By comparing the initial analysis of the surface rupture on the Yingxiu-Beichuan fault, Pengxian-Guanxian fault, and Xiaoyudong fault caused by Wenchuan Earthquake, it was suggested that the plane fabric pattern of the surface rupture is consisting of two parallel thrust fault on the surface, linked by the Xiaoyudong fault, and the profile pattern of the rupture is consisting of two imbricated thrust fault in the profile. According to the features of the surface rupture of the Wenchuan earthquake and river response, the responses of channel vertical offsets to thrust faulting and the river lateral responses to the strike-slip faulting driven by the Wenchuan earthquake were described.The co-seismic tectonic effects on vertical channel offsets, lateral channel offsets, such as the Yingxiu-Beichuan fault, the Pengxian-Guanxian fault and the Xiaoyudong fault on the offsetting of river courses, river gradient, drainage pattern ,river valley, river profile, strike of the river channel , tectonic diversion of the river channel, tectonic slope-break of the river channel on the Minjiang river,the Jianjiang River,Baishuihe river and Mianyuanhe river were stated. Based on the relationship between the faulting driven by the Wenchuan earthquake and river response, it was concluded that the active tectonic effects on river profile, strike of the river channel, diversion of the river channel, slope-break of the river channel are very obvious.
