红壤丘陵区坡改梯的水土保持效果研究

Effects of Terrace on Soil and Water Conservation in Red-soil Hilly Area

针对我国南方红壤丘陵地区坡耕地产生严重水土流失的现状,对比分析了坡改梯以后的水土保持效果。研究结果表明,坡改梯具有明显的保水保土效果,并且其保土效果要优于保水效果;而在同样坡改梯的情况下,植物措施和工程措施的结合,又能极大地提高保水保土效果。

Based on the status of soil and water loss in Red-soil hilly area of South China, soil and water conservation effects of terrace on soil and water conservation are analyzed. The results show that terrace has obvious soil and water conservation effects, and its soil conservation benefit is better than its water conservation benefit. Under the same condition of terrace, biology measure integrating engineering measure can greatly increase soil and water conservation effects.
