九坑河水库浮游植物特征与富营养化综合研究

Nine pit reservoir phytoplankton Features and Research of eutrophication

九坑河水库位于广东省肇庆市鼎湖区,离肇庆市区二十多公里,是省一级饮用水保护区,鼎湖区的自来水取水地,肇庆市的备用水源地。于2011年这一年的时间内对水库库中样点进行了调查,调查主要包括富营养化指标和浮游植物的种类和丰度等的生物指标。水库富营养化主要受到总氮含量的影响,浮游植物的优势种主要为硅藻和绿藻,要特别注意对总氮等营养源的量的控制,从而达到抑制水华种生长。

Nine pit river library is located in Guangdong Province Zhaoqing city Dinghu District, more than 20kilometers from downtown Zhaoqing, is the provincial level of drinking water protection area, Dinghu District Zhaoqing city tap water water, the stand-by water source. In 2011 this year to the reservoir in the sample were investigated, mainly including the survey indicator of eutrophication and phytoplankton species and abundance of biological indicator. Reservoir eutrophication mainly by the total nitrogen, the dominant species of phytoplankton mainly Bacillariophyta and Chlorophyta, paying particular attention to the total nitrogen and other nutrients quantity control, and thus inhibit algae growth.
