摘　　要：以大庆市1987年和2005年SPOT遥感影像为基础数据,采用GIS和计量地理模型对大庆市土地利用动态变化进行分析。研究结果表明:1987～2005年大庆市未利用地、建设用地、耕地和林地呈增加态势,其他地类减少;土地利用向无序方向发展,土地利用多样性增加,各土地利用类型呈均匀分布;土地利用程度下降,土地利用整体处于调整期。Taking the SPOT remote images of Daqing city in 1987 and 2005 as basic data source, the dynamic changes of land use in Daqing city were analyzed by the methods of GIS and quantitative geography model. The results indicate that from 1987 to 2005, the unused land, construction land, arable land and wood land presented an increase trend, and the other land types decreased; the land use developed to the trend of random disorder, meanwhile, the diversity of land use had increased and the type of land use distributed uniformly; the land use degree had decreased, and the land use was in adjustment phase on the whole..
