【摘要】：基于永久基本农田概念、内涵和划定要求,提出了县域永久基本农田的定量评价模型与划定方法,并以河北省定州市为例进行示范验证。定量评价模型包括自然禀赋条件、基础设施条件、社会经济条件和区位条件4方面12个指标,并在改进连片度和田间道路密度计算方法的基础上进行综合评价。根据综合评价结果,将定州市耕地划分为优先保护型(≥76.00)、重点保护型(68.91~76.00)、适宜调控型(60.00~68.91)和后备整治型(0~60.00)4种类型,其中:优先保护型(28 389.22 hm~2)集中分布在城区及镇政府周边,是定州市重要的粮食生产基地;重点保护型(39 084.13 hm~2)主要分布在庞村镇、大鹿庄乡、杨家庄乡等,是永久基本农田的重点建设区域;适宜调控型(16 831.95 hm~2)分布较为分散,主要分布在砖路镇、赵村镇、西城区等,未来通过差别化土地整治再适当调为永久基本农田;后备整治型(5 126.82 hm~2)零散分布在西城区、北城区、息冢镇等,目前不适宜划作永久基本农田。研究结果可为定州市永久基本农田划定与相关规划提供依据。
[Abstract]:Based on the concept, connotation and demarcation requirements of permanent basic farmland, a quantitative evaluation model and method for defining permanent basic farmland in county area are proposed, and the demonstration and verification are carried out in Dingzhou City, Hebei Province. The quantitative evaluation model includes 12 indexes including natural endowment condition, infrastructure condition, socio-economic condition and location condition, and comprehensive evaluation is carried out on the basis of improving the calculation method of connectivity and field road density. According to the comprehensive evaluation results, the cultivated land in Dingzhou City was divided into four types: priority protection type (鈮，
