| 摘 要： | 基于三期遥感影像数据( MSS、ETM、CBERS) 对城市建成区的面积进行了调查，研究30 多年来东北三省城市的扩展情况，并且结合NDVI 数据，对研究区范围内的植被覆盖情况进行了研究。结果表明: 1976-2000 年、2000-2007 年两个阶段，城市建成区的面积持续增加，年均扩展率由 5. 10%增加至6. 32%，扩展强度比较显著的区域主要分布在哈大交通经济带上; 研究区范围内东部的植被覆盖情况明显好于西部，NDVI 均值随与城市距离的增加而提高。

| Abstract: | Based on the remote sensing images（MSS,ETM,CBERS）for three periods,the authors investigate the urban buildi-up area,and study the expansion in three provinces of Northeast China in the past 30 years and vegetation coverage,combining with the NDVI data.The results showed that the urban build-up area continue to increase in 1976-2000 and 2000-2007,the annual mean expansion rate increased from 5.10% to 6.32%,the notable area of expanding strength mainly distributed in Harbin-Dalian traffic economic belt;the vegetation coverage in the east was better than the west within the scope of the study areas,and NDVI mean raised with the increase of urban distance. |
