大金钟水库水生生物群落结构特征
|
摘要
于2016年9、10、12月对大金钟水库开展了浮游植物、浮游动物、底栖动物和水生高等植物调查,共发现浮游植物7门63个分类单位,浮游动物15属20种,大型底栖动物2门3纲6目8科12属,水生高等植物13科14属14种。浮游植物丰度164.1×10~4~2 452.8×10~4cells/L,浮游动物丰度208.25~448 ind/L。基于底栖动物的ODP法和BI指数评价结果显示,实施水生态修复工程后,大金钟水库水质可能由轻污染向清洁好转。
Phytoplankton,zooplankton,macroinvertebrates and aquatic acrophytes in Dajingzhong Reservoir were investigated respectively in September 2016,October 2016 and January 2016. There were a total of 63 phytoplankton taxons belonging to 3 phyla,20 zooplankton species belonging to 15 genera,12 macroinvertebrates genera belonging to 2 phyla and 8 families,and 14 aquatic acrophytes species belonging to 2 phyla,13 families and 14 genera. The density of phytoplankton in the reservoir was from164. 1 × 10~4 ind·L~(-1) to 2452. 8 × 10~4 ind·L~(-1),The density of zooplankton in the reservoir was from 208. 28 ind·L~(-1) to 448 ind·L~(-11). Based on oxygen demander pecentage and biotic index of macroinvertebrates,it was showed that water quality of Dajinzhong Reservoir improved from slight pollution to clean probably.
