| 摘 要： | 克隆生长赋予沙棘生理整合和觅养行为等特性,使其不仅能够适应干旱缺水的环境,并且具有较高的繁殖及生存有效性,通过林缘扩散和林窗更新维持群落持久性及稳定性。同时,沙棘能通过克隆生长产生大量彼此联结的分株,形成庞大的地下网络结构,从而有效地保持水土、防风固沙、稳固土壤基质,并为其他植物的定居创造有利条件。

| Abstract: | Hippophae adapts to the drought environment and has a high capability in propagation and survival rate with physiological integration and foraging behavior as a result of clonal growth.And so the species can maintain or recover its population endurability and stability by gap regeneration and edge dispersal with clonal growth.The species also possesses an effective function in soil and water conservation,wind break and sand fixation,substratum firming with a large amount of connected ramets through spacer and underground root net-system,and thus transforms the site condition for the establishment of other plant communities. |
