Characteristics and Driving Force of Farmland Change Based on GIS—Taking Duyun City as an Example
Using the remote sensing images of Duyun City in 2010 and 2020 as data sources,the spatial and tem-poral change characteristics of cultivated land in Duyun City were analyzed from four aspects:dynamic attitude of land use change,land use transfer matrix,spatial agglomeration degree and landscape pattern,and the driving force factors affecting the change were explored by using geographic detector in order to provide a reference for the sustainable use of cultivated land and agricultural development planning.The results show that:① From 2010 to 2020,the cultivated land area decreased by 12045.42 hm2,and the changing attitude was-2.29％,which was mainly transformed into construction land,forest land,garden land and water area.② In terms of spatial distribu-tion,it is mainly distributed in Yundong Town,Xiaweizhai,Mochong Town and Guilan Township in the southeast of the city;With the development of cultivated land area decreasing,the distribution is more scattered and broken.③ During the study period,the degree of aggregation decreased and the degree of fragmentation increased.④ Ele-vation,slope,annual average temperature,annual precipitation natural factor and population density social factor are the main driving factors affecting the spatial change of cultivated land.
