摘　　要：合理开发利用耕地后备资源是中国粮食安全的重要保障,而适宜性评价是其前提和基础。通过科学评估耕地后备资源的开发适宜性,可为区域土地资源合理配置和可持续利用提供科学依据。笔者以吉林省大安市为研究区,基于自然、社会、生态视角构建综合适宜性评价体系,采用层次分析法、景观格局指数和综合指数法进行系统分析,揭示了大安市耕地后备资源开发适宜性等级的数量、质量和空间分布特征,并提出相应的开发利用策略。结果表明:大安市耕地后备资源开发适宜性可分为最适宜、中等适宜、勉强适宜、不适宜4个等级,分别占全市耕地后备资源总面积的26.64%、38.83%、25.08%、9.44%;开发适宜性等级由大安市中部向东北和西南方向逐渐降低,最适宜和中等适宜开发区域主要集中在新平安镇和海坨乡,不适宜开发区域集中在西南部的龙沼镇;土地利用类型以盐碱地和其他草地为主,占全市耕地后备资源总面积的99.67%,盐碱地最适宜开发区域分布在西北部和东南部;其他草地最适宜开发区域集中分布在中西部。大安市耕地后备资源开发适宜性等级的空间分布差异显著,以中等适宜开发为主;应因地制宜地采取耕地后备资源的开发利用策略,盐碱地开发需关注水资源管理和盐碱地改良措施,其他草地开发需合理控制其开发力度,以维持区域生态平衡。Rational development and utilization of cultivated land reserve resources are essential for ensuring China's food security,while suitability evaluation is the prerequisite and foundation.By scientifically assessing the development suitability of these resources,it provides a scientific basis for rational allocation and sustainable utilization of regional land resources.The authors take Da'an City of Jilin Province as the study area and develop a comprehensive suitability evaluation system from natural,social,and ecological perspectives.Using methods such as AHP(analytic hierarchy process),landscape pattern indices,and composite indices,the authors conduct a systematic analysis to reveal quantity,quality,and spatial distribution characteristics of development suitability levels of cultivated land reserve resources in Da'an,and propose corresponding development and utilization strategies.The research results indicate that:the development suitability of cultivated land reserve resources in Da'an City can be categorized into four levels:highly suitable,moderately suitable,marginally suitable,and unsuitable,accounting for 26.64%,38.83%,25.08%,and 9.44%of total area of cultivated land reserve resources,respectively.Development suitability levels gradually decrease from central part of Da'an City toward northeast and southwest.Highly suitable and moderately suitable development areas are mainly concentrated in Xinping'an Town and Haituo Township,while unsuitable development areas are mainly concentrated in Longzhao Town in southwestern part of the city.Land use types are primarily saline-alkali land and other grasslands,accounting for 99.67%of total area of cultivated land reserve resources in city.The highly suitable development areas for saline-alkali land are distributed in northwest and southeast,while the highly suitable development areas for other grasslands are concentrated in the central and western parts.Spatial distribution of development suitability levels for cultivated land reserve resources in Da'an City s
