Abstract: Based on the current land use of Guangxi in three periods of 1995、2005 and 2015, ArcGIS, Fragstats and SPSS software were combined to quantitatively analyze the patio-temporal characteristics of cultivated land use patterns in Guangxi, reveal the differentiation laws of cultivated land use patterns in different periods and identify the main driving factors. The results showed that： ①During 1995—2015, the total cultivated land area increased in Guangxi , and the time series showed a trend of increasing first and then decreasing. There was a strong spatial coincidence between the high value center of growth rate of cultivated land in 1995—2005 and the reduction rate in 2005—2015. ② From 1995 to 2005, the newly increased cultivated land mainly came from forest land and grassland, while from 2005 to 2015, some of cultivated land was converted into forest land, grassland and construction land. ③The fragmentation degree of cultivated land landscape first increased and then decreased, and the dominance of connectivity, aggregation and dominant patches in the region first weakened and then increased. ④The evolution of cultivated land use patterns was the result of multiple factors such as terrain conditions, economic development and human intervention. In the range of different topographic relief, the change of cultivated land use had different temporal and spatial characteristics. Regional economic development, urbanization level, farmers' income level, location conditions, the proportion of the primary industry, and the number of rural population were the main driving factors for the change of cultivated land use in Guangxi.
