【摘要】：[目的]"十三五"期间国家重点推进高标准粮田建设与实施,河南省同时处于粮食生产核心区与中原经济区下,肩负着保证粮食安全与实现中部崛起的双重重担,基于"五化"要求研究高标准粮田时空布局优化有其现实意义。[方法]基于AHP方法原理构建布局优化指标体系,依据熵权值法与优化方法获取权重,在Arc GIS软件中实现地块平均布局水平测算,并按照规划要求相应调整,运用综合排序优选法与逼近理想点法进行鹤壁市高标准粮田时空布局优化。[结果]鹤壁市不存在高标准粮田布局劣等地,布局重心处于浚县与淇县;两县的空间布局优化结果显示出更高的集中连片性,平均地块面积是优化之前的1.466倍;两县的时序布局优化结果有利于提高建设效率,达成"初期试探摸索-中期大量投建-远期稳固提升"目标。[结论]基于"五化"视角的高标准粮田时空布局优化为今后高标准粮田区土地利用优化配置以及各项利用规划提供了参考与依据。
[Abstract]:[objective] during the 13th Five-Year Plan period, the state focused on promoting the construction and implementation of high standard grain fields. Henan Province is under the core region of grain production and the Central Plains Economic Zone at the same time, shouldering the double burden of ensuring food security and realizing the rise of the central region. It is of practical significance to study the optimization of space-time layout of high-standard grain fields based on the requirements of the five-year transformation. [methods] based on the principle of AHP method, the index system of layout optimization was constructed, the weight was obtained by entropy weight method and optimization method, and the average layout level of plots was measured in Arc GIS software, and adjusted according to the planning requirements. The optimization of space-time layout of high standard grain fields in Hebi City was carried out by using the comprehensive sorting optimization method and the approaching ideal point method. [results] there was no inferior distribution of high standard grain fields in Hebi City, the center of gravity of the layout was in Junxian and Qi County, the results of spatial layout optimization of the two counties showed a higher concentration and continuity, and the average land area was 1.466 times of that before the optimization. The optimization results of the temporal layout of the two counties are conducive to improving the construction efficiency and achieving the goal of "initial trial and groping, large investment and construction in the medium term, long-term steady promotion". [conclusion] the optimization of space-time layout of high-standard grain fields based on the "five changes" provides a reference and basis for the optimal allocation of land use and various utilization plans in the future of high-standard grain fields.
