摘要
采用回归统计方法分析白洋淀水产养殖区水质监测数据,研究白洋淀浅水草型湖泊夏季水体叶绿素a与环境因子的相关性,建立相应的回归方程。研究表明,白洋淀浅水草型湖泊水体叶绿素a含量与水温、pH、DO、COD、高锰酸盐指数呈显著正相关;叶绿素a与NH_4^+-N、NO_3^--N呈负相关,与NO_2^--N无明显相关,与TN无显著正相关;而叶绿素a与TP呈一定的正相关,白洋淀浅水草型湖泊可能是磷限制性湖泊。
The monitoring data was analyzed by regression statistical method,which is water quality monitoring data of aquaculture in Bai Yangdian. The correlation between chlorophyll-a and some environmental factors was studied,and the regression equations were created.Significantly positive correlations were found between chlorophyll-a and water temperature,pH,dissolved oxygen, permanganate indexes.And the negative correlations were found between chlorophyll-a and ammonia nitrogen,nitrate nitrogen,but not for nitrite nitrogen, total nitrogen.However,positive correlation was found between chlorophyll-a and total phosphorus. The results indicated that phosphorus might be the limited factot in the shallow weedy lake of Bai Yangdian.
