摘要
汶川大地震是我国建国以来强度最大、破坏最严重的一次地震,给我国带来巨大的人员伤亡和经济损失。岷江上游流域生态环境较为脆弱,地震、泥石流、滑坡、崩塌等地质灾害经常发生,极易造成突发性水源污染。通过引入基于熵权改进的集对分析模型,对岷江上游流域映秀镇周边水源地进行综合评价,最好、平均、最差三种情况评价结果均为Ⅰ级。结果表明,"5.12"汶川特大地震对岷江上游流域部分水源地水质影响不大,震后岷江上游流域水质无明显变化。
The ecological environment in the upper reaches of Minjiang River basin is very vulnerable,and earthquakes,mudslides,landslides and other geological disasters occur frequently.After ＂5.12＂ Wenchuan Earthquake,the water quality in the upper reaches of Minjiang River Basin in Yingxiuwan Town are assessed by introducing the set pair analysis model which is improved by entropy weight.The results show that the earthquake has little effect on water quality of part of the water sources,and the water quality has no significant changes.
