Study on the Evaluation Index System of Comprehensive Benefit of Water and Soil Conservation in Coal Mining Area

摘要

Based on the conception of DPSIR model, in according with the principle of corresponding, 5 factors, the driving force, pressure, state, impact and response are selected the evaluation index of comprehensive benefit of water and soil conservation in 20 coal mining areas. When starting from connotation of the comprehensive benefit of water and soil conservation in coal mining areas, experts grading method is used to select 15 basic indicators and to build the framework of evaluation index system of comprehensive benefit of water and soil conservation in coal mining areas. Using the method of AHP, the weight is confirmed among each subsystem and index (from the subsystem). Then the evaluation index weight system of comprehensive benefit of water and soil conservation in coal mining areas is finally calculated. The guidance of the evaluation of comprehensive benefit of water and soil conservation in coal mining areas could be provided in the future.
