Soil erosion not only causes the thining and poorness of soillayer, and frequent drought, but also various kind of disastrous consequences such as overflowing from rivers subsequent to soil erosion, flooding disasters, fertile land to be destroyed and the casualties of man or domestic animals. Soil conservation work must be performed to fundamental problems and the outward ones simultanenously, but harnessing the fundation is the major aspect. The so-called harnessing fundation refers to the way that the ecological no-till should be carried out on either sloping field or rain-fed and water-irrigated field. So, both soil erosion is eliminated and soil loss held back, and we could see the marvelous sense that grasses and trees are growing vigrously, all season looks green and abandant harvest of all food crops could be obtained wherever and whenever, accompanied with the comprehensive development of farming, forestry, husbandry and sideline production. The so-called harnessing outward problems refers to such activities as increasing agricultural capital to make capital construction of farmland greatly, planting trees and building forest in large scale, deeping and clearing all channels in order to make farmland be easy to irrigate or drain, and rivers be unblocked for shipping.
