Abstract

Environmental issues occur in regions of desertification from highway construction. Before and after the road construction, it impacts the rate of sand transporting from variance of local vegetation coverage, ground properties, and soil water contents etc. This article concerns also the dune activation rooted from sand borrowing, seeking for a perturbation mechanism upon local ecology from desert road project. And the author hereby puts forward some technical requirements for its vegetation recovery. Namely, revegetation rate up to 60%, and soil water content 5% upward, give shape to weathering resistance.
