Methods of assessing the ecological geology of forest shallow cover areas in the Da Hinggan Mountains —— A Case study of 1∶25000 regional geological Survey, Fuzhong

Abstract：On the basis of the field survey and statistical analysis of a wealth of data about the fundamental geology, economic geology, environmental geology, tourism geology and agricultural (forestry) geology, and under the direction of the GIS technique, an integrated assessment of the ecological-geological pattern potential of exploitation and utilization of various resources in the forest shallow cover areas was carried out by using the semi-quantitative analysis and assessment method that combines the qualitative method with the quantitative one. Based on the study of the integrated assessment method of the ecological geology in forest shallow cover areas, the authors present a model for assessing the ecological geology of forest shallow cover area and determines the synthetic parameters, and moreover the types of ecological geology are also distinguished.
