摘　　要：该文分析了城市景观及城市景观元素的基本特征,利用计算机视觉分析技术,对高分辨率卫星影像上的城市景观元素的基本特征(包括统计特征和纹理特征)分别提出了不同的计算方法,并结合计算结果,对不同的城市景观元素的特征进行分析。结果表明,利用高分辨率卫星影像,可以对城市景观元素进行很好的描述和分析。A new access to the research of urban landscape has been provided with the development of remote sensing technology on high spatial resolution. At the beginning of this paper,the urban landscape and the characteristics of urban landscape elements are analyzed, and then by machine version different methods are provided to compute and analyze the basic characteristics (including statistic and texture) of landscape elements in urban areas of high-resolution satellite image. The result shows that it is possible to describe and analyze the urban landscape elements satisfactorily by using high-resolution satellite image.
