摘　　要：将水质监测数据与空间数据结合,建立了具有时空特征的洪泽湖水质数据库.通过对水质的相关性分析,将参数的重要度进行排序,作为数据选取的依据.在因子分析的基础上,通过Delphi法,结合空间数据,研究了主要因子的内含及时空变化规律.提出湖泊污染的“原初性”和“次生性”污染分量的概念,并分析了各分量的净化差异.建立了富营养化指数(F3)的模拟方程.Integrating the water quality monitoring data and the spatial data, the database of Hongze Lake water quality was established. Based on analyzing the correlation matrixes, the importance degree of parameters was arranged with their precedence order as a basis for selecting the data, and by using of Delphi technique combined with the spatial data, the implications of main factors and their spatial change rule were studied, and the concepts of original and secondary pollution component were suggested and their differences in purification were analyzed. The F3 (eutrophication index) simulation equation was established.
