【摘要】：从耕地的自然条件、利用情况和经济水平出发,结合耕地的空间属性,借助空间自相关性分析方法,提出了科学、合理的耕地保护分区方法。首先运用全局空间自相关的方法,探究高平市耕地质量在空间上整体的分布情况,以便进行下一步更细致的分析;再运用局部空间自相关的方法,以耕地质量指数为变量,探究高平市耕地质量的空间分布规律,最终基于综合质量的分析结果提出耕地保护分区方案。研究结果表明:整体分析显示,高平市耕地的自然条件、利用情况和经济水平皆表现出显著聚集性;局部分析得出,高平市耕地从自然条件、利用情况和经济水平3方面呈现出一定的规律性,HH(高-高)型和LL(低-低)型耕地表现为聚集分布;HL(高-低)型和LH(低-高)型耕地呈零星分布。最终从耕地的3方面分别进行局部分析,并依据3个局部分析结果组合,结合实际,提出耕地保护分区的方法及思路。
[Abstract]:Based on the natural conditions, utilization and economic level of cultivated land, combining the spatial attribute of cultivated land, and with the aid of spatial autocorrelation analysis method, a scientific and reasonable method of cultivated land protection zoning is put forward. First of all, using the method of global spatial autocorrelation to explore the overall distribution of cultivated land quality in Gaoping City in order to carry out further detailed analysis; then using the method of local spatial autocorrelation to take the cultivated land quality index as a variable. The spatial distribution law of cultivated land quality in Gaoping city is studied. Finally, based on the analysis results of comprehensive quality, the zoning scheme of cultivated land protection is put forward. The results show that the natural conditions, utilization and economic level of cultivated land in Gaoping City are significantly aggregated, and the local analysis shows that the cultivated land in Gaoping City is derived from the natural conditions. In terms of utilization and economic level, HH (high) type and LL (low) type cultivated land were distributed sporadically in HL (high low) type and LH (low high) type cultivated land. Finally, the local analysis is carried out from three aspects of cultivated land, and according to the combination of three local analysis results, combined with the actual situation, the method and thought of cultivated land protection zoning are put forward.
