Abstract：Analysis is made on the landslide triggering factor susceptibility in Xiaojiang watershed，Yunnan by means of landslide certainty factor (CF). The presented results are helpful to study the landslide mechanism and spatial distribution characteristics. The factors contributing the landslide occurrence are determined，including lithology，structure，slope，elevation and faults，etc..
