Abstract Land use and its landscape pattern configuration are closely related to urban development, and Land Use/ Cover Change (LUCC) profoundly impacts regional soil and water conservation and ecological security.The spatio-temporal change characteristics of land use and landscape patterns in Zhongshan City, which is an important city in the Guangdong-Hong Kong-Macao Greater Bay Area, were explored at multiple scales and levels using analytical methods such as transfer matrix and landscape pattern index based on the land use data of GlobeLand30 from 2000 to 2020. The result shows:①In the past 20 years, the overall land use in Zhongshan City showed a trend of “two increases and three decreases” in which construction land and forest land increased, and cultivated land, grassland, and water bodies decreased. Construction land has grown rapidly, while cultivated land has plummeted by nearly 50%.②In the past 20 years, each land use type has been converted to each other, which is mainly manifested in the conversion of cultivated land, water bodies, and grasslands into construction land.③The dominant landscape type of Zhongshan City has changed from cultivated land in 2000 (670.22 km2, 37.23%), water bodies in 2010 (505.15 km2, 28.06%), to construction land in 2020 (644.43 km2, 35.80%), and urban development occupies a large amount of cultivated land and water bodies. At the same time, the scope of the high-value areas of the Patch Density（PD） and Contagion index（CONTAG） of construction land gradually increased, the degree of agglomeration was enhanced, and the landscape advantages continued to expand. In the past 20 years, Zhongshan City has shown a homogenization trend of land use types with construction land replacing other land types, and the spatial heterogeneity of the landscape pattern has gradually diminished, making the task of urban cultivated land protection and ecological construction more and more severe.
