    摘要:

    以河北省涿州市为研究区,从耕地的立地条件、基础设施、空间布局、生态保护4方面构建高标准农田建设条件评价指标体系,采用层次分析法对各指标赋值,综合计算评价高标准农田建设条件,并采用物元模型对各评价条件进行综合关联度计算,结合限制因素组合法,对各限制因素进行等级划分和个数组合,通过建设条件和限制因素两方面划分高标准农田建设优先区。研究结果表明:涿州市高标准农田建设条件整体较好,其中优先划入区、适宜调入区、重点整治区、后备调控区面积比例分别为17.58%、48.60%、32.70%、1.12%,且优先划入区主要分布在码头镇、刁窝乡、豆庄乡北部以及松林店镇,适宜调入区主要分布在百尺竿镇东部、东城坊镇、义和庄乡西部、刁窝乡以及涿州市南部大部分地区,重点整治区分布在百尺竿镇、东城坊镇以及义和庄乡东部地区,呈现明显的聚集状态,后备调控区分布较少,零散分布于研究区内。研究结果可为高标准农田建设优先区合理划定提供借鉴参考。

    Abstract:

    The construction of high standard farmland is of great significance to the development of modern agriculture, ensure food security and promote the sustainable development of rural areas. It is an important prerequisite for the construction of high standard farmland by scientifically and rationally delimiting the sequence of priority areas. Taking Zhuozhou City of Hebei Province as an example, from four aspects of cultivated land site conditions, infrastructure, spatial layout and ecological protection, an evaluation index system of high standard farmland construction condition was constructed. Using the analytic hierarchy process (AHP) to evaluate the indexes of each index and comprehensively evaluate the construction conditions of high standard farmland. The matter-element model was applied to calculate the comprehensive correlation degree of each evaluation condition. Through the factor combination method, the limits of limiting factors in each evaluation unit were found, the Zhuozhou high standard farmland construction priority area was finally divided into four grades. The results showed that the construction conditions of high standard farmland in Zhuozhou City was good as a whole, the proportion of the grade 1 of priority construction was 17.58%, the proportion of grade 2 area suitable for adjustment was 48.60%, the area ratio of grade 3 area in the key construction was 32.70%, and the area ratio of reserve regulation area was 1.12%. Grade 1 and grade 2 region showed obvious outward from the center of the diffusion trend and spatial distribution had a strong continuity, suitable for large-scale, high standard farmland construction. The grade 3 area was distributed in the west of Zhuozhou City, the level of restriction factors was high and the number was large, it was a difficult area to build, and the distribution of the grade 4 was less. The research results can provide reference for the reasonable delimit and result verification of high standard farmland construction priority area.
