本文根据调查资料统计,对黄土高原东部有典型性、代表性的皇甫川流域的土壤侵蚀的严重退化,进行了全面论述。文中指出,由于严重的水土流失和风蚀沙化,350年后土壤资源将濒临枯竭。拯救和保护土壤资源刻不容缓。通过土壤资源的适宜性评价与土壤利用现状比较,指出土壤资源利用不合理是导致土壤侵蚀退化的根本原因。最后指出了以生态学观点为指导,防治土壤侵蚀退化为目的,建立自给和半自给型的农业,保护型的林业,商品性的牧业为总方针,进行高效生态农业的土壤改良、利用和保护的途径与措施,为黄土高原地区制定国土整治规划提供一定的科学依据。
Based on the survey data, this paper discusses the serious degradation of soil erosion in the typical Huangfuchuan basin in the eastern Loess Plateau. The article pointed out that due to severe soil erosion and erosion of the sand, 350 years after the soil resources will be on the verge of drying up. Saving and protecting soil resources is urgent. Through the comparison of the suitability of soil resources and the status quo of soil utilization, it is pointed out that the unreasonable utilization of soil resources is the fundamental reason for the degradation of soil erosion. Finally, it points out that taking the ecological point of view as the guide and preventing and controlling soil erosion degradation as the goal, establishing self-supply and semi-subsistence agriculture, protected forestry and commercial animal husbandry as the general guideline, carrying on the soil improvement, utilization and Protection measures and measures to provide certain scientific basis for the formulation of land readjustment planning in the Loess Plateau.
