以西湖湖区（湖心亭）、内西湖（西里湖）、西溪湿地内部河道（秋雪庵）、西溪湿地外部汇水口（蒋村港）4个监测点2014年全年监测数据均值作为评价对象，采用地表水环境质量标准中的单因子法，并选取高锰酸盐指数、氨氮和总磷三个指标，使用Spearman秩相关系数法对西湖风景区地表水水质进行分析，认为西湖风景区水质逐步呈现向好趋势，但游客行为会对水质产生一定影响，应适当控制机动游船数量，引导游客绿色游、生态游。
以西湖湖區（湖心亭）、內西湖（西裏湖）、西溪濕地內部河道（鞦雪菴）、西溪濕地外部彙水口（蔣村港）4箇鑑測點2014年全年鑑測數據均值作為評價對象，採用地錶水環境質量標準中的單因子法，併選取高錳痠鹽指數、氨氮和總燐三箇指標，使用Spearman秩相關繫數法對西湖風景區地錶水水質進行分析，認為西湖風景區水質逐步呈現嚮好趨勢，但遊客行為會對水質產生一定影響，應適噹控製機動遊船數量，引導遊客綠色遊、生態遊。

The monitoring data of four monitoring points were taken as the evaluation objects in 2014 , including Mid-lake Pavilion in West Lake, Xili Lake, Qiuxue Nunnery by XIxi Wetland internal lake and Jiangcun Harbor at Xixi Wetland ex -ternal catchment mouth .The surface water quality in the West Lake Scenic Area is analyzed based on three indicators -per-manganate index , ammonia nitrogen and total phosphorus , by adopting the approaches of single factor method of surface wa-ter environment quality standard and Spearman rank correlation coefficient method .The results show the water quality in the West Lake Scenic Area presents positive tendency , but the tourists behavior would be a certain influence on water quality . Therefore, it is necessary to limit the quantity of sightseeing boats and to advocate ecological tourism .
