Land Use Change and Prediction in Chizhou City Based on PLUS
Taking Chizhou City as the research area,this paper analyzes the land use change in 20 years,and puts forward suggestions for regional ecological environment protection and land use optimiza-tion.Based on the land use data of 2000,2010 and 2020,the temporal and spatial variation characteris-tics of land use in Chizhou City in 20 years were quantitatively studied by land use change and PLUS model,and the land use change was simulated and predicted.The results show that forest land and cul-tivated land were the main land use types in Chizhou City in the past 20 years.Among them,forest land,grassland and unused land decreased as a whole,while cultivated land,water area and artificial surface increased as a whole.The change of land use is mainly affected by climate and environmental factors.At the same time,the combination of socio-economic factors such as population and GDP has accelerated the rapid transformation of land use types.The PLUS model can effectively simulate the land use change in Chizhou City,and has high accuracy.
