坡改梯对水源区坡面产汇流过程的影响研究综述

概括了坡耕地水土流失现状、危害,提出坡耕地水土流失治理是保护生态环境和维系水土资源可持续利用的迫切要求,通过综合分析坡耕地水土流失治理各项措施及实施效果,指出坡改梯是25°以下坡耕地水土流失治理的主要水土保持措施。针对坡改梯蓄水保土和减少坡面径流并影响水源区水量这一现实问题,从坡面尺度总结分析了前人在坡耕地改梯田对土壤水分特征、产汇流过程及水量平衡的影响方面所做的研究工作,指出应加强坡改梯土壤水分特征曲线、产流特征及水资源量的影响方面的研究,以期为水源区水土资源综合利用提供技术支撑。

A Review Study on the Effect of Slope Fields into Terrace on the Runoff Process in the Water Source Area

This paper summarized soil and water loss situation and its harm in slope field,and pointed out that controlling soil and water loss of slope field was the urgent requirement to protect the environment and ensure the continuous utilization of soil and water resources.By comprehensive analysis of soil and loss control measures and their effect,it was concluded that slope fields into terrace was the main soil and water conservation measure for the slope fields under 25 degree.According to the problems that slope field into terrace not only conserved soil and water,but also decreased slope runoff,and even affected on the water amount in water resources area,the author analyzed the research work about the effects of slope field into terraces on soil water characteristic,runoff and water balance,and brought forward that the research about the effect of slope field into terraces on soil water characteristic curve,runoff features and water resources amount,so that it can provide the technique support for soil and water comprehensive utilization in water resources area.
