Abstract

In recent years, it was one of the currently hot issues, which study the evolution of river way and hydro-system using 3S technology. Aerial photos, TM/ETM+ and SPOT5 imagery were offered to study the evolution of riverway in QingKou region. Automatic detection for change information method such as spectral variation method and false color composite method were used to detect change information, the results showed that the former method was better. Five Rivers in Qingkou Region were selected for our research, change information such as length and width was extracted separately. On this basis, the driving factors of evolution were analyzed. The riverway gradually become steady due to effective river rectification, the influence caused by man-made factors was greater than natural factors in the evolution.
