Silt-trap dam is a type of projects used for intercepting and depositing sediment in channels with serious soil erosion. Its construction is of great significance to controling soil erosion, improving ecological environment quality, realizing regional sustainable development, and insuring ecological safety in the Loess Plateau. Although much progress has been made in silt-trap dam construction since the founding of P. R. China, until now, there are still many important theoretical problems that need further study. The systematic research of the effects of geographical factors on dam system construction is insufficient and needs special attention. This paper first selected the main geographic factors that may influence silt-trap dam construction and reviewed the related previous studies, employed a methodology that combined qualitative analysis and quantitative accumulation, macroscopic research and microscopic case analysis, analyzed the influences of soil erosion modulus, channel density and rural population density on silt-trap dams construction in small watersheds. Finally, this paper selected the case study area in the arenaceous and coarse sand region, mid-stream of the Yellow River, studied the main factors that resulted in the spatial variation and restriction of silt-trap dams construction using GIS technology. The main conclusions of this study are: (1) The density of silt-trap dam is not significantly related with physical geographic factors, although the physical geographic factors represented by soil erosion modulus and channel density are important factors that need to be considered during silt-trap dam plan and construction. (2) Human geographic factors represented by rural population density have significant influence on silt-trap dam construction.
