Analysis of Spatio-temporal Evolution and Influential Factors of Land Use Dynamics in Guangxi
To explore the spatiotemporal evolution pattern of land use dynamics in Guangxi,this paper analyzed the land use dynamics in Guangxi from 2000 to 2020 by using kernel density estimation and standard deviation ellipse.The results showed that:①The land use dynamics in Guangxi increased year by year,and the land use dynamics in all counties and districts increased to more than 4%from 2015 to 2020;②There were differentiation phenomena in different periods within each region,but the regional differences gradually converged,and the land use dynamics became more balanced;③The distribution center of land use dynamics began to transfer from Xingbin District of Yingbin City,and finally gradually approached the geometric center of Guangxi;④ The restriction of natural conditions caused the geographic pattern of land use dynamics in Guangxi,which was"high in the south and low in the north".The acceleration of population gathering and urbanization,and the adjustment of industrial upgrading made the overall land use dynamics show a continuous upward trend.The implementation of the poverty alleviation strategy during the 13th Five-Year Plan period made the overall land use dynamics in Guangxi tend to be balanced.
