摘    要:为进一步明晰高标准基本农田在耕地质量、建设难度、建设时序之间的关系,该文以重庆市垫江县为例,借助高分辨率SPOT5遥感影像、农用地质量等级分等数据、外业调查数据,以及土地整治和高标准基本农田建设项目库图件与统计数据,运用熵权TOPSIS模型、建设难度指数法等,在ArcGIS与ENVI支持下,研究分析了垫江县高标准基本农田建设的耕地质量、难度、时序,以及差别化的建设分区和管理模式等。结果表明:1)综合质量上,区域空间存在地域分异性,呈现4个等级。最高Ⅳ等,主要在明月山、黄华山内侧下缘区,以及东西向中部区,呈“H”型格局;其次Ⅲ等,主要以南北中心线向两侧延伸,呈“双核”型格局;再次Ⅱ等,主要在高滩河右下侧鹤大台地区,由“双核”型转变为“单核”格局;最低Ⅰ等,主要在鹤大台地与明月山区及黄华山下缘,核心分布与Ⅱ等基本一致;2)建设难度上,呈现与综合质量较好的对应性,综合质量越高,建设难度越小。建设区划上,呈现4个区,即优先建设区、重点整治区、具备条件区和条件较差区;3)建设时序上,呈现3个时期,即近期(2016—2020年)、中期(2021—2030年)和远期(2031—2050年)。区划与时序之间,二者均呈现区域差异性;4)差别化建设上,呈现3个区,即西部明月山下缘渝巫路沿线服务于多功能农业发展区、明月山-黄华山所夹槽谷区服务于标准化粮油基地区、高滩河右岸鹤大台地为中心服务于立体循环农业区;5)差别化管理上,呈现3个类型,即立地主导型、设施主导型和区位主导型。综上所述,高标准基本农田建设时序受耕地质量和建设难度的影响,高标准基本农田差别化建设与管理应主要考虑建设区域立地条件和产业发展的模式,该文研究成果可以为垫江县高标准基本农田的建设区划工作提供参考。

Abstract:Abstract: The difficulty and timing analysis of high standard basic farmland construction is one of the prerequisites for construction planning. In order to further identify the relationship among the quality of cultivated land, the difficulty and time series of construction, the paper regarded Dianjiang County in Chongqing as the study example. The cultivated land quality, the difficulty and time series of high standard basic farmland construction in Dianjiang County, as well as the differential construction zone and management model were studied and analyzed, by adopting high resolution SPOT5 remote sensing images, agricultural land quality grade data, external survey data, and the project database of land consolidation and high standard basic farmland construction projects statistical data, using the entropy weight TOPSIS model, the construction difficulty index method, etc., and based on the support of ArcGIS and ENVI software. The results showed that: (1) from the aspect of the comprehensive quality, the regional spatial distribution was showing 4 levels obviously. The highest grade \
Keywords:high standard basic farmland  differentiation  construction difficulty  construction sequence  construction mode
