Precipitation Resource Potential in Mountainous Areas in Hebei Province Analysis

The climatic conditions of Hebei Province cause this area shortage of water resources, man-made factors lead it more serious. In March 2007 in Hebei , 37 mountain counties got samples of soil and corn, conducted indoor tests, through analyzing Hebei rainfall and soil moisture and corn yield in mountains, using potential resource calculated model to precipitation, they analyzed and evaluated precipitation resource potential in mountainous areas in Hebei , concluded that precipitation is the important factor affecting the soil moisture content and maize yield. The development of storage-volume of precipitation resource potential is less than half, the theoretical storage-volume set of the potential development is lower, so that it is expected to improve the potential of development through technological improvements; Hebei runoff harvesting project should take rural residential areas as its core region; the precipitation of mountainous areas in Hebei Province is dominant factor affecting the amount of runoff harvesting.
