辽河流域平原区浅层地下水水化学特征和水质状况

Water chemistry characteristics and water quality state of shallow groundwater in plain of Liaohe river basin

本文根据多年地下水水质监测资料和近期实测监测资料,系统地对辽河流域平原区浅层地下水的水化学特征进行了分析,并对浅层地下水的水质类别及水质污染状况进行了分析评价。结果表明:平原区地下水化学类型以重碳酸盐型为主,浅层地下水有污染加重和扩大的趋势。

The paper analyses the water chemistry characteristic of shallow groundwater in plain of Liaohe river according to monitoring data of groundwater in many years, appraises the category of water quality and the pollution state of water quality for shallow groundwater. The result indicates that the water chemistry category of groundwater in the plain takes the dense carbonate category as the dominant factor, the pollution of shallow groundwater becomes more serious and has the expanded tendency.
