More than 5000 landslides or potential landslides have been triggered in the Three Gorges Reservoir （TGR） area since the impoundment in 2.03. Aimed at investigating the reservoir-induced landslides spatiotemporal and size distribution and its influence factors in the TGR by taking 790 landslides as statistical samples. The landslides exhibit significant regional and sub-regional differences in spatially， and numerous landslides occurred at the initial three impoundment stages and the corresponding following 2.3 cycles of reservoir operations， but the landslide frequency decreased dramatically after 2.10 in temporally. The relationship between landslide development and topographical， geological as well as hydrological factors were analyzed qualitatively. The reservoir-induced landslides in TGR area exhibit self-organized criticality and the rollover is nearly 2.5×104m2. which could not attribute to the data missing but the coupled influences imposed by affecting factors. Both the double Pareto and inverse gamma functions are more suitable than the power-law function to present the landslide size characteristics. In term of the fitting precious， the adaptability of the inverse gamma function is better if the landslide inventories are limited. The research results provide foundation for the landslide susceptibility maps and hazard risk assessment.
