摘　　要：根据河道分布状况、功能区划选取6个代表性样点在2008～2010年度对西溪湿地水体水质连续进行采样分析,根据分析结果利用综合营养状态指数法对西溪湿地水体富营养化程度进行评价.结果表明,西溪湿地水体2008年处于中度富营养化状态,2009年至2010年均处于轻度富营养化,且综合营养状态指数呈逐年下降趋势.最后对西溪湿地富营养化原因进行分析并提出相应的防治措施.Six representative sampling points were selected according to the distribution of rivers and function division. The ,water quality was continuously monitored with those points during 2008 to 2010. And the eutrophication degree of the water of Xixi national wetland park was assessed with comprehensive nutrition state index according to the monitoring results. The assessment results indicated that the water of Xixi wetland was middle eutropher in 2008,and that was light eutropher in 2009 and 2010. Fortunately, the comprehensive nutrition state indexes were declining during the three years. Finally,the causes of water eutrophication of Xixi wetland were analyzed and the corresponding control measures were suggested.
