摘要
运用营养状态指数法、Shannon-Wiener多样性指数法和确定优势藻类法评价粤东10座主要水库2013年的营养化状态和浮游植物群落构成情况。其中,汤溪水库的营养化程度最高,接近富营养,蓝藻占绝对优势,藻类生物多样性指数最低,发生蓝藻水华的可能性较大;其余9座水库处于中营养的状态,属于硅藻-绿藻型,三坑水库的营养化程度最低。
The Eutrophication Index Method, the Shannon-Wiener Diversity Index Method and Determining the Dominant Algae Method are used to evaluate the eutrophication and the composition of phytoplarlkton of the 10 main reservoirs in the eastern Guangdong 2013. The eutrophication degree of Tangxi Reservoir is the highest, close to rich nutrition, blue-green algae cccount for absolute advantage, and the diversity of algal is the lowest, and the occurrence of cyanobacteria bloom possibility is larger. The other 9 reservoirs are in nutrition state, green algae- diatoms are dominant species, and the eutrophication degree of Sankeng resctvoir is the lowest.
