【摘要】 至今,全国的水土保持工作已取得了明显的成效,但还停留在定性描述和理论探索阶段,关于治理效益评价的深层次问题还未涉及,如水土流失治理模式与治理效益的关系问题,水土保持效益评价的原则与指标问题,水土保持措施和治理效益与治理目标关系问题,治理效益点与面的关系问题等。进一步研究这些问题,将会极大地推进水土流失治理效益评价理论体系的形成,从而加强治理效益评价的适用性和科学性。更多还原

【Abstract】 Up to now,soil and water conservation has already achieved significant benefits in China. However,the benefit assessment for soil and water conservation is far behind and remains in the stage of qualitative description and theoretical exploration. Some deep-seated issues have not been involved yet,such as the relationship between the control models of soil and water loss and their benefits,the regulations and indexes of benefit assessment,the relationships among measures,benefits and control aims,and the connection between point and area benefits of conservation. Researches and investigations on those issues will greatly push forward the construction of the theory system of benefit assessment and thus,prompt the applicability and scientific meaning of benefit assessment for soil and water conservation.更多还原
