摘　　要：基于甘肃省1998-2003年土地详查与变更调查数据,采用计量地理模型和空间分析方法,对甘肃省及省内各地区的土地利用的数量结构和空间格局现状及其变化进行了定量分析。结果表明：①甘肃省现状土地资源具有明显的地域差异,这种差异与其所处的地理位置、地形地貌、经济水平等密切相关;②土地利用结构的多样性和土地利用组合类型数由西向东、由北向南依次递减,土地利用结构的集中度则恰好相反;③近5年来土地利用总体程度下降,信息熵略有增加,土地利用趋于无序性。图4,表3,参9。Based on the detail survey data and change data of land use from 1987 to 2003, the quantitative structure and spatial pattern of land use in Gansu province and its administrative areas were analyzed by applying the GIS technology and some others quantitative geography models. The result indicated that： （1）there were obvious regional differences in the land use structure among the cities, which were determined by geographical locations, topography, economic levels, etc; （2）the regional change of land use structure in the study area showed the following regular patterus：the structural diversity and composed types of land use decreased by degrees from the west to the east and from the north to the south, but the centrality of land use structure was on the contrary; （3）the land use degree decreased as a whole during the last 5 years, but the information entropy increased slightly, which indicated that the land use tended to randomness.
