摘要
基于ArcGIS 10.3软件,运用耕地压力指数和重心模型,分析1985—2018年河南省耕地压力指数的动态变化及空间分布趋势,探究耕地压力与经济发展的时空耦合关系。结果表明:1985—2018年河南省耕地压力指数呈逐渐下降趋势,由0.957下降到0.624;河南省耕地压力与经济发展联系密切,耕地压力指数与GDP、人均GDP的平均地理联系率在0.79以上,且三者的重心移动轨迹大体保持一致;河南省耕地压力与经济发展空间关联性存在区域性差异,且耦合类型滞后期和磨合期居多。
Based on ArcGIS 10.3 software,using cultivated land pressure index and gravity center model,this paper analyzes the dynamic change and spatial distribution trend of cultivated land pressure index in Henan Province from 1985 to 2018,and explores the time-space coupling relationship between cultivated land pressure and economic development.The results show that:The cultivated land pressure index in Henan Province shows a gradual downward trend from 0.957 to 0.624 during 1985—2018;The cultivated land pressure is closely related to economic development in Henan Province,and the average geographic relationship between cultivated land pressure index and GDP,per capita GDP is more than 0.79,and the center of gravity of the three is basically the same;The cultivated land pressure and spatial relationship of economic development in Henan Province are regional,the coupling type is mainly in late lag and running in period.
