摘　　要：以巴楚县为研究区,基于耕地后备资源评价、新增耕地质量评定、高标准农田建设等相关标准,遵循综合性、层次性、代表性、可获得性原则选取指标,构建不稳定耕地评价指标体系,运用ArcGIS10.8软件的空间叠加分析功能划分不稳定耕地类型。结果表明,巴楚县不稳定耕地主要受生态安全性、生产适宜性和社会经济可行性3个方面13个因素的影响;巴楚县不稳定耕地有34 827.64 hm^(2),占耕地面积的24.15%,集中分布于巴楚县西南部及中部;巴楚县不稳定耕地分为生产不稳定型、生态不稳定型、社会经济不稳定型和混合不稳定型,分别占不稳定耕地总面积的1.50%、81.70%、14.82%和1.98%;巴楚县不稳定耕地面积较大,主要受盐渍化和荒漠沙化影响,可通过完善灌排系统和农田基础设施、加强防护林和高标准农田建设等方法提高耕地稳定性。Bachu County was taken as the case area.Based on relevant criteria such as cultivated land reserve resource evaluation,quality evaluation of newly added cultivated land and high standard farmland,an index system of unstable cultivated land evaluation was constructed by following the principles of comprehensiveness,hierarchy,representativeness and accessibility.The types of unsta⁃ble cultivated land were divided by spatial overlay analysis of ArcGIS10.8 software.The results showed that the unstable cultivated land in Bachu County was mainly affected by 13 factors in three aspects of ecological security,production suitability and socio-eco⁃nomic feasibility.The unstable cultivated land in Bachu County was 34827.64 hm^(2),accounting for 24.15%of the cultivated land area,which was concentrated in the southwest and central part of Bachu County.Unstable cultivated land in Bachu County was divided into production unstable type,ecological unstable type,social and economic unstable type and mixed unstable type,accounting for 1.50%,81.70%,14.82%and 1.98%of the total area of unstable cultivated land,respectively.Bachu County had a large area of unsta⁃ble cultivated land,which was mainly affected by salinization and desertification.The stability of cultivated land could be enhanced by improving irrigation and drainage system and farmland infrastructure,and strengthening the construction of shelter forest and high standard farmland.
