摘　　要：针对大区域生态修复工程建设亟待解决的生态修复适宜性区划问题,采用主导因子分级组合法及其专题图叠加分析法,对淮河流域桐柏大别山区生态修复的适宜性进行了评价与分区研究。(1)用地貌类型(海拔高度)、土地覆被类型和地面坡度3个主导因子构建了生态修复适宜性评价与分区指标体系,并对指标因子进行了分类(或分级)和区域划分;(2)按照实施封禁保育(促进生态自我恢复)措施的适宜程度,提出了"适宜"、"暂不适宜"和"不适宜"3个生态修复适宜性等级,评价和确定了不同区域的生态修复适宜性;(3)按照生态修复适宜性将桐柏大别山区划分为2个生态修复区、4个亚区和16个类型区,可为在桐柏大别山区全面开展水土保持生态修复工程提供科学依据及技术支撑。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.
