中文摘要	以古尔班通古特沙漠免灌溉人工林为研究对象,对选取的样地进行不同强度的平茬与间伐处理,观测地表100 cm 内土壤的含水量。结果表明: 抚育后人工林对土壤水分的利用规律发生了明显的变化,梭梭林经过间伐后各土层含水量的下降减小了,且间伐强度越大这种趋势越明显,甚至在梭梭的生长季内50 ~ 70 cm 层和70 ~ 100 cm 层间伐样地土壤含水量升高了。此外,间伐处理使不同月份土壤含水量的变异趋于平稳; 沙拐枣林经过平茬后各土层含水量的下降增大了,且平茬处理使不同月份间土壤含水量的变异增大了。因此,对古尔班通古特沙漠无灌溉人工梭梭林进行间伐抚育,有助于对沙漠土壤100 cm 土层内水分的保蓄,而对沙拐枣林进行平茬促进了沙拐枣对沙漠土壤100 cm 土层内水分的吸收。
英文摘要	Taking the non-irrigated plantations Gurbantunggut Desert as study subjects,soil water contents within 100 cm below the ground were investigated under different management (cutting,thinning)from April to September 2012. The results showed that cutting and thinning treatments changed the soil moisture utilization ways of the plantation. The soil moisture in each layer was decreased after the thinning of Haloxylon persicum forest. However, the decrease of the soil moisture in the soil layers decreased with the increase of the soil depth. The soil moisture even raised in 50-70 cm and 70-100 cm depths. The stronger the thinning,the shallower and higher the soil moisture. The thinning can also keep the monthly soil moisture stable. The soil moisture decreased at each soil layers as well after the cutting of the artificial Calligonum rubicundum forest. The cutting also increased the variation of the soil moisture in different months. In conclusion,it would be benefits for conserving soil moisture within 100 cm below the ground through thinning the artificial H. persicum forest; and cutting the artificial C. rubicundum forest to improve the effectiveness of the root water absorption.
