北京顺义区地下水饮用水源地安全评价

在概括地下水饮用水源地安全内涵的基础上,从水质安全、水量安全、源安全、生态安全和管理安全五个方面构建地下水饮用水源地安全评价指标体系,用灰关联分析方法对北京顺义区6个地下水饮用水源地进行评价。结果表明:第二水源地安全状况最好,其他5个水源地也处于较安全状态,但是每个水源地依然存在不同方面的安全隐患。文中所构建的基于灰色关联分析的地下水饮用水源地安全评价指标体系,可以较为准确地反映研究区水源地的安全现状,具有实际应用价值。

Safety assessment of underground drinking water sources in Shunyi district of Beijing

Based on review of the safety contents of underground drinking water sources,a system of safety assessment indexes was established with the following five goals: water quality safety,water quantity safety,source safety,ecological safety and management safety.Six underground drinking water sources in the Shunyi district of Beijing were assessed according to the safety assessment system using the grey correlation analysis method.The results showed that the second underground drinking water source was the most secure and the other five were also in a relatively safe state,but there existed different security risks in each underground drinking water source.The index system established in this paper,based on the grey correlation analysis method for the safety assessment of the underground drinking water sources,can correctly reflect the current safety status of the study area and has practical value.
