女山湖水化学特征及水质现状评价

THE ASSESSMENT OF HYDROCHEMICAL CHARACTERISTICS AND STATUS OF NUSHAN LAKE

通过对女山湖水体化学成份的分析，确定其水化学类型及基本特征，并对水质进行综合评价。结果表明：湖水属低矿化软水，ｐＨ偏碱，溶解氧丰富，水化学类型为重碳酸钙组Ⅱ型水，且以Ⅳ类水质为主，基本符合生活饮用，渔业等多种用途的需要。

Through the analysis of hydrochemical composition of natural water in Nushan Lake, the type and fundamental characteristics of hydrochemistry can be determined. The water is char-acterized by iow minieralized degree and hardness, rich dissolved oxygen, and low alkaline pH. The type of water is C1Ca.Besides, through the compositive assessment of water quality in this lake, the following conclusions can be given: grade IV occupies great majority of the whole water area of this lake. Therefoe, the water conforms to many uses: drinking, fishery and tourism, etc.
