Spatial-temporal evolution and influencing factors of cultivated land in karst mountainous area
s:The spatial-temporal evolution and influencing factors of cultivated land in the karst mountainous area were analyzed us-ing kernel density and transfer matrix methods with cultivated land data of Zhenfeng County,Guizhou Province from 2010 to 2020 as the object.The results showed that from 2010 to 2020,the cultivated land area decreased from 56 754.16 hm2 to 39 715.85 hm2,a total decrease of 17 038.31 hm2,and the degree of fragmentation increased.During the study period,cultivated land was mainly con-verted into forest and garden land,which mainly occurred in the central part of the study area around Baiceng Township,Lurong Town-ship,and Lugong Township,followed by the continuous occupation of cultivated land by construction land,which accelerated the re-duction of cultivated land area.Natural and social factors jointly influenced the distribution of cultivated land and its changes,and cul-tivated land was mainly distributed on slopes of 6°to 25°and within 100 m of the buffer zone of roads and settlements.
