摘要
为反映新丰江水库及库区地表水水质状况,确保新丰江水库水资源可持续利用,实现人、水和谐,研究以新丰江水库及库区地表水为研究对象,分析不同季度不同类型监测点地表水水质差异,并对水质进行综合评价。结果表明,不同监测点重金属(Cd、Pb、Cu、Zn、六价铬和总砷)含量均在国家地表水Ⅰ类标准内,表明研究地区水体未受到重金属污染;新丰江森林地表水和水库表层水综合评价均为国家地表水Ⅰ类水,新丰江库区水质良好;常绿阔叶林和针阔混交林地表水监测点水质最好,大坝至东江和水库监测点次之,水质最差为东江河源城区段上游监测点。研究表明,森林具有一定的净化水质作用,水库水注入东江中游后,对东江城区段中游和下游水质具有提升作用。
In order to reflect the conditions of surface water quality in Xinfengjiang reservoir areas, and promote the sustainable use of the water resource, this study analyzed the surface water condition in different sites in this area, and also conducted assessments on the surface water quality. The results showed that the contents of heavy metals, including Cd, Pb, Cu, Zn, Cr and As, in all different sites, all met the requirement of standard Ⅰ, indicating the water in the studied area was not affected by heavy metal. The results of water quality assessment showed that water from forest and reservoir sites met standard Ⅰ, indicating the water quality condition was good in these areas. The surface water quality was the best in evergreen broad-leaved and mixed broadleaf-conifer forests, medium level in reservoir and tributary, and worst in upstream of Dongjiang River. The study indicated that forest has the function of purifying water quality. The water quality in midstream and downstream of Dongjiang River was improved due to water supplement from the reservoir.
