本文比较研究了３种植被类型——光裸地、桉林与混交林对土壤的影响，结果表明，植物体内养分的含量相对独立于土壤中的养分供应，而主要是由植物自身的生理特性决定的．从长远看，它将导致土壤中某些元素的相对积累或其有效态含量的提高，长期的淋溶没有完全使土壤丧失生长植物的矿质养分基础，植被恢复对土壤矿质全量没有显著影响，不同类型的植被对土壤的改良与肥力发育有不同的影响．
This paper comparatively studied the effects of three types of vegetation - bare land, eucalyptus and mixed forest on the soil. The results showed that the content of nutrients in plants was relatively independent of the nutrient supply in soil, but mainly by the physiological characteristics of plants decided. In the long run, it will lead to the relative accumulation of some elements in the soil or the increase of their effective content. The long-term leaching does not completely lose the foundation of mineral resources for growing plants. Vegetation restoration has no significant effect on the total mineral content of the soil. Types of vegetation have different effects on soil improvement and fertility development.
