In order to understand the spatiotemporal change characteristics and driving factors of landscape pattern of land use in Ruijin-Xingguo-Yudu Reigion in the past 15 years, based on the 4 phases of remote sensing images, RS and GIS technology, land use dynamics, land use transfer matrix, landscape pattern index were use to analyze the spatiotemporal evolution characteristics of land use and landscape pattern in Ruijin-Xingguo-Yudu Reigion, and 11 socio-economic factors for principal component analysis were selected to analyze their driving factors by combining with relevant statistical information and policies and regulations. The results show that forest land was the most important land use type in Ruijin-Xingguo-Yudu region, and accounted for about 69% of the total area of the study area. From 2003 to 2008, construction land had a continuous increase trend, while cultivated land had a continuous decrease trend, and grassland and waters were in a state of fluctuation. Type conversion was dominated by the mutual conversion between forest land and grassland, grassland and cultivated land, cultivated land and construction land. Cultivated land was the main source of conversion of construction land. The degree of fragmentation of the landscape in the study area was reduced, the advantages were improved, the overall diversity and balance were slightly improved, and the landscape types in the study area were balanced and diversified. The changes in the landscape pattern of land use in Ruijin-Xingguo-Yudu Region were affected to a certain extent by topography and geomorphology. The main driving factors are economic development, population growth, industrial structure adjustment, and the implementation of relevant policies and regulations.
