沙棘群落生态学研究概述

Summary Research on Community Ecology of Hippophae Rhamnoides

文献综述表明 ,学者们对沙棘的水土保持功能已经给予了充分的肯定 ,但在群落演替规律和数量动态方面的研究结果尚存争议和不足之处 ,这主要是由于忽视了沙棘无性系生长可塑性调节及无性系种群的多层次构件性。因此 ,今后应加强种群扩散规律、生物量分配格局以及水土保持功能与群落结构之间的定量关系研究 ,深化对沙棘生态适应机理的认识 ,为沙棘群落水土保持功能持续发挥提供依据。

The capability of water and soil conservation of Hippophae rhamnoides was highly estimated in published literatures,but there were deficiencies in the research on community succesion and biomass dynamics because of the neglect of clonal growth regulation and its multiple population level.Therefore,studies on the population dispersal,biomass allocation patterns and the quantitative relationship between ability of water and soil conservation and structure of the community should be strengthened so as to understand the ecological strategies of the population,and to provide some foundation for the community sustainable management.
