摘要
为了解辛安水库的水质状况,对辛安水库进行了年内和年际水质和富营养化评价。水质评价采用单因子评价法、单因子水质标识指数法和综合水质标识指数法,富营养化评价采用卡森指数法和优势种法。评价结果表明,2013年辛安水库水质主要污染物质为有机物指标,无机物指标和有毒污染物指标均在Ⅰ类和Ⅱ类内,水质总体状况介于Ⅱ类和Ⅴ类之间。2009年~2013年每年6月~9月,辛安水库水质总体达到Ⅲ类水标准。2013年辛安水库富营养化水平12月份处于中-富营养化状态,8月份处于重富营养化状态,其余10个月份均处于富营养化状态。近5年辛安水库富营养化情况:2009年属于重富营养化状态;2010年~2013年辛安水库均属于富营养化状态。
In order to understand the water quality of Xin＇an Reservoir, water quality and eutrophication in Xin＇an Reservoir were evaluated monthly and annually. Water quality evaluation using the methods of single factor evaluation, single factor water quality identification index and comprehensive water quality identification index, eutrophication evaluation using the method of carson index and dominant species. Evaluation results showed that the main pollutants of water in Xin＇an Reservoir were organic indexes in 20t3, indexes of inorganic matter and toxic pollutants were between the category I and category Ⅱ , water quality in 2013 was between category Ⅱ and category Ⅴ. From 2009 to 2013, annual June to September, overall water quality in Xin＇an Reservoir complied with the category Ⅲ. In 2013, water quality of the reservoir was medium-eutrophication in December, heavy eutrophication in August, and the remaining 10 months were eutrophicated. In the past five years, water quality of the reservoir belong to heavy eutrophication in 2009, and eutrophied between 2010 - 2013 .
