运用水土流失影响指数对主体工程设计方案和水土保持方案进行定量计算、评价,可以在项目决策和前期论证阶段,修正完善设计方案,最大限度地预防项目建设可能产生的水土流失并降低对环境的负面影响,有针对性地提出保护、治理和恢复措施。介绍了水土流失影响指数的计算方法,阐述了如何运用水土流失影响指数定量评价主体设计方案并提出修正完善意见,针对水土流失影响指数大小总结提出了如何对水保方案进行总体评价,以及如何根据影响要素大小提出修正、完善意见。 Using the impact index of soil and water loss to quantitatively evaluate and evaluate the main project design scheme and soil and water conservation scheme, we can correct and perfect the design scheme in the project decision-making and pre-demonstration stage to minimize the potential soil erosion and decrease the environmental impact on the environment Negative impact, targeted protection, governance and recovery measures. This paper introduces the method of calculating the impact index of soil and water loss, expounds how to use the soil and water loss index to quantitatively evaluate the main design scheme and put forward the corrective and perfecting opinions. According to the size of the impact index of water and soil loss, it puts forward how to evaluate the plan of water and soil conservation, Affect the size of the elements put forward to amend and improve their views.
