1997年开始研究塔克拉玛干沙漠腹地沙土在不同灌溉方式和含盐地下水利用管理下土壤水分和盐分的分布及动态变化。结果表明：在塔克拉玛干沙漠腹地沿荒漠公路建设生物流沙治理体系的过程中，利用含盐地下水可对幼苗进行滴灌（对平地可进行沟灌）；流沙治理林带宜在植树造林的同一年灌溉频次为20 d，灌溉量为30 kg/m2·次。随着林龄的增加，可适当提高灌水定额，延长灌水间隔。
The study on the distribution and dynamic changes of soil moistures and salts under different irrigating methods and managements of using saline groundwater on the sand lands of the hinterland of the Taklimakan Desert, started in 1997. The results show that drip irrigation can be applied to seedlings (furrow irrigation can be applied to level lands) using saline groundwater in the process of constructing the biological shifting sand control system along the desert highway in the hinterland of the Taklimakan Desert; an irrigation frequency of 20 days and an irrigation amount of 30 kg/m2·time are suitable to the shifting sand control forest belts at the same year as they were afforested. Along with the increase of forest age, the irrigation norm can be properly increased, the irrigation interval can be prolonged.
