Abstract:
It is a key problem to define the index system of the region division for desert highway. During the natural region division of the desert highway in China, the topography, climate and ecology of desert were selected as the reflection of the impact of environmental parameters for highway projects. Based on the commensurable theory, the desert comprehensive state index which combines the effects of the environmental parameters was established. Regarded the desert comprehensive state index as the dominant index, and regarded the sandbank height, the sand and wind strength, the vegetation overlay and the annual temperature variety as the auxiliary index, the index system of natural division for desert highway in China are finally made. 3 tabs, 5 figs, 8 refs.
