摘要
以塔里木河上游为研究区，研究不同植被覆盖对土壤水盐空间分布规律的影响，结果表明：甘草群落0-150cm的平均含盐量高于其他群落，各植被群落0-20cm土层的盐分含量基本高于20cm以下土层的盐分含量，并且各植被群落在不同土壤深度下的盐分变化规律与土壤含水量的变化规律基本一致。胡杨一铃铛刺群落随着植被盖度的增加，其土壤各层的水分含量均增加；除表层（0-5cm）外，土壤其他各层盐分含量均随盖度的增加而减少。除表层（0-5cm）外，多枝柽柳群落下的土壤其他各层的土壤含水量均随盖度的增加而增加；而土壤各层的盐分含量随盖度的增加而减少。
The research on the plant covering impact on the spatial distribution of the soil moisture and salt was carried out in the upper reaches of Tarim River. The results showed that soil salt of Glycyrhiza inflata Bat was more higher than the others community in the 0-150cm＇s depth. Soil salt of 0-20cm＇s depth was more higher than soil salt of 20-150 cm＇s depth. Spatial distribution of the soil salt and moisture was unanimously in different depths of every community. In Populus euphratica Oliv-Halimodendrum lolideneon,the soil moisture of the different depth was increased with the vegetation community covering ; except of 0-5cm＇s soil depth,the soil salt of the other depths was decreased with the vegetation community covering. In Tamaricaceae ramosossoma Ledeb,except of 0-5cm＇s soil depth,the soil moisture of the other depths was increased with the vegetation community covering;the soil salt of the different depths was decreased with the vegeta- tion community covering.
