水环境数学模型研究进展

水环境数学模型的研究按照时间可以划分为三个阶段。对每个阶段的特点和发展情况进行了详细叙述。阐述了水质模型在水质预测、水质规划评价、水环境容量计算和水质预警预报中所起的作用,以及在国内外的实际应用情况。介绍了当前国内外在各个发展方向上的研究进展,说明水质模型未来的六个发展趋势:新模型的开发,不确定性水质模型的研究,水质模型与“3S”的结合,多介质环境生态综合模型,人工智能和水质模型的结合,地下水和地表水转换的水质模型。

Development of water environment mathematic models

According to time sequence,studies on water quality models can be divided into three stages.Characteristics and development at each stage are reviewed in detail.The important role the water quality model plays in water quality prediction,planning and evaluation,water environment capacity calculation,water quality warning and forecast as well as its application in China and abroad are presented.Progress in each research field is reviewed.The development tendency of water quality model is discussed in six aspects,including development of new model,research on random model,integration of water quality model with "3S",multi-media ecological integral model,combination of water quality model with ANN,model for transformation of surface water and groundwater.
