摘要
通过对五里湖湖滨带水质的监测,Chla值范围为19.96～33.77 mg/m3;TN范围为3.51～7.15mg/L;TP范围为0.119～0.249mg/L;高锰酸盐指数范围为8.381～10.16mg/L;SD范围为0.35～0.58m。利用灰色聚类法对五里湖湖滨带进行富营养化评价,结果表明:该地区处于富营养状态。Chla与TP、高锰酸盐指数间呈显著的正相关关系,TN、SD与Chla间的相关性较差。磷是五里湖湖滨带富营养化的限制性因子。
Monitoring of lakeside zone of Wuli Lake indicated that the concentration of chlorophylla was 19.96～33.77mg/m^3, TN was 3.51～7.15mg/L, TP 0.119～0.249mg/L, CODMn 8.381～10.16mg/L and SD 0.35～0.58m. Grey clustering method was used to evaluate the eutrophication degree of the Lake, and results showed that the lakeside zone was at eutrophic level. There was significant correlation between chlorophyll-a and TP as well as CODMn while there was weak correlation between chlorophyll-a and TN as well as SD. Phosphorus was the limited factor of eutrophication.
