Aiming at resolving the ecological restoration suitability division problems within ecological restoration engineering construction in large-scale area

the authors evaluated the suitability of ecological restoration and zoning in Tongbai-Dabie mountains area by adopting the grading combination of dominant factors and thematic map overlay analysis methods. The results showed that:(1) The three dominant factors including geomorphological type(altitude)

land cover type and the ground slope were proposed as the indexes for suitability assessment and zoning of ecological restoration.(2) According to the suitability degree in implement of enclosure measures(to promoting ecological natural restoration)

the three levels in ecological restoration suitability including the "appropriate"

"temporarily unfit" and "unfit" in Tongbai-Dabie mountains area was got in order to evaluate and determine ecological restoration suitability in different areas.(3) The Tongbai-Dabie mountains area was divided into two ecological restoration districts

four subdistricts and sixteen facilities in accordance with their ecological restoration suitability. The research could provide effective scientific basis and technical support for the ecological restoration projects in Tongbai-Dabie mountains area in soil and water conservation.
