摘要
在进行区域环境评价时 ,对地下水环境的评价应当占有相当的地位。文章作者主要探讨了 :(1)对一个区域进行战略环境评价时 ,应当考虑当地的水资源和水环境条件 ,不能因为新上建设项目造成当地居民生活质量的下降。 (2 )正确处理少占耕地和保护水源的矛盾 ,既要保护耕地 ,也要保护水源。 (3)当河水与地下水有水力联系时 ,即使污水是达标排放的 ,也可能引起地下水的污染 ,使之不符合供水标准。对于此种情况应当慎重对待。 (4 )探讨了地下水污染源调查的要点。正确地认识和解决上述问题 ,有助于提高区域环境评价的质量。
With the largest population in the world, China is facing the problem of water resource shortage. Because groundwater has become the major source of water supply in north China, the groundwater environment evaluation should play an important role in the Environmental Impact Assessment (EIA). In this paper, the authors will discuss the following problems: 1. Groundwater resources and environment should be taken into consideration in the Strategic Environmental Assessment (SEA) since they are restricting factors for industrial projects. Power station, petrochemical company, iron and steel plants should not be built in the areas where water resources are in shortage. Such environment problems caused by exploitation of groundwater as groundwater contamination, land subsidence, karst collapse, seawater intrusion and disappearance of spring should be avoid carefully. 2. In order to protect the quality of groundwater, factories and waste dumping areas should not be placed in the recharge region of well field. 3. Groundwater could be contaminated by discharging wastewater into streams in areas where stream water recharges the groundwater, even if the wastewater may fit the 'Integrated Waste Water Discharge Standard'. Therefore, it is necessary to determine the discharge standard of wastewater according to the influence of polluted river on groundwater quality. 4. Investigation of pollution sources of groundwater should include the location of pollution and quantity of pollutant entering the aquifer. The authors believe that the above problems should be properly considered in order to improve the quality of environmental impact assessment.[KH2D][WT5HZ]
