| 摘 要： | 采用联合国粮农组织开发的土地覆盖分类系统的分类体系,应用1991年与2002年的遥感影像(Landsat TM/ETM ),对江阴市1991年、2002年市域范围内聚居地斑块的格局、位序-规模特征及其动态进行了研究。结果表明:1991~2002年,江阴市城市化过程发展迅速,聚居地总面积增加160%,突出表现为小城镇的扩张,期间小城镇的面积增长量约占聚居地总增长量的47%;聚居地体系的位序-规模分布的分维数由1.253增加到1.424,显示该市聚居地体系的位序-规模分布趋于均衡。各用地类型中周转率最高的裸地斑块的总面积下降了23%,聚居地总面积的相对比例则下降了70%,反映该市城镇化的相对速度有所下降。 |

| Abstract: | Based on the land cover classification system developed by UNFAO,the habitat system of Jiangyin Jiangsu province in years 1991 and 2002 was extracted from the two scenes of Landsat imagery.With these two thematic maps,the sprawl of habitat system and their rank-size distribution patterns were studied.The results showed:(1) the urban area expanded significantly,the expansion was mainly represented as the dramatic growth of small towns,which accounted for 47% of the total habitat growth,(2) the fractal dimension of the ranksize distribution of the habitat system increased from 1.253 to 1.424,which indicated that the habitat system tended to be more uniform,(3) the ratio of bare land area and habitat descended significantly,which might indicate the deceleration of urban sprawl in Jiangyin. |
| Keywords: | Rank-size analysis Habitat system Urban sprawl Jiangyin city |
