Abstract: The process of urbanization intensifying in recent years makes urban river face up huge pressures. Comparing with plain rivers, plateau rivers have unique water dynamic, geological features and ecological features. The earthquake took place in Jiegu Town, Yushu State, Qinghai Province on Apr. 14, 2010. Based on the investigation and analysis on the current situation, the problems are found out. According to the reconstruction thought of native and Qinghai Province, ecological environment protection and water culture reconstruction pattern are put forward on the basis of flood control and drain flood, which can support safe and comfortable foundation for ecological society development and human living. Combining ecological hydraulics and engineering hydraulics, the fishes are taken as protection goal to determine the plane modality and transection modes according to the characteristics of Zhaxike River and Batang River. The riverfronts are classified, and the three lines of waterfront are defined according to 'The General Plan for the Reconstruction after earthquake in Jiegu Town'. Some constructive suggestions on river management are proposed, which have great significance to sustainable development of Zhaxike River and Batang River, and also have important value for the management and protection for other basins.
