摘  要：
讨论了采伐、林地清理、整地、幼林抚育、林农复合经营、间伐等森林经营措施对林地土壤侵蚀的影响 ,指出凡是能降低林地覆盖和对土壤性状发生负面影响的森林经营措施 ,均会增加土壤侵蚀 ,且干扰程度越大 ,土壤侵蚀越严重 ,特别是在土壤抗蚀性弱和降雨侵蚀力大的地段更为明显。不合理的林木采集和林地清理方式会增加土壤侵蚀 ,而整地、幼林抚育、林农复合经营措施采用不当 ,亦会加剧幼林地土壤侵蚀。为此 ,应加强传统森林经营措施对林地生态系统影响的全面研究 ,在土壤侵蚀潜在危险性大的地段 ,应尽量降低经营措施对林地干扰强度 ,以达到保持水土 ,维持林地长期生产力的目的

摘  要：
Through overall discussing the effect of forest management practices such as harvesting, site preparing, soil preparing, tending and agroforestry managing, it indicated that any forest management practice influencing on land covering and soil properties can increase soil erosion. Further, the more the management practice disturbed the forest land, the more soil erosion was, this is especially obvious on the area that erosion durability of soil was low and rainfall erosivity high. Improper cut and site preparation may increase soil erosion; If site preparing, tending, agroforestry management were inappropriately employed, erosion may increase sharply, young stand soil, thus may directly affect the long term maintenance of stand fertility. In order to attain soil and water conservation and maintenance of stand long term productivity, the overall study on effect of traditional forest management practices on forest ecosystem should be strengthen and the disturbance intensity of management practices on stand be decreased to the full.
