| 摘 要： | 采用2010年衡水湖监测数据,运用回归统计方法,分析衡水湖水体叶绿素a浓度变化特征,及其与TN、TP、TN/TP的相关关系,建立相应的回归方程.结果表明:衡水湖叶绿素a浓度在时间上变化规律与TP的变化较为一致,为7月、8月＞9月＞10月＞6月、11月＞5月,其对数与TP的对数呈明显正相关,与TN/TP的对数有显著负相关关系,而与TN的对数则无明显的相关性.

| Abstract: | Based on the conventional monitoring data in 2010,this paper,by the regression statistical method,studied the change of chlorophyll-a concentration and its relationship with total nitrogen(TN) and total phosphorus(TP) concentrations.The results indicated that the change was in accordance with the quantity change of TP,and the values were arranged as: July and August>September>October>June and November>May.At the same time,positive logarithmic correlation was found between chlorophyll-a and TP,and negative l... |
