摘　　要：对杭州西溪湿地区域尺度内不同水体的水质状况进行了调查与比较分析.结果表明在区域水平上,西溪湿地区域空间范围内各水体水质不同:湿地公园内部水体质量好于外部水体,其中COD,TN,TP含量较公园外围保护地带水域中的含量分别降低29.6%,69.7%和56.1%,NH4+,NO3-和PO43-分别降低88.5%,77.9%和19%.在公园外围区域的水系中,北面水系相对较好.西溪湿地保护区内不同水体类型(大湖面、封闭水潭、通船河道)的水质也不相同,大湖面水体状况较好.The paper investigated and comparatively analyzed the water quality of different water bodies in Hangzhou Xixi Wetland region. The results show that there are remarkably different water quality of different water bodies in Hangzhou Xixi Wetland region. The water quality in the internal park is much better than that in the external park. Comparing with the water in the externel park, COD, TN and TP of the internal park decrease 29.6%, 69.7% and 56.1% respectively, NH4^＋ , NO3^- and PO4^3- decrease 88.5% ,77.9% and 19% respectively. In the external park, the water quality of the northern river is relatively better than that of the northern and the eastern river. In the internal park, the water quality is different in the big lake, the closed pond and the ship channel, the water quality in the big lake is superior.
