[Objective] The key natural factors affecting the distribution of landslide disasters induced by mountain torrent in the Xiangxi catchment, which represents the Sichuan-Hubei fold mountain area inner Eastern Three Gorges Area, was studied in order to provide scientific support for the regional prevention and control of the mountain torrent and geologic disasters. Besides, the performance of Geodetector model was also discussed.[Methods] The quantitative relationships between the regional torrent-landslide distributed pattern in disaster-prone mountain and its main natural impact factors was analyzed based on field investigation, GIS, general statistic method and Geodetector.[Results] The stepwise regression analysis indicated that the main five factors, i.e., lithology frangibility, fault range, NDVI, extreme value of storm and lithology hard degree can totally explain 80.6% of the variation of the pattern, and the contributions of them were 28.6%, 19.8%, 18.9%, 16.4% and 16.3%, respectively. The Geodetector analysis indicated that the main factors were lithology frangibility, fault range, NDVI, soil erodibility and lithology hard degree, their contributions were 24.5%, 20.9%, 18.3%, 16.3% and 14.8%, respectively. The interactions between lithology frangibility and the two vaiables of NDVI and slope, can explained 68.8% and 62.0% of the pattern, respectively.[Conclusion] The regional mountain torrent-landslide disaster pattern were mainly controlled by lithology, fault and vegetation cover. The harder the rock was, and the farther from the fault, and the higher cover level of vegetation, the less the mountain torrent-landslide developed. The Geodetector is suitable for the nonlinear geographical phenomenon in general. However, the linear characteristic of independent variable is ignored in this method, and naturally the repeatability among the variables cannot be distinguished. Therefore, the classic statistical method should be combined for understanding the results comprehensively.
