    摘要:

    土壤侵烛,不仅使土层变薄变瘦,旱灾频繁,而且造成江河泛滥,洪水成灾,良田毁灭,人畜伤亡的恶果。水土保持工作必须本标兼治,而以治本为主。治本是指各种田土一律实行免耕;治标是指增加农业投资,大搞农田基本建设,广泛植树造林,浚深大小河道,做到农田排灌两便,江河航运畅通。中国人民,终将会以改天换地的研究成果,实现“人定胜天”的诺言。

    Abstract:

    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.
