Abstract The soil erosion in Funiu Mountains Area is serious, and the implementation of ecological restoration in soil and water conservation is an effective way to solve the problem of soil and water loss.Aiming at resolving the suitability division problems in large-scale ecological restoration project, the dominant factor grading combination and the analysis methods of thematic map overlay were used to evaluate and zone the suitability of ecological natural restoration in Funiu Mountains Area. The results showed that 1) the three dominant factors including geomorphological types, land-cover types and the slopes of the ground, were proposed as the indexes in the suitability assessment and classification of ecological natural restoration; 2) According to the degree of suitability in the implement of protected conservation, namely the ecological natural restoration, three suitability grades of ecological natural restoration including suitability, temporarily unsuitability and unsuitability, were proposed in Funiu Mountains Area, and their regional distribution patterns were determined; 3) the suitability of ecological natural restoration in Funiu Mountains Area was divided into two regions ( A-level districts), four Subregions (B-level districts) and fifteen type regions (C-level districts). The research could provideeffective technical support for the layout in ecological natural restoration projects of soil and water conservation.
