作为城市生态系统的重要组成部分之一，绿地起着尤为重要的作用。然而传统的调查方法不仅费时费力，且动态更新较为困难。本文以兰州市区为例，采用遥感数据Landsat 8 OLI影像结合目视解译、植被指数和混合像元分解方法提取绿地信息，初步比较了三种方法的分析结果。最后据此分析兰州市绿地的空间分布特征，为城市的发展提供有益的建议。

As part of the urban ecosystem, green land plays a very important role. However, traditional methods of investigation are not only time-consuming, but also dif icult for dynamic update. This paper used remote sensing image data from Landsat 8 OLI combined with visual interpretation、vegetation index and pixel unmixing to extract green space and evaluate the accuracy. Final y, we analyzed the spatial distribution of green space of Lanzhou and provide useful suggestion for the city's future development.
