摘　　要：近年来国内淡水湖泊浮游藻类监测一般以细胞数为计数单位,但现有的基于藻类数据的湖泊水质评价仅适用于藻类个体数。为此,本研究选择云南省玉溪市星云湖,开展基于藻类个体数监测的湖泊水质评价,检验其与基于化学指标的水质评价结果的一致性,比较理化指标监测与藻类个体数监测的优势和劣势,探讨今后开展藻类个体数监测工作的必要性。认为基于藻类个体数的水质评价方法可反映水生态环境的综合状况,有其独特价值,并且监测工作投入比理化指标监测少,但存在对技术人员的素质要求高、培训周期长、难以质控等缺点。In recent years,the monitoring of planktonic algae in freshwater lakes in China generally uses the number of cells as the counting unit.However,the existing lake water quality evaluation based on algae data is only applicable to the individual number of algae.For this reason,this study selected Xingyun Lake in Yuxi,Yunnan Province,to carry out lake water quality assessment based on algae individual number to check the consistency with the results of water quality assessment based on chemical indicators,and to compare the advantages and disadvantages between physical and chemical indicators monitoring and algae individual number monitoring,and to explore the necessity and feasibility of carrying out algae individual number monitoring in the future.The conclusion was that the water quality evaluation method based on the individual number of algae could reflect the comprehensive status of the water ecological environment and had its unique value,and the monitoring work investment was less than the monitoring of physical and chemical indicators.However,there were shortcomings such as high requirements for the accomplishment of technical personnel,long training time,and difficulty in quality control.With the improvement of the accomplishment of monitoring personnel and the development of new technologies,these difficulties were expected to be overcome.The monitoring of individual numbers of planktonic algae was still worth carrying out.
