摘要
利用2000年西湖常规监测数据,通过聚类分析选取三个具有代表性的采样点, 用因子分析方法探讨了西湖水质各个参数之间的相互影响.结果表明,西湖水质主要受水温和营 养盐的影响,各水域由于所处的地理位置和受到钱塘江引水影响程度的不同又有各自的主要水质 影响因子,说明引水工程对改善西湖水质具有一定的作用.
Three representable spots, based on the data of 2000 in West Lake, are chosed by cluster analysis to study the relationships among the water quality factors, using factor analysis of statistical method. The results show that the water quality of West Lake is mainly influenced by temperature and nutrition. And because their locations and influenced extent of drawing water from QianTang River are different, each water area has it's own characteristic. It indicates that the project of drawing water has certain effect in improving the water quality of West Lake.
