摘要
In view of rare vegetation in Turpan-Hami Basin, the authors utilized the remote sensing technique to extract and combine brightness, greenness and wetness indices. The results can reflect the transpiration intensity, vegetation degree and soil moisture as well as spatial distribution of drainage patterns. Through an analysis of the metallogenic hydrodynamic conditions of the study area, three districts were distinguished, i.e., supply district, runoff district and drainage district.
