| 摘 要： | 2009年3月、5月、8月、11月在全长41.7 Km的瓯江干流丽水段设10个站点,对DO、CODMn、NH3-N、TN、TP等5项水质指标进行了测定,并运用营养状态指数对水体水质进行了分析和评价。结果显示,2个站点水体水质达到地表水环境质量Ⅲ类标准,5个站点水体水质为Ⅳ类标准,3个站点为Ⅴ类标准。评价结果显示2009年全江段水体水质的营养水平全部为中营养水平。

| Abstract: | Water quality in ten stations of Lishui section of Oujiang River was evaluated based on five water parameters like DO,CODMn,NH3-N,TN and TP investigated in March,May,August and November in 2009.Comprehensive trophic state index TLI(∑) was used to value the water trophic state.The results showed that of ten stations examined,two stations was considered as grade Ⅲ in water quality,five stations as grade Ⅳ,and three stations as grade Ⅴ,according to surface water environment criteria of China(GB3838-2002).The evaluation result of TLI(∑) indicated the water quality of ten stations in 2009 was at meso-trophication. |
