GROUNDWATER IN THE BEIHANCONG RIVER VALLEY OF SUIFENHE CITY, HEILONGJIANG PROVINCE: Water Quality Protection and Advice on Exploitation and Utilization
-
摘要: 为掌握绥芬河市北寒葱河河谷地下水的水质状况，向地方提供合理的水资源开发建议，本研究以地质、水文地质调查、水样采集等手段为基础，利用模糊综合评价法和层级阶梯法分别进行了研究区地下水水质和污染状况评价，应用物探测试、抽水试验等原位测试技术论证了区域地下水的富水性。以上工作基本查明了研究区地下水的水量和水质现状.认为研究区裂隙承压水一般为Ⅰ~Ⅲ类水质，污染等级为未污染水，水质状况较好，污染程度较低，宜于饮用；中生代构造破碎带涌水量可达350m3·d-1以上，建议地方政府应重点围绕构造破碎带开展物探找水，并开展地下水源地分区保护规划.Abstract: To grasp the groundwater quality of Beihancong River Valley in Suifenhe City and provide reasonable development advice to the local government, the fuzzy comprehensive assessment and hierarchical ladder methods are used to evaluate the groundwater quality and pollution situation respectively. The in-situ test techniques such as geophysical and pumping tests are also applied to demonstrate the regional groundwater abundance on the basis of geological and hydrogeological investigation and water sampling. The result shows that the quality of fissure confined water is generally at Grade I to III, in non-pollution level, which means suitable for drinking. Since the water inflow in the Mesozoic structural fracture zone can reach over 350m3·d-1, it is suggested that the local government should focus on geophysical water exploration around the fracture zone, and carry out the groundwater resource zoning protection planning.
