中文摘要	[目的]分析淤地坝坝控流域水土保持措施的合理性,为黄土高原的淤地坝建设与规划提供科学指导。[方法]对黄土丘陵沟壑区第一副区两座典型淤地坝进行分层土样采集,通过室内试验用常规方法对土样的颗粒组成进行了分析计算,在此基础上,利用分形理论,计算了分层土样颗粒组成的分形维数,分析了两座淤地坝坝地分层淤积物颗粒组成与其分形维数随淤积年限的变化趋势。[结果]两座典型淤地坝粒径组成的分形维数随淤积年限的增大都呈现逐渐减小的趋势。[结论]该典型淤地坝坝控流域不同土地利用类型表层或者更深层的土壤存在沙化趋势,淤积年限内坝控流域水土保持措施配置不合理。
英文摘要	[Objective]To analyze the rationality of soil and water conservation measures in order to provide a scientific guidance in basin system controlled by typical check dam.[Methods]Two typical check dams were selected,soil sample were collected,grain composition and fractal dimension were calculated,and the fractal dimension trends with the deposition years were analyzed by combining field tests and laboratory tests. [Results]The fractal dimension decreased with the depositing years increasing for the two typical check dams.[Conclusion]There existed desertification in surface or more deep soil of the basin systems controlled by two typical check dams,which showed that the configuration of soil and water conservation measures were unreasonable in the basin system controlled by two typical check dams.
