Abstract: Bailongjiang Valley is one of the four major geological disaster prone areas.1030 landslides are found by the combination of remote sensing technology and on-the-spot investigation in the research areas. Based on the GIS space analysis method, two statistical indicators, namely landslide number and density, were used to count 8 parameters of formation lithology, slope height, slope direction, slope angle, the fault buffer, the river buffer, the road buffer and the land types. The statistical results of 1030 landslides distributed in 6 counties suggest that, landslide distribution of Bailongjiang valley in Gansu province mainly showed the following characteristics:(1) the landslides mainly distribute in the S and SE slope, the range of 0~20 degree, and mainly distribute in the phyllite, slate, thin limestone rock group and the thick layer of limestone, slate rock group district; (2) the height of 1300~2000m occupies in the largest number of landslide, while landslide density maximum in 600~1300m height; (3) the number and density of the landslide decreases with the increase of fracture, river and road distance; (4) the landslide mainly concentrated in the farming area, followed by the grass area.
