根据以往研究成果归纳出建立水保措施蓄水拦沙指标体系的基本思路和揭示差异性、遵循综合性、注重准确性、立足于可操作性的原则,结合黄土高原沟壑区的自然情况,建立了该区水土保持措施的蓄水拦沙指标体系。黄土高原沟壑区梯田、造林、种草的拦沙指标多小于黄土丘陵沟壑区相应措施的指标值,梯田的蓄水指标值大部分介于黄土丘陵沟壑区第一副区、第二副区与第五副区之间,提出了应用该指标体系的主要工作步骤。
According to the past research results, the basic idea and the difference of establishing the index system of water and sediment storage for soil and water conservation measures are summarized, followed by comprehensiveness and accuracy, based on the principle of maneuverability and the natural conditions of the gully area of the Loess Plateau Soil and water conservation measures of the area water storage silt index system. The sediment-removing indexes of terrace, afforestation and grass-planting in the gully area of the Loess Plateau were much less than those of the corresponding measures in the gully area of the Loess Plateau. Most of the water storage index of the terraced area were between the first sub-area and the second sub-area in the loess hilly and gully area Fifth sub-district, proposed the application of the indicator system of the main work steps.
