Abstract: Based on Landsat TM image data and socio-economic data from 1998 to 2018 in Hulan district of Harbin city, the characteristics of land use change in Hulan district of Harbin city during 1998—2010, 2010—2018 and 1998—2018 are analyzed scientifically and systematically by means of ENVI, ArcMap and other software, using methods of supervisory classification, land use change model and canonical correlation analysis. The results show that: in the past 20 years,the change of the whole land cover area in Hulan district of Harbin city reflects the change pattern of land use with the increase of residential land and water area, a downward trend in cultivated land area, and the decrease of grassland and woodland. Moreover, the change speed and range in the first 8 years are greater than that in the last 12 years. The main reasons for the change of land use types in Hulan district can be divided into natural factors, socio-economic factors and population factors.

Key words: land use, coverage change, driving analysis, remote sensing, Hulan district of Harbin city
