摘要
为研究海河夏季浮游植物与环境因子的关系,2013年8月对海河浮游植物群落结构及水质因子进行了监测,并运用灰色关联分析方法对浮游植物丰度与环境因子关系进行了相关性分析。结果表明:海河夏季浮游植物丰度从上游至下游呈降低趋势:最高点出现在金汤桥,为12021×104 ind/L;最低点出现在二道闸,为583×104 ind/L。灰关联分析结果表明:对海河浮游植物丰度影响最大的环境因子是氮磷比,因此,控制氮磷输入对海河水质健康极为重要。
This study conducts a phytoplankton survey in summer in 2013 in Hai River of TianjinCity,and analyzes thecorrelation between phytoplankton abundance and environmental factorsbased on gray relationa-lanalysis. The results show that the phytoplankton abundancedecreases from the upperstreamto the lowerstream of Hal River in summer;the highest phytoplankton abundanceis 12021 × 104 ind/L in Jintangqiao site, and the lowest one is583 ×104 ind/L in Erdaozha site. The result of grey relational analysis suggests that the most influencing environmental factor is TN/TP ratio. Therefore,it is importantto control the nitrogen and phosphate inputto maintain the ecosystem health of Hal River.
