摘　　要：伏牛山区水土流失危害严重,实施水土保持生态修复是加快区域水土流失防治步伐的有效措施。针对大区域生态修复工程建设亟待解决的适宜性区划问题,采用主导因子分级组合及其专题图叠加分析法,对伏牛山区生态自然修复的适宜性进行评价与分区。1)提出地貌类型、土地覆被类型和地面坡度3个主导因子作为生态自然修复适宜性评价与分区指标,并对其进行分级(分类)和分区;2)按照实施封禁保育(促进生态自然修复)措施的适宜程度,提出"适宜"、"暂不适宜"和"不适宜"3个生态自然修复适宜性等级,并确定其区域分布格局;3)将伏牛山区的生态自然修复适宜性划分为2个大区(一级区)、4个亚区(二级区)和15个类型区(三级区)。研究结果可为伏牛山区水土保持生态自然修复工程的规划布局提供技术支撑。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 provide effective technical support for the layout in ecological natural restoration projects of soil and water conservation.
