| 摘 要： | 由于城市具有典型的非均质性及构成城市的要素较小, 因此, 城市生态系统遥感与自然生态 系统遥感有显着的差异。本文讨论了影响城市遥感诸因素, 如人工物质的光谱特性、混合像元、 霾因子、边缘锐度及摄影死角等问题, 此外, 就传感器、像片比例尺、分辨率、旁向重叠率、时相 等的选择原则也作了论证。

| Abstract: | Since a city has a typical--homogeneity and its elements are small, the differences between the remote sensing of the urban ecosystem and the natural ecosystem are remarkable. The factors affecting urban remote sensing such as spectral signatures of artificial materials, mixed pixels, the haze factor, the edge sharpness and photographical blind angles are discussed in this paper. The criteria chosen for Sensors, photo scale, resolution, lateral overlap and temporal are demonstrated as well. |
