摘    要:通过对各地坡面径流场试验资料的系统整理,结合梯田、林地、草地的减水减沙机理,引入径流、泥沙水平和措施质量概念,分析得出了不同质量的梯田、林地、草地在不同的径流、泥沙水平年份的减水减沙效益指标,形成了一套较为完善的梯田、林地、草地减水减沙效益指标体系。

关 键 词:梯田,林地,草地,减水效益,减沙效益

Preliminary Study on Benefit Indexes of Runoff and Sediment Reduction by Terraced Field,Forest Land and Grass Land
Abstract:The paper systematically sorts out the experimental data from slope runoff plots in different areas, draws into the concepts of runoff and sediment levels and quality of measures in combination with runoff and sediment reduction mechanism by terraced field, forest land and grass land. Based on this, the paper gives out the benefit indexes of runoff and sediment reduction by terraced field, forest land and grass land with different quality in years with different runoff and sediment level,and formed a set of perfect index system for runoff and sediment reduction by terraced field,forest land and grass land.
Keywords:terraced field forest land grass land runoff reduction benefit sediment reduction benefit
