A Study of Vegetation Restoration Technology in Arid-hot Valleys Based on the Principle of Water Self-supporting of Vegetation Community

In this paper,a new technology of vegetation recovery was proposed based on the principle of water-self supporting of vegetation community. The core of the technology was to make full use of the instinct of the rehabitaion and adaption of vegetation to the environment,and on the basis of species selection,soil improvement and underlying surface improvement were done to create a proper living conditions for the survival of the vegetation so that the vegetation could give full play to the function of the moisture self-supporting to overcome the drought environment and be able to survive. Ther results showed that the new-proposed vegetation restoration technology was feasible.
