaluation.In accordance with the method of ecological land region and Software support in Mapgis,the ecological evaluation respectively to Wuming headwaters self-restraint, soil keeps, biodiversity maintenance is carried on and format a series of ecological evaluation map that Wuming ecological land region is divided by. Finally, the region headwaters self-restraint and biodiversity maintenance, headwaters self-restraint, soil keep and biodiversity maintenance, soil keep to etc.4 types of 11 ecological land region is divided. The thesis puts forward the protection countermeasure to the problems that exist in each kind of ecological land regions, it provides a scientific basis for Wuming County ecology land protection layout research, and also provides reference for other areas carring out the ecological land region studying.
