Criss-crossing drains, water pipes, dotted cellar and water well moisten fresh life, bred hope for good harvest, and told the world about 2.6 million diligent and industrious Longnan children and the moving “story” of drought resistance.

Even more “fatal” is that precipitation and water demand in the time and space there is a serious dislocation: First, the meteorological data of the highest rainfall and rainfall required for agricultural production dislocation; Second, the three-dimensional distribution of precipitation on the region Dislocation; Third, the region’s horizontal distribution of precipitation on the wrong place; Fourth, precipitation time and agricultural production in the season dislocation; Fifth, the river and arable land dislocation; Sixth, uneven
