| 中文摘要 | 基于1996～2004年土地详查与变更调查数据，采用计量地理模型，对酒泉市及市内各县区的土地刊用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酒泉市土地资源具有明显的地域差异，土地利用结构的多样性由东向西、由南向北依次递减，集中度则恰好相反；②各县区土地利用类型的空间分布及其时间变化均具有不均衡性，在空间尺度上，园地分布最不均衡，未利用地分布相对均衡；在时间尺度上，园地、林地、牧草地和交通用地的分布趋向均匀，其余土地利用类型趋向分散；（参近8年来土地利用总体程度下降，信息熵减少，土地利用趋于有序性。 |
| 英文摘要 | Based on the detailed survey data and change data of land use from 1996 to 2004, the quantitative structure and spatial pattern of land use in Jiuquan City and its administrative areas were analyzed by applying the quantitative geography models. The result indicated that： （1）there were obvious regional differences in the land use structure among the counties, which were determined by geographical locations ,topography,economic levels, etc. The regional change of land use structure in the study area showed the following regular patterns ：the structural diversity and composed types of land use decrease by degrees from the east area to the west area and from the south area to the north area, but the centrality of land use structure is on the contrary; （2） the land use degree decreased as a whole during the resent 8 years,and the information entropy also decreased slightly, which indicated that the land use tended to regular; （3）The distribution of different land use types is temporally and spatially unbalanced. The most unbqalanced lands were garden lands ,while the unused land were balanced. With time,the unbalanced degree of the garden lands,forestry lands,grasslands and traffic lands decreased, while that of the water areas, cultivated lands, residential areas and unused lands exhibited an opposite trend. These results can provide scientific basis for land structure adjustment and land resources utilization. |
