北京怀柔水库的浮游藻类与水体营养状态
Planktonic algae and trophic state in Huairou Reservoir in Beijing City
摘要
Abstract
The planktonic algae and the main physicochemical factors were monitored in the Huairou Reservoir in Beijing City from 2009 to 2010. The results show that the average density of pknktonic algae was 988.16 x 10* ind./L, of which cyanobacteria accounted for 47.0%; three of the dominant populations were eutrophic indicator species, and two were mesotrophic ones; the Shannon-Weaver diversity index was 2.49, and the Pielou index was 0.37, indicating that the water in the reservoir was moderately polluted; and the 1^ index was 49.42, indicating that the water in the reservoir was in a mesotrophic state. The bivariate correlation analysis shows that Chl-a was positively correlated with TN at a high significance level of P < 0.01 and positively correlated with TP at a significance level of P < 0.05. It is pointed out that to control the point source pollution and non-point source pollution in the Huairou Reservoir, the Jingmi Diveision Canal, the Huaisha River, and the Huaijiu River, and to reduce the contents of TN and TP in the water can be considered principal measures against eutrophication in the Huairou Reservoir.关键词
