摘 要：
采用时空替代法,对科尔沁沙地黄柳(Salix gordejevii)+杨柴(Hedysarum leave)植物再生沙障人工群落的结构特征进行研究。结果表明:1)利用植物再生沙障治理流动沙丘可以形成具有多物种、多层片、多层次垂直结构的沙障群落,其水平结构呈网格状沙障结构与障间小群落在空间上镶嵌互补,均衡分布的格局,具有很好的防风固沙和植被恢复效果;2)再生沙障建植后第5年开始,沙障群落进入了衰退时期,适时采取科学的经营管理措施对于维持沙障群落的稳定,保障其效益的长期发挥是非常重要的。

摘 要：
This paper presents the structure of artificial communities of plant regenerative sand-barrier in Horqin Sandy Land.The results show that: comparing the contrast community(formed by enclosure management for restoring vegetation naturaly on sand-dune for 7 years),some positive aspects of the artificial communities were showed as follows: 1) The level of the species diversity was more higher;2)the vertical structure was so complicated that the surface of sand-dune was covered by multiple layers of plants;3) there were higher coverage rate and biomass;4) from 5th year,the artificial community was beganning to decay and it was very important to improve the stability of artificial communities by suitable means of management.
