水土保持是国土整治的重妥组成部分,防治水土流失已经列为长期坚持的一项国策。建国四十年来,我国水土保持取得了很大的进展,特别是十一届三中全会以来,水土保持有了新的突破,从小流域为单元实施治理措施结出了丰硕的果实,经济效益显著,大大提高了当地群众生产,生活水平。然而,我国水土流失还很严重,还有大量的流域急待进行治理,尽早获得经济效益。过去较少用经济方法去评价水保措施规划,设计方案的合理性。著者认为,在进行水保规划,设计方案比较时,应增加经济评价内容,使得选出的方案经济上是合理可行的。
Soil and water conservation is a crucial component of land consolidation and the prevention and control of soil and water loss have been listed as a national policy that has long been adhered to. Since the founding of the People’s Republic of China, great progress has been made in water and soil conservation in our country. Especially since the Third Plenary Session of the 11th CPC Central Committee, new breakthroughs have been made in soil and water conservation. Fruitful fruits have been achieved through the implementation of governance measures in units of small watersheds, with remarkable economic benefits , Greatly improving the local people’s production and living standards. However, the soil and water loss in China is still very serious, and a large number of river basins urgently need to be dealt with so that they can obtain economic benefits as soon as possible. In the past, less economic methods were used to evaluate the rationality of planning and design of soil and water conservation measures. The author believes that in the comparison of planning and design of soil and water conservation, the content of economic evaluation should be increased so that the selected scheme is economically feasible.
