辽河铁岭段水生生物和微生物状况、评价及变化趋势

Condition,Evaluation,and Changing Trend of Aquatics and Microbes on the Section of Liaohe River along Tieling City

以2003年至2007年辽河铁岭段水生生物浮游植物、微生物监测数据为基础,应用Shannon-Wiener多样性指数法和Kolkwitz-Marsson污水生物系统法等生物学指标分析方法,分析辽河铁岭段水质状况,评价水质质量,划分水质污染等级,得出水质变化趋势。

Based on monitoring data of aquatics,microbes,and phytoplankters condition in the section of Liaohe river along Tieling City during 2003 through 2007,the water quality condition of the section was analyzed and evaluated using Shannon-Wiener diversity index methods and Kolkwitz-Marsson wastewater bio-system methods and other biological indices,to divide the pollution grade of water quality and obtain the changing trend of the water quality.
