以甘肃黄土丘陵沟壑第五副区为研究对象,以1980-2012年甘肃黄土丘陵沟壑第五副区水土保持措施年报统计数据、甘肃省第一次全国水利普查为基础,以《水土保持综合治理效益计算方法》(GB/T15774-2008)为理论指导,就黄土丘陵沟壑第五副区30多年来水土保持取得的成效,水土保持综合治理效益的指标体系,对调水保土效益进行分析研究。结果显示,调水保土效益累计减流21.47亿m~3、减沙15.02亿t。
Taking the fifth sub-district of loess hilly and gully in Gansu as the research object, based on the statistical data of annual report on soil and water conservation measures of the Fifth Sub-district of loess hilly and gully region from 1980 to 2012 and the first national water conservancy survey in Gansu Province, Benefit calculation method "(GB / T15774-2008) as the theoretical guidance, the effectiveness of water and soil conservation in the fifth sub-district of loess hilly and gully area for more than 30 years and the index system of comprehensive benefits of soil and water conservation . The results showed that the total benefits of water and soil conservation were reduced by 2.147 billion m ~ 3 and sediment loss was 1.502 billion t.
