安徽省耕地非农化的时空演变特征及迁移路径

Characteristic of Spatiotemporal Evolution and Migration Path of Cultivated Land Non-agricultural Conversion in Anhui Province

研究目的:为有效应对安徽省耕地非农化问题,探究县域耕地非农化的时空演变特征及迁移路径。研究方法:以1990-2020年共7年的安徽省LUCC数据为基础,借助ArcGIS软件,引入重心模型、标准差椭圆模型,探究耕地非农化的时空演变及迁移路径。研究结果:1990-2020年期间,安徽省县域耕地非农化重心空间路径表现为“y”型形态,呈现出先远离后靠近的态势。研究结论:揭示了安徽省县域耕地非农化近30年来的时空演变及迁移趋势,以期为政府部门掌握耕地非农化趋势提供一定参考,从而更好保护耕地。

Research purpose:In order to effectively address the issue of farmland conversion in Anhui Province,this article explores the spatiotemporal evolution characteristics and migration paths of farmland conversion in counties.Research method:Based on 7 years of LUCC data from Anhui Province from 1990 to 2020,this article uses ArcGIS software to introduce the center of gravity model and standard deviation ellipse model to explore the spatiotemporal evolution and migration path of farmland conversion.Research results:During the period from 1990 to 2020,the spatial path of the non agricultural transformation center of cultivated land in counties of Anhui Province showed a"y"shape,showing a trend of first moving away and then approaching.Research conclusion:The conclusion reveals the spatiotemporal evolution and migration trend of farmland conversion in counties of Anhui Province in the past 30 years,which provides a certain reference for government departments to grasp the trend of farmland conversion and better protect farmland.
