摘要:

采用Microsoft Excel工作表和SPSS19.0软件Pearson相关性分析,统计2003年至2009年红枫湖水质监测数据,分析富营养化参数Chla、TP、TN、SD、CODMn与pH七年的存在量变化及各参数间的相关性。结果表明:1) Chla年均含量逐渐增加,TN浓度年均值在1.58 mg/L~3.39 mg/L、TP浓度年均值在0.07 mg/L~0.55 mg/L,超III类饮水标准;2) Chla含量与SD负相关,与pH、CODMn显著正相关,CODMn与pH呈极显著正相关,这与水体中浮游藻类的大量生长,悬浮物增加,水体中碳酸盐平衡系统被打破有关;3) Chla含量与TN显著负相关,与TP无明显相关性,TP、TN浓度显著负相关,这可能与水体水质的特殊性,水体中TP、TN浓度过高,水体营养物质丰富,浮游藻类的生长不再受其限制有关。

Using Microsoft Excel worksheet and Pearson correlation analysis of SPSS19.0 software, we counted monitoring data of Hong Feng Lake from 2003 to 2009, analysed the changes of eutrophication parameters Chla, TP, TN, SD, CODMn and pH in seven years, and then analysed their correlations. The results showed that: 1) The content of Chla increased every year, the annual average concentration of TN changed from 1.58 mg/L to 3.39 mg/L, the annual average concentration of TP changed from 0.07 mg/L to 0.55 mg/L, and the average concentration of TP supered III drinking water standards; 2) Chla negatively correlated with SD, significantly positive correlated with pH and CODMn, CODMn and pH were positively correlated highly, and all these correlations were due to that a lot of algae grew in water, suspended solids increased, and carbonate equilibrium system was broken; 3) Chla and TN were negatively correlated; Chla and TP had no significant correlation, and TP and TN were negatively correlated, which might be related to the growth of Planktonic algae which was no longer constrained to the special characteristics of Hongfeng lake, the too high concentration of TP and TN, and the rich nutrients.
