| Abstract: | On the basis of environmental characteristics and vegetation distribution in the loess hilly-gully region of northern Shaanxi Province, there have 5 areas for vegetation econstruction been demarcated. These are the gully region along Maowusu desert, the region of loess hills and Yellow River valley, the region of Baiyushan and Hengshan mountains in the northwest, the region of loess hills and Yellow River valley in the east and the region of secondary forest along Huanglong and Laoshan mountains in the south. Regionally suitable vegetation species, directions of development, reconstruction tasks, reconstruction methods for every region and trees and grasses suitability for planting or sowing are considered. |
