【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,使本就脆弱的岷江上游生态环境和水环境受到极大影响,岷江是成都市和都江堰市的主要水源,本次地震又发生在这两大城市的上游,震区中岷江水质直接关系到这两个城市的用水安全。本文根据跟岷江映秀段的水质监测结果,利用灰色关联分析法对水质进行综合评价分析,研究震后岷江水质特征,为岷江的水环境保护及成都与都江堰的饮用水安全提供参考。更多还原

【Abstract】 The Wenchuan earthquake is the most destructive one greatest intensity since the founding of New China,which impacted seriously the fragile eco-environment and water environment of the upper reaches of Minjiang River from where the water sources for the cities of Chengdu and Dujiangyan.The earthquake took place in the upper reaches to directly impact the water security of the two cities.Based on the water quality monitoring data from Yingxiu section of Minjiang River,the gray relational analysis was used to comprehensively assess the water quality and research the post-earthquake water quality characteristics of the Minjiang River.It provides references for water environment protection of Minjiang River and the safety of drinking water in the two cities.更多还原
