Based on the method of seismic landslide scale (volume) type which is divided into five levels, By the mathematical method discuss the landslide epicenter distance of two macroscopic epicenter (Yingxiu, Beichuan) intensity I_0≥XI extremely earthquake region (10 counties) in Wenchuan earthquake area. The distribution of earthquake slope and the landslide epicenter distance corresponds with sine, Gaussian and exponential decay laws. The maximum earthquake landslide epicenter distance is 120km, and the minimum landslide epicenter distance is nearly 0.25km. The result shows that the landslide scale and distribution scope induced by the earthquake have relationship with the landslide epicenter distance.
