摘 要: | 地下水水源地污染预警是集中城镇供水的地下水资源保护和管理的重要依据。为了控制地下水污染,使地下水保护更具预见性和主动性,提出了基于水质现状和污染风险的地下水水源地污染预警思路。水质现状是预警基础,决定预警的起始状态;污染风险考虑了污染源载荷风险和污染危害性,反映人类活动对地下水的影响,决定区域污染状况的发展变化。以浑河冲洪积扇饮用水水源地为例,通过各因子的评价和叠加分析得到地下水水源地污染预警值,结果显示浑河冲洪积扇地区大部分水源地存在不同程度的污染警情。研究结果可为当地地下水水源地保护提供依据。

Abstract: | Early w arning of g roundw ater so urce field pollution is an impo rtant base fo r water r eso urce pro tect ion and manage2
ment. In o rder to co nt rol g roundw ater pollutio n and impro ve the pr edictability and the initiat ive of g ro undw ater pr otectio n, this
paper pr oposed a new w ay for ear ly w arning of gr oundw ater so urce field pollution, based o n curr ent water qua lity status and
po llut ion r isk. Curr ent w ater quality is a basement and it det ermines the initial state o f pollution ear ly w arning. Po llution r isk in2
cludes pollution so ur ces load and po llut ion hazard. It reflects the influence o f human activities on g roundw ater and determines
the development o f reg ional pollutio n. This paper took the dr inking w ater sources in alluv ial2 pluv ial fan of H un River as an ex2
am ple, evaluat ed the ea rly war ning value thro ug h facto r assessment and over lay analysis. T he r esult s show ed that most gr ound2
w ater so urce fields in alluv ial2 pluv ial fan o f H un Riv er had suffer ed from pollutio n to some deg rees. The results can pr ov ide cer2
