| 摘 要： | 针对砒砂岩地区困难立地生态恢复与合理利用问题,选取2～10a的沙棘人工林为研究对象,对不同林龄群落结构及植物多样性进行比较研究.结果表明:砒砂岩地区人工种植沙棘后,随着沙棘林龄的增长,植物种类逐步增加.在造林初期,林下草本植物以一年生且旱生的植物地蔷薇为优势种群;造林3a后,以多年生植物赖草、阿尔泰狗娃花为主要优势种;...

| Abstract: | Aiming at ecological restoration and reasonable utilization of Soft Rock Region,taking 2～10 years Hippophae rhamniodes foves as research object.Community structure and plant diversity were studied,the results showed species diversity in artificial Hippophae rhamniodes community of diffierent age was more and more plentiful as the Hippophae rhamniodes community age increase.In the preliminary stage,Chamaerhodos erecta was dominant population in the community,it is annual and xerophytic plants;3 years later,Leymus secalinus and Heteropappus altaicus are dominant species,they are perennial plant;8 years later,Stipa bungeana and Thymus serpyllum var.mongolicus become constructive species,they are zonal vegetation.The propotion of annual plants reduced,the community structure tends to steady and the hierarchical structure is more reasonable. |
