彭州市白水河流域地质环境演化及评价
|
摘要
通过对四川彭州市白水河流域地质环境的实地调查及相关资料的分析,对比2008年"5.12"地震前后流域内地质环境演变特征,并综合考虑自然地理、地层岩性、地质构造、地震、水文地质条件等影响地质环境的主要因素,用层次分析法确定各指标权值,然后将研究区划分为96个评价单元;通过加权平均法计算各评价单元的评价值,并且按评价值范围将研究区划分为地质环境优、良、中、差4个等级。其中处于中、差2个等级的范围占整个研究区域的65%,结果显示研究区整体地质环境质量较差。
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.
