【摘要】 自１９２５年建立第一个水质数学模型以来，经过近七十年的研究与发展。现在，已提出了许多不同的模型。国外对水质数学模型的开发研究可分为四个阶段，计算方法由一维发展到三维。国内已在确定性模型方面作了较为深入的研究与应用。目前，水质数学模型有两大方向：（１）应用新技术不断改进已有模型；（２）建立和应用非确定性模型。更多还原

【Abstract】 Since the first water quality mathematical model was presented in 1925, through nearlg seventy years study and develop, many different models have been prosented. The process of studying this models in abroad can be devided to four periods, calculation method has been developed from one-dimension to three-dimensions. Definite models have been thorougly studied and applied in home. Now the two developing directions of models are continuously using new technique to improue existing models and build up and apply indefinite models.更多还原
