| 摘 要： | 采用灰色关联度分析法对2006～2008年大沙河水库的23次水质监测数据进行了分析,得到叶绿素a与监测项目pH、DO、CODMn、WT、SD、TN、TP以及TN/TP的灰色关联度。结果表明,在环境理化因子中,叶绿素a与pH的关联度最大;在营养因子中,叶绿素a与TN的关联度大于其与TP的关联度。

| Abstract: | The grey relation analysis method was used to analyze 23 times of water quality monitoring data of Dashahe Reservoir from 2006 to 2008.And the grey relation degree between chlorophyll a and pH,DO,CODMn,WT,SD,TN,TP and TN/TP was obtained.The results showed that the grey relation degree between chlorophyll a and pH was higher than other environmental factors.Among nutrition factors,the grey relation degree between chlorophyll-a and TN was higher than that between chlorophyll a and TP. |
