摘要

Based on the land use data of Yuyang District in 2000, 2010 and 2020, using the land use transition matrix, the temporal and spatial change characteristics of land use in Yuyang District were analyzed. The results showed that the land use type in Yuyang District from 2000 to 2020 was mainly grassland, of which the grassland area in 2020 was 5290.1 km^2, accounting for 58.38% of the total area of the study area. In the past 20 years, the absolute change of land use types in Yuyang District is: grassland ＞ construction land ＞ cultivated land ＞ wetland ＞ forest land ＞ shrub land ＞ bare land ＞ water body. The land and bare land first increased and then decreased, and the area of water and wetland decreased first and then increased. The reduction of grassland and wetland area is mainly affected by human factors.
