| Abstract: | This article aims to quantitatively analyze the spatial and temporal evolution characteristics of land use types in Xuzhou,and provides a basis for promoting the green development of Xuzhou City.Taking the remote sensing images from 2001 to 2016 as the data sources,the spatial-temporal evolution of land use types in Xuzhou city was analyzed by calculating the land use type transfer matrix and dynamic degree.The results shown that the total arable land in Xuzhou city decreased by 17.0663 square kilometers from 2001 to 2016,and the reduction area accounted for 2.98%of the total urban area.Construction land increased by 7.0104 square kilometers,accounting for 1.22%of the total area.The water body decreased by 26.6313 square kilometers,accounting for 4.65%of the total area,and the forest land increased by 15.7531 square kilometers,accounting for 2.75%of the total area.Grassland increased by 9.5661 square kilometers,accounting for 1.67%of the total area,and unused land increased by 11.3680 square kilometers,accounting for 1.98%of the total area.It presented that the land use types in Xuzhou city had changed significantly in the past 16 years,human interference has been increased,and the intensity of human activities should be controlled. |
