摘　　要：通过对荒漠半荒漠地区沙枣、白蜡、油松等８个造林树种根系生长潜力（ＲＧＣ）的调查，采用恢复率这一相对标准进行分析得出：８个造林树种根系生长潜力的排序，从大到小依次为沙枣、白蜡、早柳、新疆杨、樟子松、油松、侧柏、青海云杉。Based on investigation root system growth latent capacity ofeight afforesting tree species, such as Elaeagnus angustifolia,Fraxinus ch- inensis and Pinus tabulaeformis etc in the desert and semi-desert areas wi-th restoring rate as a relative criterion to conduct analysis. The authorsobtained the decreasing order of root system growth latent capacities of ei-ght species as follows:Elaeagnus angustifolia,Fraxinus chinensis,Salix mat-sudana, Populus bolleana,Pinus sylvestris, Pinus fabulaeformis,Platycladusorientalis and Picea crassifolia.
