摘要

[目的]探究梭梭水力提升与浅根系植物优势度、丰富度和多度之间的关系，以了解干旱区荒漠林内深、浅根系植物的种间关系，对干旱荒漠区植物的利用与保护提供理论依据。[方法]利用群落调查、同位素示踪和对比分析等方法对新疆艾比湖荒漠中梭梭是否拥有水力提升、以及其与植物优势度、多样性之间的关系进行了探索。[结果]①梭梭拥有水力提升现象； ②相对梭梭树冠外的浅根系草本和灌木，其树冠下浅根系草本和灌木的生长优势度指数较高，长势更好； ③一年生长过程中，梭梭树冠下灌木和草本群落的物种多度和丰富度均显著高于树冠外（p < 0.05）。[结论]干旱区荒漠群落的建群种梭梭拥有水力提升过程，该过程能够改善浅层土壤水分条件，从而使得其伴生的浅根系草本和灌木的长势更好，影响着干旱区荒漠群落的物种多样性维持过程。

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.
