摘要
通过对15°红壤坡地11个利用模式10年土壤侵蚀研究,认为红壤坡地土地利用模式中林作系统水土保持效果优于农作系统。林作系统中水土保持效果以常绿阔叶林最好,次为混交林,毛竹林和针叶林。农作系统中顺坡植物篱种植、等高梯化种植、顺坡水平沟种植水土保持效果较好。研究认为红壤坡地土地利用模式应以林作为主,尽可能发展高效的经济林。而如发展农业种植,则以顺坡植物篱种植模式最佳,次为等高梯化种植模式。
The effect of 11-different utilization model on sloping land with slope gradients of 15°in red soil region
of South China on soil and water conservation was studied. The results with ten-year research showed that the
forestry utilization model was better than the agricultural utilization model. The best utilization model among
forestry utilization models was evergreen broadleaf forest,then mixed forest, bamboo and coniferous forest. And
among agricultural utilization models terracing land and alley cropping were better. However, it adopted forestry u-
tilization models on red soil region of South China as far as possible. If using agricultural utilization models,the best
is alley cropping,then terracing land.
