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.关键词
