摘　　要：采用定性与定量相结合的方法对滑坡要素进行了深入分析。将滑坡要素划分为空间要素、时间要素和岩土性质要素3个方面,并分别讨论它们与遥感影像空间分辨率、时间分辨率和波谱分辨率的关系。首先对各滑坡要素进行了定性分析,然后提出了判识滑坡空间要素的定量依据;提出了通过遥感影像计算滑动速率的公式,以此作为按照时间分辨率选择遥感数据的依据;最后提出为判识岩土性质要素应采用高波谱分辨率遥感影像的观点。The paper analyzed the elements of landslide deeply by the combination of qualitative and quantitative methods.The elements of landslide are divided of three species： space elements,time elements and the nature elements of rock and soil,and their correlations with the special resolution time resolution and spectral resolution of the remote sensing images were discussed separately.First,the paper analyzed qualitatively of the landslide elements.Then,proposed a quantitative basis for the identification of space elements of landslide and a formula to calculate the slip rate by the remote sensing images,based on which the remote sensing data by the time resolution were chosen.Finally,the paper proposed that hyper-spectral remote sensing data were needed to identify the nature elements of rock and soil.
