Relationships Between Hydraulic Lift of Haloxylon Ammodendron with Growth Condition, Abundance and Richness of Shallow-rooted Plants
摘要
Abstract
[Objective] Studying the relationship between hydraulic lifting(HL) of Haloxylon and the dominance,richness and abundance of it neighborhood shallow rooted plants.To provide theoretical basis for understanding the interspecific relationships,the utilization and protection of plants in arid desert area.[Methods] Isotope tracing,community investigation and comparison analysis were employed to validate the HL of Haloxylon ammodendron,and to explore its influences on community species abundance and richness in arid desert region.[Results] ①Haloxylon.ammodendron had HL phenomenon;②Those shrubs and herbs that grew under the Haloxylon ammodendron canopy(under community:UC) showed better growth status than the ones growing outside(outside community:OC);③There were significantly higher species richness and abundance in UC than in OC(p＜0.05) along the plant growing season.[Conclusion] Haloxylon ammodendron HL significantly ameliorates the water conditions of the shallow soil,which then influences the growth condition of shrubs and herbs,and the diversity assembly in arid desert communities.关键词
