Abstract
The geological environment is the basis of ecological planning. In this article, the factor analysis combined with Analytic Hierarchy Process (AHP) and GIS (geographic information technology) was used. The method sets geological disasters, landform type, surface slope, soil type and erosion as ecological suitability of geology factor; distribution of surface water, precipitation distribution, hydraulic engineering and degree of groundwater development as ecology suitability of water resources. Huairou, located in Beijing, was set as an example through the method. The article evaluated the suitability of the geological environment to ecology and solved quantitative description about the key technologies of the degree of influence to ecology which is affected by the geological environment. In the end, a theoretical guidance and a kind of technical method of establishing a scientific ecological planning system and guiding ecological planning were provided.
