摘要
建设高标准基本农田是保障粮食安全的重要途径,通过研究高标准基本农田建设布局,可以使其布局更科学合理。以河北省宁晋县为研究区,分别从耕地质量和高标准基本农田建设适宜性两个维度进行了评价,并采用四象限模型对其耦合,划分了四种类型区。结果表明:"低质量—低适宜性"区主要分布于唐邱乡北部、纪昌庄乡等地区,不适宜基本农田建设;"高质量—低适宜性"区主要分布于道路和城镇周边,受城镇扩张和道路影响较大,应加强农田保护和基础设施建设;"低质量—高适宜性"区主要分布在中北部和南部地区,主要受土壤剖面构型和灌溉条件的限制,应注重提升耕地质量;"高质量—高适宜性"区分布最广泛,占耕地面积的44.50%,应注重优化田块布局,加快田间路网建设,发展现代化农业。研究方法和结果可为县域高标准基本农田建设提供科学依据。
The construction of high standard basic farmland is an important way to protect the food security. We can make it more scientific and reasonable layout by studying the high standard basic farmland construction layout. Taking Ningjin County of Hebei Province as an example, we evaluated the cultivated land quality and high standard basic farmland construction suitability, respectively, coupled to it using the four quadrant model, and divided farmlands into four kinds of type. The results show that ＇low quality-low suitability＇ mainly distributes in the north of Tangqiu, Jichangzhuang, etc, these areas are not suitable for construction of basic farmland; ＇high quality-low suitability; mainly distributed nearby the roads and towns, which was greatly influenced by expanding towns and roads, and the farmland protection and the infrastructure construction should be strengthened~ ＇low quality-high suitability; mainly distributed in the northern and southern regions, which was mainly affected by the soil profile configurations and limited irrigation conditions, attention should be paid to improve the quality of cultivated land; ＇high quality-high suitability; distributed the most widely, which accounted for 44.50% of the cultivated land area, great attention should be paid to the optimized field block layout, speeding up the field road network construction and developing modernization agriculture. These results can provide scientific basis for the construction of high standard basic farmland in this county.
