Analysis of Spatio-temporal Pattern Evolution and Driving Factors of Land Use in Heilongjiang Province
Using the land use data of 2000,2010 and 2020,this paper studied the land use pattern,driving factors and spatio-tempo-ral changes in Heilongjiang province based on land use transfer matrix,geographical detector and center of gravity shift model. The re-sults showed that:(1) The cultivated land decreased first and then increased,the forest area increased first and then decreased,and the area of grassland and unused land decreased gradually;Water body and construction land area gradually increased. GDP,DEM and population are the main driving factors affecting land use change in Heilongjiang province,and the interaction of each factor is nonlinear and double-factor enhancement. (2) Among all land types,the center of gravity shift distance of unused land is the largest,which is 92km to the southwest,while the center of gravity shift distance of cultivated land is the smallest,which is 12.8km to the southeast. The purpose of this study is to provide scientific reference for the sustainable utilization and management of land resources in Heilongjiang province.
