摘要
Obtained before and after contrast earthquake field survey and this paper analyses the geological environment and the relative data of Baishui river basin in Pengzhou and compares the evolution characteristics of the geological environment in the basin before and after "5·12" earthquake in 2008.Considering the main factors affecting the geological environment and using the analytic hierarchy process to determine the value of each index,the paper divides the study area into 96 units of evaluation.Through calculating the evaluation value of the evaluation unit by the weighted average method,the geological environment of the study area is divided into four grades,that is,excellent,good,middle and poor.Among them,the ranges of the middle and poor ones,account for 65% of the entire study area.The results show that the overall geological environment is poor in the study area.
