摘　　要：研究利用GIS空间分析,采用综合模糊评价方法,以新型模糊综合水质评价模型(FCWQA)进行水质评价。以绍兴市为研究区域,选取5项具有代表性的水质指标进行评价。利用GIS生成绍兴市矢量网格地图以及研究不同时间下的水质状况,通过空间维度和时间维度,以更直观、更全面的角度进行评价。结果表明:绍兴诸暨市东南区域水质最优,西南和东北区域水质最劣,其余区域水质处于两者之间。监测时间内水质基本稳定,高锰酸钾指数和氨氮是影响水质的主要因素。Evaluate water quality with a new fuzzy comprehensive water quality evaluation model (FCWQA) by using GIS spatial analysis and comprehensive fuzzy evaluation method. Taking Shaoxing as the research area and selecting five representative water quality indexes for evaluation. Using GIS to generate the vector grid map of Shaoxing and study the water quality at different times which makes the evaluation become more intuitive and comprehensive perspective through the spatial and temporal dimensions. The results show that the water quality in the southeast of Zhuji city is the best, the water quality in the southwest and northeast of Zhuji city is the worst, and the water quality in the other regions is in between. The water quality was basically stable during the monitoring time, and potassium permanganate index and ammonia nitrogen are the main factors affecting the water quality.
