    摘要:

    高标准农田建设是保护优质耕地,保障粮食安全的战略部署,合理规划建设时序和空间布局是科学、高效进行高标准农田建设的前提。以河北省涿州市为研究区,按照国家对高标准农田建设区域的基本要求,构建了耕地综合质量评价指标体系,以规则网格为评价单元,基于TOPSIS模型对高标准农田建设优先度进行了综合评价计算,并采用热点分析方法划定了高标准农田建设一级优先区、二级优先区和不宜建设区。研究结果表明:涿州市中部和西南部区域耕地立地条件较优,基础设施较好,适宜建设高标准农田,列入一级优先建设区和二级优先建设区,面积占比分别为38.4%和31.8%;西部和东部部分乡镇不宜建设高标准农田。研究结果可为高标准农田建设优先区选择提供指导,为下一步的整治方向提供依据。

    Abstract:

    High-standard farmland construction is a strategic deployment to protect the high quality cultivated land and ensure food security. It is a prerequisite for scientific and efficient construction of high-standard farmland to set rational planning of construction sequence and spatial layout. According to the requirements of high-standard farmland construction, firstly, an index system was established to response to cultivated land comprehensive quality. Secondly, TOPSIS model was chosen to evaluate the high-standard farmland construction priority in the grid environment. Thirdly, hotspot analysis method was adopted to zone high-standard farmland construction priority areas into top priority areas, the secondary priority areas and the unfavorable construction areas. The results showed that it was suitable to construct high-standard farmland in the central and southwestern areas of Zhuozhou City, where cultivated land site condition and infrastructure condition were better. These areas were zoned into top priority construction areas and the secondary priority areas, with area proportions of 384% and 318%. It was unsuitable to construct high-standard farmland in some township of western and eastern regions. The results can provide scientific guidance for zoning high-standard farmland construction priority areas and indicate the direction of land consolidation.
