Qiqihar is located in the northeast of China, located in Songnen Plain, with fertile land, suitable for agricultural production and diverse ecological environment. It is known as “the world’s great wetland, the hometown of cranes in China”. Its land use situation is widely concerned by academic circles. This study takes Qiqihar City as the research area and analyzes the land use situation from 2000 to 2020. Through the research on the change of land use structure, dynamic characteristics and the transformation relationship between types, the following main conclusions are drawn: (1) Cultivated land is the main land use type, accounting for about 70%, and its spatial distribution shows the characteristics of regional differences and centralized distribution. (2) The overall dynamic attitude of comprehensive land use is on the rise, and it is 0.31% from 2000 to 2020. The order of single land use dynamic degree is water area > unused land > grassland > woodland > construction land > cultivated land. (3) The total transfer area from 2000 to 2020 is 42246.48 km2. The transfer-in area of forest land, grassland and water area is smaller than the transfer-out area, and the total area is reduced; The transfer-in area of cultivated land, construction land and unused land is larger than the transfer-out area, and the total area increases. %K 齐齐哈尔市， %K 土地利用， %K 转移矩阵， %K 动态度
