Abstract：The models for river-lake protection and restoration should be spatially differentiated considering the heterogeneity differentiation of river-lake ecosystem and differentiation of human activity disturbance. According to the analysis of connotation and theory of spatial differentiation for river-lake ecological conservation and restoration and features of ecology in China, four types of models are divided, including those with high risks of ecological degradation, dominated by water scarcity, dominated by water pollution and spatial occupied or with barriers for river connection. The proposed models are designed especially for each type and composite areas for ecological restoration, in order to accumulate experiences for ecological recovery of rivers and lakes in China.
