淮河流域山东段地下水质量评价

通过调查淮河流域山东段地下水污染现状,参照国家有关标准,采用单项指标评价法和内梅罗指数法,根据地下水区域分布特征和变化规律,并参考水质分析结果,选取了27项水质评价因子,对该区域浅层地下水上层水质、浅层地下水下层水质和深层地下水水质进行评价。评价结果显示:该区域地下水水质总体较差,大部分为Ⅳ类水质。然后对该区域的地下水污染进行评价,根据评价结果,针对该区域的水质问题提出相应的建议和改善水质的措施,为该区域的社会、经济的可持续发展提供科学依据。

Evaluation of groundwater quality in Shangdong reach of Huaihe River

Based on the investigation of groundwater pollution in the Shandong reach of Huaihe River and the relevant Chinese national standards,the single-parameter evaluation method and the Nemerow index method are adopted.According to the distribution characteristics and variation rules of the groundwater area,27 factors for the water quality are selected by means of the results of water quality analysis.The qualities at the upper and lower layers of shallow groundwater as well as the quality of deep groundwater in the area are evaluated.The results show that the groundwater quality in the area is generally poor,and most of it belongs to category Ⅳ.The groundwater pollution is then evaluated.According to the results,some suggestions and measures for the water quality problems in the area are proposed so as to provide scientific basis for the sustainable development of its society and economy.
