新建水源库区周边水域有机物及营养盐赋存特征分析

Characteristics of Occurrence of Organic Matters and Nutrient Salts in Surrounding Waters of a Newly Built Reservoir

选择新建金泽水库周边水域及太浦河为研究对象,测定了夏、秋季水体的常规水质指标并进行了富营养化评价。结果表明,各采样点夏秋季TN、TP浓度均超过国际广泛认可的水体富营养化引发临界值,平均浓度分别为1.65、0.15 mg/L;各采样点夏秋季平均综合营养状态指数为58.98,基本均处于轻度富营养化状态。此研究对该水域富营养化控制及水质质量保证有重要意义。

Surrounding waters of the newly-built Jinze Reservoir and the Taipu River were selected as the research objects. The routine water quality indicators were measured and evaluated for eutrophication in summer and autumn. The results showed that the concentrations of TN and TP in summer and autumn at each sampling point were higher than the internationally recognized threshold that would induce eutrophication. The mean concentrations of TN and TP were L 65 mg/L and 0. 15 mg/L respectively. The mean TLI(X) at each sampling point in summer and autumn was 58. 98. Almost all the sampling points were situated in light eutrophication. This study is of great significance to the control of eutrophication in the studied waters and guarantee of water quality of the Jinze Reservoir and Taipu River.
