| 摘 要： | 基于甘肃省水土保持统计年报等统计资料和多项科研成果,确定了甘肃省水土保持各项防治措施的有效面积、蓄水保土指标和措施产投系数,分析了各项措施的蓄水保土效益、经济效益、社会效益和生态效益。研究结果表明,建国60 a来,特别是改革开放30 a来,甘肃省水土保持工作在面上治理的基础上,组织实施的多项国家重点水土保持综合治理工程,取得了显著成效,为甘肃省农村社会经济的可持续发展和资源合理配置提供了基础平台;近30 a来甘肃省各项水土保持措施的蓄水、保土和经济效益累计分别达到1.10×1010m3,5.90×109t和288亿元。最后针对甘肃省当前水土保持工作中存在的主要问题提出了对策与建议。

| Abstract: | Based on the year books of soil and water conservations in Gansu Province and the findings of many research projects,the study quantified the effective areas,the runoff reduction coefficients,the sediment reduction coefficients and the production—devotion coefficients of the soil and water conservation measures.Meanwhile,we calculated the economic,social and ecological benefits of these measures.The results show that,in the last 60 years,especially the last 30 years since the economic reform and opening-up,the soil and water conservation comprehensive projects carried out in Gansu Province made remarkable contributions in providing basic platforms for the rural socioeconomic sustainability and reasonable allocations of natural resources.The results also show that the accumulative benefits in terms of runoff reduction,sediment reduction and economic value reached 1.10×1010 m3,5.90×109 t,28.8 billion yuan,respectively,in the last 30 years.At last,the paper provided associated suggestions according to the major problems found in the previous work. |
