| 摘 要： | 在干旱季节研究了沙柳和杨树固沙林土壤含水量的变化,结果表明：随着固沙植被的恢复,土壤水分状况具有恶化的趋势。流动沙丘（对照）0～60 cm土层含水量好于沙柳林地,而在60 cm土层以下深度,土壤含水量有趋同的变化。杨树固沙疏林（郁闭度0.2）0～100 cm土层含水量高于对照（固定沙地）,而郁闭度0.4及其以上的杨树固...

| Abstract: | Through making research on soil water content in fixing sand forest of Salix psammophila and Populus L： in arid season, the results showed ： with the recovery of sand - fixing vegetation, the soil water appeared a trend of deterioration. The soil water content at the layer of 0 -60 cm in moving sandy dune （ck） was better than the one in Salix psammophila forestland, but at the layer under 60 cm, the soil water content had the convergent change. The soil water content at the layer of 0 - 100 cm in sand - fixing open forest of Populus L. （ canopy density at 0.2） was higher than ck （ fixed sandy land）, but the soil water content in sand - fixing forest of Populus L. with canopy density at 0.4 and upper was lower than ck. It reflected that stand density could influence the soil water content directly. |
