Abstract
The landslide data were calculated in the Three Gorges Area of northeast Chongqing. The results showed that landslide frequency distributions of gradients accorded with the Weibull probability density distribution function. The landslide hazard ratios of gradients were acquired by Weibull accumulation probability distribution function in the different geological units. There was discord between landslide hazard ratio of different geological units and variance of landslide gradient. But they were approximate homology in the strate of Jurassic. The results indicate that the Weibull distribution can quantitatively evaluate the landslide hazard rations of gradients of the different strata in the Three Gorges Area.
