| 摘 要： | 基于四期遥感影像数据(TM、ETM、WFV2)对城市建成区进行调查,研究1990年以来长春市的扩展情况,并结合统计年鉴资料,对长春市城市土地利用效率进行研究。结果表明:1990—2013年长春市建成区的面积持续增加,除东北方向之外,其他方向扩展明显;长春市的发展方式以外部扩张与内部填充发展交替进行,并且城市建成区形状简单,土地利用受城市规划影响较大,城市向着有序的方向发展,有利于城市土地利用效率的提高;1990—2012年城市土地利用效率虽有波动,但整体呈上升趋势。

| Abstract: | On the basis of the remote sensing image (TM，ETM，WFV2) of four periods， the author investi- gated the urban expansion and studied the urban land use efficiency of Changchun City since 1990，combining with statistical yearbook data． The results showed that the urban built- up area continued to increase from 1990 to 2013 and expanded to all directions except the northeast direction． The development of Changchun City alternated exter- nal expansion and internal filling and the shape of the city was simple． The land use was influenced by urban plan- ning obviously and the city developed in an orderly way，which was beneficial to the improvement of the urban land use efficiency． The urban land use efficiency showed fluctuation but the trend was upward overall from 1990 to 2012． |
