中文摘要	通过在乌兰布和沙漠吉兰太试验区进行的造林田间试验,以根系沙层含水量,风蚀沙埋状况作为影响造林成活和保存的分析因子,得知,(1)乔木状沙拐枣裸沙造林的适宜根系沙层含水量应大于3%造林时可使成活率提高到90%以上.(2)当沙层含水量为2.5～3%时,在控制风蚀,加大造林密度的前提下,也可达造林目的.(3)吉兰太试验区自然沙体含水量多数在2.5%以下,少数可达2.5%～3%,所以此区种植乔木状沙拐枣治理流沙,应进行灌溉,冬春灌水皆可.(4)风蚀明显降低乔木状沙拐枣的造林成活率,但灌水可以在一定程度上达到抑制风蚀危害的作用;沙埋对造林成活率没有影响.(5)从造林成活率和翌年保存率看,乔木状沙拐枣抗风蚀沙埋的能力远较梭梭和花棒为高.试验表明,乔木状沙拐枣是吉兰太试验区比较适宜的固沙先锋灌木树种.
英文摘要	The field experiment made in Wulanhuh Desert Jilantai areas through investigating factors of affor-estation influenced by water content level ,erosion and deposition of sands shows: (l)the rates of plants survival can be raised over 90% in condition that water content is more than 3% in the land layer ex-ploited by plant roots; (2): Afforestationed can be achieved in the condition of 2. 5~3% of WCL and control of wind erosion and increase the density of afforestation; (3) Majority of water contents in this area are lower than 2. 5% and minority can he reached to 2. 5~3% so Calligonum arborescent must he irrigated in order to manage moving sands either in winter or in spring; (4) wind erosion can appreciably reduce the survival rate of Calligonum arborescuns i Yet irrigation can somewhat prohibit the damages of wind erosion. Deposition of sand has no significant impact on survival rate of afforestation; (5) Form survival rate of afforestation and remain rate we can see that the power of plant resistance to erosion and deposition of sands is far more stronger than HalnxyJon ammodendron (C. a. mey. )Bge and Hedysarum scoparium Fish. Et. Mey . It is concluded that Calligonum arborecan. L. is a appropriate plant to control sand.
