Analysis of Land Use Type Changes in Yulin City in the 21st Century

Abstract

Using remote sensing monitoring data of land use/land cover in China in 2000 and 2020, this study explores the changes in land use types in Yulin City through the land use transfer matrix. The results indicate that the main types of land use in Yulin City are grassland, cultivated land, and unused land. From 2000 to 2020, the order of absolute changes in the area of land use types in the study area is: unused land>grassland>construction land>cultivated land>forest land>water area, and its changes are closely related to national ecological policies; The area of construction land has significantly increased after 2000, which is consistent with the process of urbanization development; The continuous decrease in water area is mainly influenced by natural factors. The changes in land use types in Yulin City are influenced by both natural and social factors, with ecological policies and urbanization development dominating.
