平原河网地区水流流向复杂，影响引调水改善河网水质效果的因素众多。以浙江省杭嘉湖平原地区的上塘河流域为例，运用MIKE11水动力与水质模型并综合考虑上塘河引调水水量、历时及引水模式，研究了河网引调水改善水质的效果，并提出以引调水效率作为确定最佳引调水方案的依据。研究表明，阶段性引调水的效率优于连续性引调水，能在减少实际引调水历时与水量的同时，达到与连续性引调水相近的改善水质效果，从而在取得相近社会效益的同时，获得更佳的经济效益。
平原河網地區水流流嚮複雜，影響引調水改善河網水質效果的因素衆多。以浙江省杭嘉湖平原地區的上塘河流域為例，運用MIKE11水動力與水質模型併綜閤攷慮上塘河引調水水量、歷時及引水模式，研究瞭河網引調水改善水質的效果，併提齣以引調水效率作為確定最佳引調水方案的依據。研究錶明，階段性引調水的效率優于連續性引調水，能在減少實際引調水歷時與水量的同時，達到與連續性引調水相近的改善水質效果，從而在取得相近社會效益的同時，穫得更佳的經濟效益。

For plain river network area, the factors influencing effects of river water quality improvement by water diversion are various due to the complicated flow condition. We propose water diversion improvement efficiency as the judging basis to deter-mine optimal water diversion solution, and further carry out effect analysis on river water quality improvement by water diversion for Shangtanghe River watershed in Zhejiang Province using the hydrodynamics and water quality module of MIKE11 software, in which the diverted water quantity, diversion duration as well as diverted modes are comprehensively considered. The results show that the staged water diversion solution is better than the continuous water diversion solution, because it can obtain the same im-proving effect but consume less time and water volume, therefore the staged water diversion solution can gain the same social ben-efits and better economical benefits.
