In the light of the characteristics of cold plateau,we study the planting composition of tree species and the choice of tree and herbages species,as well as the techniques of site preparation,fighting-drought forestation coverage,and new fighting-drought materials in the low forest region of Datong County,Qinghai Province.As a result of the study,the integrated forestation technology suitable for the cold plateau and the low mountains of the loess hilly region is suggested.The technology can provide a technical base for the Project of Converting Slope Farmland into Forestland in both the region and other similar regions.
