摘要:
Water cycle in the river basin constitutes the objective basis of water resources evolution.Whatever their manifestations,water resources problems can all attribute to the imbalances caused by the evolution of water cycle or its associated processes in the river basin.Various types of water activities for solution to water problems are in nature a regulation of "natural-social" dualistic water cycle or its associated processes in the river basin.
China is one of those countries which are faced with the most violent water cycle evolution and serious water problems with the Haihe River Basin as the most typical example.The Haihe River Basin has the least per-capita water resources among the ten In'st-grade river basins in China,but a dense population and developed economy.It now suffers from a prominent water resources decline,fierce competition between different water use sectors.In the view of the basic scientific and technological support required by water management and eco-environmental protection in the river basin,China in 2006 approved the National Basic Research Program of China entitled Evolutionary Mechanism of Water Cycle and Efficient Utilization of Water Resources in the Haihe River Basin,trying to build efficient utilization standards and patterns of urban-rural water resources on the basis of identifying the water cycle evolutionary mechanism in water-stressed river basins with intensive human activities.
