摘　　要：在对2005年7月至2006年5月二龙山水库相关水质指标进行监测分析的基础上,评价了水库的总体水质,鉴定和检测了水库的藻类和藻毒素,探讨了水库水体变色的原因。研究结果表明,二龙山水库总体水质为V类和劣V类,为中度污染和重度污染,主要污染物为总氮和总磷,已呈现富营养化状态,可能诱发水库水华的发生。水体的富营养化和铜绿微囊藻等藻类的大量繁殖是水库水体变色的主要原因。Based on monitoring and analysis of change of water quality index from July 2005 to May 2006, the wate quality evaulation, identification and detection of algae and algae toxin and cause of water color-changing were discussed. It is found that general water quality of Erlongshan Reservoir were moderate and severe pollution due to grade V and low grade V , the primary contaminant TN and TP lead to eutrophication and algal boom which resulted in the water color-changing in the Reservoir.
