[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.
