| 摘 要： | 通过对比法研究了沙地土壤种杨树刺槐混交林后持水特性的变化。结果表明，沙地土壤种植杨树，刺槐纯林和混交林后，土壤持水特性，孔隙分布状况和水容量得到了改善和提高，提高和改善的幅度均以混交林最大，无林地植被覆盖后土壤持水性能改善的根本原因在于土壤有机质含量的增加，从而改善了土壤的孔隙状况。

| Abstract: | The change of soil moisture retention after planting mixed forest of Populus spp.and Robinia pseudoacacia was studied by comparative method. The results showed that soil moisture retention, spatial distribution of soil pore, and soil water capacity were improved and increased in sandy soil after Populus spp. and Robinia pseudoacacia being planted, and the improvement in the mixed forest of Populus spp. and R.pseudoacacia was greater than that in the pure forest of Populus spp.or R.pseudoacacia .The basic reason of soil moisture retention being improved was the increment of soil organic matter,which improved soil pore condition. |
