摘要
本文从生态系统恶化及潜在危险方面,阐述了土壤侵蚀对生态环境的影响;并根据土壤物质循环过程失调、土壤薄层化少及土壤沙质化与石质化过程,探讨了侵蚀土壤退化的特点,最后提出了防治土壤侵蚀的对策及措施。
This paper expounds the effects of soil erosion upon ecological environment in the aspects of worsening eco-system and potential risks. In addition, based on the process of imbalance of cycling of soil materials, shallowness of soil layer, sandification and stonification, this paper discussed the behaviors of soil degradation, and suggested some countermeasures and practices for controlling soil erosion.
