中文摘要：

以河南省新郑市为例，基于GIS和改进突变级数模型相结合的方法测度高标准农田建设的适宜性和空间稳定性指数，并以耦合协调度模型统筹适宜性和空间稳定性，从而明确高标准农田建设的区域，在此基础上通过冷热点分析遴选高标准农田建设项目区。结果表明，研究区较为适宜开展高标准农田建设，优先建设区、重点建设区、全面整治建设区和不宜建设区的面积分别为27004．83、17040．40、4361．16、5761．55hm^2。其中优先建设区应大力发展特色优质安全高效现代农业，重点建设区以整治项目为依托提升利用效率和效益，全面整治建设区以优化耕地布局和提升潜力为主，不宜建设区应注重修复提升地力、增强防灾抗灾能力。通过冷热点分析高标准农田建设的适宜性和空间稳定性耦合协调度在空间上的联系模式，实现了快速识别高标准农田建设项目区，结合研究区实际遴选了10个高标准农田建设项目区。同时，基于障碍度模型诊断识别各项目区的主要障碍因素，从而有针对性地指导各项目区有序开展高标准农田建设活动。

英文摘要：

Well-facilitied farmland construction is an important step toward implementing the ＂storing grain in farmland＂ strategy to ensure national food security in China. Scientific zoning and project sites are important for improving grain production in an effective manner. Aiming to improve the zoning process, Xinzheng city was considered as a study area for the implementation of well-facilitied farmland construction according to the coupling coordinated degree of suitability and spatial stability. The suitability index and spatial stability index were evaluated using an improved catastrophe progression model, which avoided the problems of subjective weights and aggregated evaluation results. The results demonstrated that Xinzheng city was suitable for well-facilitied farmland construction, which was divided into four types： preferential construction, main construction, regulation construction and unsuitable construction areas, with total land areas of 27 004. 83 hm2, 17 040. 40 hm2, 4 361.16 hm2 and 5 761.55 hm：, respectively. Areas assigned with these four types should be developed according to their specific characteristics. Thus, high-quality modern agriculture needed to be developed vigorously in the preferential construction areas. The main construction areas should be project regulation. The regulation construction areas needed to focus utilized efficiently with support by on optimizing the cultivated land layout and upgrading potential. In unsuitable construction areas, efforts should be made to restore the soil productivity, improve the ecological environment for cultivated land and enhance the capacity to resist extreme conditions. Based on zoning, hot and cold spots analysis using a geographic information system was employed to analyze the spatial patterns of the coupling coordination degree, and 10 project regions were selected accurately from these hot spot regions. Furthermore, the main obstacles in each project region were diagnosed to identify the next steps for development in Xinzheng city.
