| 摘 要： | 本文应用土壤水能量的概念——土水势,分析了奈曼沙地几种固沙植被,结果表明在干旱的8～10月在年降水量仅366毫米的奈曼沙区,在无地下水和灌溉补给的情况下,樟子松、小叶杨、小叶锦鸡儿、木岩黄芪人工植被不断恶化其自身的立地水分状况,很难长期维持其稳定性。而差把嘎蒿并未严重恶化自身的立地水分状况,群落的演替受立地水分状况的影响不大。

| Abstract: | Using the conception of water energy of soil-soil water potential, the paper analysed some sand-fixation vegetations in Naiman sand area. The results shown as follows:In arid period August to October, the site moisture status of P. sylvestris var. mongolia, P. simonii,C- microphylla and H, frutic.QSum var. ligunosum were deteriorated by themselves. This caused these vegetations hardly keep steady, but the site moisture status of A. halodendron was not worsened by itself seriously. |
