安阳市土地利用变化特征及驱动因素分析

Characteristics of land use change in Anyang and its driving factor analysis

本研究以河南省安阳市为例,以GlobeLand 30数据为基础,使用土地利用转移矩阵、土地利用动态度、标准差椭圆等方法,并结合地理信息系统(GIS)空间分析技术,探究安阳市2000—2020年来土地利用的变化规律及驱动因素,为安阳市土地利用可持续发展提供一定的现实依据。结果表明:①2000—2020年安阳市主要以耕地为主,建设用地和耕地面积变化的趋势最是明显;②2000—2020年动态度变化较大的分别为水域和建设用地;③2000—2020年土地利用类型的排序大致为耕地>建设用地>林地>草地>水域;④2000—2020年土地利用类型在空间上呈现逐渐扩张的趋势,整体上表现出从东北向西南方向集中分布的迹象;⑤政策因素、人口因素和经济因素是造成安阳市土地利用变化的驱动因素。

Taking Anyang city of Henan province as an example,based on GlobeLand 30 data,this study used methods such as land use transfer matrix,land use dynamic behavior,standard deviation ellipse,and combined with geographic information system(GIS)spatial analysis technology to explore the change law and driving factors of land use in Anyang city from 2000 to 2020.It provides some realistic basis for the sustainable development of land use in Anyang city.The results showed that:①From 2000 to 2020,Anyang city was mainly cultivated land,and the change trend of construction land and cultivated land area was the most obvious.②From 2000 to 2020,the dynamic attitude of water and construction land changed greatly.③From 2000 to 2020,the order of land use types was roughly cultivated land>construction land>forest land>grassland>water area;④Land use types showed a spatial expansion trend from 2000 to 2020,with a concentrated distribution from northeast to southwest.⑤Policy factors,population factors and economic factors are the driving factors of land use change in Anyang city.
