摘  要:
用3段波双时象定性定量相结合的方法建立TM卫片的地面解译标志,解决了两方面问题,(1)利用冬季时相的TM卫片配合野外调查资料研究地貌和各种土地利用类型清晰、快捷、准确、经济。(2)利用夏季时相TM片上的光密度反射值与实地植被盖度相对应,建立二者之间回归方程C=21.36L~(2.39),解决了解译过程中植被盖度的定量问题。

摘  要:
By using the methods of 3 frequency channels with double time features,the ground interpret marks of TM pictures have been found and the follow two problems have been solved: one is that studying topography and various soil use types combained using TM pictures in winter time with geography survey data could obtain a clear, quick, precise and economic result. Another is that light density reflect values of summer time TM pictures were related to local plant coverrates could found the formula as follows: 1 = 21. 36 L~(2.39).
