| 摘 要： | 在古尔班通古特沙漠引水渠沿线建植5a的人工固沙区内,选择自然生长的沙蒿和沙拐枣灌丛,依据冠幅大小设置5个水平距离梯度和4个土层深度梯度.对比研究了二者的土壤水分特征.结果表明,随土层深度的增加,两种灌丛土壤含水量均呈增加趋.,中下部2层(20～40 cm和40～60 cm)土壤含水量显著(P<0.05)高于上部2层(0... |

| Abstract: | The natural Artemisia arenaria and Calligonum mongolicunl shrubs were selected in five-year sand fixation area beside the desert canal in Gurbantunggut Desert,Northwest China.According to shrub crown size,five horizontal distance levels and four vertical depth levels were chosen to contrastively study the soil water content(SWC) of the two shrubs.The result showed that the SWC values increased with the soil layer depth,the AWC values of two lower layers(20~40 cm,40~60 cm) were significantly(P<0.05) more tha... |
