| 摘 要： | 高标准农田建设是优化农田空间布局,改善耕地基础设施,提高耕地质量和综合生产能力的重要举措。而科学合理地划定建设区域是高标准农田建设的重要环节。以河南省焦作市为例,构建了耕地综合质量评价体系,并通过层次分析法对各个评价指标赋权。再结合理想点逼近法和局部空间自相关分析对高标准农田建设分区及时序提出了方案。研究结果表明:焦作市耕地整体质量较好,且在空间分布上体现出了较强的正相关性;利用局部空间自相关分析可将耕地分为4个高标准农田建设区域。

| Abstract: | Well-facilitied capital farmland construction is an important measure to optimize the farmland spatial layout and improve the farmland infrastructure, and it also plays an important role in guaranteeing national food safety and modern agriculture development. Moreover, it could help to increase the cultivated land quality and productive capacity. Scientific and reasonable zoning of the construction area is an essential step of the construction itself. Therefore, taking Jiaozuo City, Henan Province as an example, the comprehensive quality evaluation system of cultivated land was built, and then the weight of each evaluation index was calculated by means of analytic hierarchy process (AHP). Then through coupling with technique for order preference by similarity to an ideal solution (TOPSIS) and local indicators of spatial association (LISA), some suggestions for construction of well-facilitied capital farmland zoning and timing sequence were put forward. The result showed that the overall quality of cultivated land in Jiaozuo City was good and it showed a strong positive correlation in spatial distribution. The area of cultivated land belonging to positive correlation reached 61.665% of the total cultivated land area. Besides, cultivated land quality attributes and spatial attributes were uniform. Using local indicators of spatial association, cultivated land can be divided into four well-facilitied capital farmland construction areas. According to the characteristics of different spatial autocorrelation types, the corresponding remedial measures and construction timing were put forward. With comprehensive consideration of the cultivated land in all kinds of properties, the research can provide basis for construction of well facilitied capital farmland planning. |
