Abstract:
The paper expounded the problems on the watershed water cycle research with the high development and utilization of water resources. And on the basis of these problems, the paper discussed the watershed water cycle research methods to cope with the development and utilization of water resources from four levels of .perceive, experiments, theory and method. And it constructed a of the multi-objective control model that taking the water resources allocation and water cycle model coupling as the core, taking the watershed water supply and demand analysis and ecological, environmental and economic comprehensive evaluation as the response. The paper put the method into practice in the Yellow River, calculated the water resources rational allocation in the Yellow River with different water resources development and utilization condition. The results show that under the condition of current situation, the Yellow River basin suffer a serious water shortage, and it would be more terrible in the future, but the water saving can deeply alleviate water shortages.
