摘要

不透水面是城市的基质景观和地表覆被的典型特征，主导着城市景观格局与过程，也是城市环境变化的主要因素之一。利用Landsat ETM

卫星影像探测获得昆明市2000-2010年3个时相的主城区不透水面信息，采取修正的归一化水体指数进行水体的剔除，排除水体对不透水面提取精度的影响。利用城市不透水面与植被覆盖度负相关的联系，进而提取研究区不透水面信息。所提取信息精度较高，能较好地反映出城市扩张的趋势，以及对城市周边生态环境的破坏程度。研究结果表明，昆明市主城区的不透水面面积在近10a间明显增加，城市不断地向郊区扩张，极大地影响了周边生态环境，郊县植被覆盖率严重下降。

Abstract

As city's matrix landscape，impervious surface dominates urban landscape patterns and processes.It is not only a typical characteristic of urban surface cover

but also one of the main factors in the change of urban environment.This paper uses Landsat ETM+ satellite images to detect three-phase impervious surface information of the Kunming City from 2000 to 2010.We extract water information by using modified normalized difference water index and exclude the impacts of water on impervious surface extraction accuracy.Based on the negative correlation between urban impervious surface and vegetation coverage

we extract impervious surface information of the study area and obtain higher extraction accuracy.This study can better reflect the trend of urban expansion and the damage extent to the periurban ecological environment.Results from the study showed that impervious surface area of the study area increased so fast in the last ten years.The city is continuing to expand to the suburbs

which has a great impact on the surrounding ecological environment and result in a serious decline in the suburban vegetation cover.
