Suitability evaluation of urban terrain in China

[摘要] To clarify the terrain characteristics of Chinese cities, three terrain parameters that altitude, relief and slope are selected to be analysed. Based on these factors, we make a classification of urban landforms and then compare the differences of urban terrain using the classification results. In conclusion, firstly, it is in a micro scale that the terrain of built-up areas has similar characteristics. Secondly, a method to evaluate the suitability of urban terrain in China is proposed and the suitability evaluation of terrain around built-up areas is realized. Finally, statistical data shows that Chinese urban expansion potentials are all considerable except for urban areas in high altitude mountain.
