平原河网水流水质数值模拟研究展望

论述了河网地区主要水量、水质模拟方法的基本理论、发展过程及其在生产实践中的应用状况，并从理论与应用角度分析了现今广为应用的水流、扩散质数值模拟方法的优缺点，同时在此基础上提出了改进数值模拟方法的设想：根据陆域特征研究适用于河网地区的面源污染负荷模型；根据交叉口扩散质输运特征研究河网水质精细模拟方法．

Prospects of water quality numerical simulation for plain river network

The basic theories on numerical simulation of water quantity and water quality for river network regions and their development and application to the fields of water resources harnessing, navigation, and water environment planning are summarized, and the advantages and disadvantages of the numerical simulation methods for water flow and diffusive substances currently used are analyzed from the angles of theory and application. Then, some suggestions for improvement of current simulation methods are made, i.e. to develop an area-source pollution model for river network regions according to the land characteristics, and to study a refined water quality model according to the transport features of diffusive substances through the intersection of river channels.
