Abstract: The water lacking problem in the North of China has been becoming the increasingly difficulty in the last decades of years. One of the basic causes is the strong evaporation besides the penury of precipitation and the very irregularity of the seasonal distribution of rainfall.
In the decades years to come, the cloud amount and rainfall of the summer in the central and the eastern part of North China will be increased following the increasing of CO₂ content in the atmosphere, the general rise in global temperature and the strengthening of the summer monsoon. There-fore, it is applicable for storing water used against a drought to build the great amount of reservoirs filling crushed stones in the edge of the mounta-in reg ions and in the hill regions. But, it has to depend on transfering water from the near drainage basin to supplement the lacking water of the western part of North China where the rainfall and the ice-snow resource on high mountains may become even more scarce in the future.
