This study analyzed four periods of land use raster data in 1992, 2002, 2012, and 2022, utilizing software tools such as ArcGIS 10.7, Fragstats 4.2, and the PLUS model. The objective was to identify the characteristics of land use changes in the major urban areas of Jingzhou City, specifically in Jingzhou District and Shashi District, over the past 30 years. Additionally, the analysis incorporated 14 influencing factors to determine the primary influencing factors of various land use changes. The findings indicated that: ① the area designated for construction within the study region had consistently expanded in a distinct north-easterly direction from 1992 to 2022. The primary increase in construction land was attributable to the decrease in cultivated land. Despite a decrease in its proportion, cultivated land remained the predominant landscape throughout this period. ② The expansion of construction land led to a reduction in the spatial aggregation of various land types, an increase in fragmentation, a decrease in heterogeneity, and a rise in the complexity of land shapes. ③ Socio-economic factors, including distances to primary and secondary roads, highways, and natural elements such as precipitation, DEM, and distance to water systems, were the primary driving factors influencing various land use changes. Overall, socio-economic factors serve as the principal driving force of changes in land use landscape patterns in the study area. |
