摘要:
为给南方红壤水土流失区植被恢复提供科学依据，研究了植被恢复过程对南方红壤土壤侵蚀量变化过程的影响。①无论是自然坡造防护林还是坡改梯造经济林，在幼林、郁闭形成和林分结构形成阶段，均出现水土流失量明显减少、快速减少和急剧减少的变化过程；②自然坡按2：1：1：1配置的防护林、用材林、经济林和薪炭林体系，乔灌草搭配，至第7年，土壤侵蚀量可降至0.034 2 t/（hm2·a）；坡改梯造林至林分郁闭、结构形成后（造林第6年），土壤侵蚀量均小于0.029 t/（hm2·a）。③坡改梯造林的前3 a间种作物者土壤侵蚀量可降低44.65%～51.45%。
Abstract:
In order to offer the scientific foundation of vegetation resume,the influence of vegetation resume process on the corrasive volume of red soil in the south China was researched.(1)in the young forest phase,lush and shut form phase and woods frame form phase both in the shelter belt and economic forest,such movement process of washed-away tolerance as distinct decrease,fast decrease and rapid decrease were appeared.(2)in the nature slope that schemed according to 2:1:1:1 by fence forest,timber forest,economic forest and firewood forest,the erosive volume of soil reduced to 0.034 2 t/(hm2·a).the slope-changed-to-terrace forest,the corrasive volume of soil reduced to 0.029 t/(hm2·a).(3) in the former 3 years of slope-changed-to-terrace forest,the erosive volume of soil can be reduced by 44.65%～51.45%.
