Harbin is located on the fertile black soil of the Northeast Plain. As an important grain-producing area in my country, its land use situation has received great attention from my country’s grain policy. This study took Harbin as the research area and analyzed the land use situation from 2000 to 2020. Through the study of land use structure changes, dynamic characteristics and the transformation relationship between types, the following main conclusions were drawn: (1) Cultivated land and forest land are the main land use types, accounting for about 44% and 43% respectively. The spatial distribution shows regional differences and concentrated distribution characteristics. (2) The overall dynamic degree of comprehensive land use first increased, then decreased, and then increased. It was 0.19% during the period 2000~2020. The order of the single land use dynamic degree according to the absolute value of the dynamic is unused land > water area > grassland > construction land > forest land > cultivated land. (3) The total conversion area from 2000 to 2020 is 3918.57 km2. The transfer-out area of cultivated land, forest land, and water area is larger than the transfer-in area, and the total area is decreasing; the transfer-in area of grassland, construction land, and unused land is relatively larger than the transfer-out area, and the total area is on an upward trend. %K 土地利用变化， %K 动态度， %K 转移矩阵， %K 哈尔滨市
