摘要 本文论述了陕北黄土高原植被的性质,并以土壤分析数据说明植被破坏不仅影响土壤的机械侵蚀,而且使土壤的有机质、氮、磷、含水量等一些重要数值降低,一般程度不等的降低幅度为2—7倍之间;另外,恢复植被不仅能保持水土,防止侵蚀,更重要的是使土壤性质因素向良好方向发展,提高土壤肥力。 This paper explicates the vegetation characteristics and is representation with data of the soil analysis, destruction of the vegetation cover, which not only influences mechanical corrosion of the soil, but also influences diminution of the value of the important soil essence (orgonic matter,nitrogen, phosphorus, water, etc.) in the loess plateau of northern Shanxi province, it is more unhealthy the limit of diminution is in between 2-7 times under normal conditions; besides this restoration of the vegetation cover not only helps to conserve water and prevent soil erosion, but also essence of the soil essence is developed in good direction, fertility of soil is improved,it is more important. Vegetation cover ererts a physical influence and chemical action on the soil, both are an united process.
