水土保持投资费省效宏。据统计分析,1949年至1987年的38年中,黄河流域水土保持治理措施保存面积达12.3万km~2,各项措施全部生效共可蓄水259.7亿m~3,减少土壤侵蚀70.2亿t,增产效益达195.07亿元,相当于治理投入的3倍多。文章通过分析水土保持经费来源渠道、数量和使用情况,建议国家增加对黄河流域水土保持工作的投入,按系统、按项目下达,充分发挥流域机构的作用。并在总结各地经验的基础上,对水土保持投资方向、使用管理提出了改革意见。
Saving soil and water conservation investment efficiency macro. According to the statistical analysis, in the 38 years from 1949 to 1987, the conservation area of soil and water conservation measures in the Yellow River Basin reached 123,000 km ~ 2. All the measures took effect to save 25.97 billion m3 of water and reduce soil erosion by 7.02 billion tons , Increase production efficiency of 19.57 billion yuan, equivalent to more than 3 times the investment in governance. By analyzing the sources, quantity and usage of sources of funding for soil and water conservation, the paper suggests that the state increase its input to soil and water conservation work in the Yellow River Basin and give full play to the role of river basin agencies according to systems and projects. On the basis of summing up the experiences of all localities, we put forward reform opinions on the investment direction and management of soil and water conservation.
