| Abstract: | Lanzhou Valley Basin is composed of two smaller diamond-shaped basins striking from NW to SE and including 6 river terraces.
The lower terraces remaining even and smooth are main sites for city buildings. The main function of Lanzhou urban settlement
is a ferry and transport centre. Lanzhou used to be an important crossing site and post on the “silk road”, and then became
a transport and trade centre in Northwest China. In the middle part of the 17th century, Lanzhou became the capital of Gansu,
a new province. The development process of Lanzhou urban settlement indicates that urban settlement is a system consisting
of natural environment and human society based on the former. |
