隆宝湖水质变化特征研究
|
摘要
在隆宝湖湿地设置3个采样点采集水样,对水样的物理和化学指标进行分析与评价,为制定和实施隆宝湖生态环境保护提供依据.结果表明:隆宝湖水体温度、pH、电导率、矿化度、溶解氧(DO)、化学需氧量(COD)、五日生化需氧量(BOD5)、总氮、总磷、氯化物分别为13.40℃,7.9,0.66 ms·cm~(-1),0.40g·L~(-1),7.35mg·L~(-1),14.52mg·L~(~(-1)),2.86mg·L~(-1),0.67mg·L~(-1),0.015mg·L~(-1),45.50mg·L~(-1).采用代数叠加法对隆宝湖水质综合评价得出,2013年湖心采样点的水质为II类,湖西和湖东采样点的水质为III类;2014年湖心、湖西、湖东3个采样点的水质均为III类.
Three sampling points in Longbao Lake wetland were set and then water samples were collected to analyze and evaluate the change characteristics of water physical and chemical indicators,so as to provide foundations for formulating and implementing the protection of ecological environment.The results showed that:water temperature,pH,conductivity,degree of mineralization,DO,COD,BOD5,TN,TP,chloride were 13.40℃,7.9,0.66ms·cm~(-1),0.40g·L~(-1),7.35mg·L~(-1),14.52mg·L~(-1),2.86mg·L~(-1),0.67mg·L~(-1),0.015mg·L~(-1),45.50 mg·L~(-1)respectively.Algebraic method was utilized to proceed comprehensive evaluation of the water quality in Longbao Lake.In 2013 the water quality was class II for sampling point-center of the lake,while the water quality was class III for sampling point-west and east of the lake.In 2014,the water quality of three sampling sites in West Lake,East Lake,Center of Lake were all class III.
