The paper expounded t he problems on the w atershed water cycle research under the conditions of intensive develop2 ment and utilization of w ater resources. On the basis of these problems, the paper discussed the research met hods of w atershed water cycle to cope w ith the development and utilizat ion of w ater resources f rom four aspects, including the perception, experi2 ment, theory, and method. A mult i2objective model was developed based on t he coupling of w ater resources al ocation model and water cycle model, and it took the w atershed w ater supply and demand analysis and the comprehensive evaluation of watershed e2 cology, environment, and economy as the responses. The model was used to perform reasonable w ater resources allocation in the Yel ow River Basin. The results suggested that under the Yellow River suffers a serious water shortage under the current conditions, and water shortage can become more serious in future. Therefore, water saving can alleviate the serious water shortage problem.
