中文摘要 | 土壤沃岛效应的形成增强了植物对干旱贫瘠环境的适应能力和生态系统的稳定性,在植被重建方面具有重要的生态水文学意义。灌丛树干茎流和根区优先流的水分和养分富集作用对灌丛沙堆土壤沃岛效应的形成、发育和演化具有极其重要的作用。弄清灌丛沙堆演化过程中灌木对土壤水分变化的时空响应和其多样性的维持机制、植被对水分的生态适应对策,是进一步研究灌丛沙堆形成和演替机制的关键。本文综述了灌丛沙堆的形成机理,对灌丛沙堆演化过程中土壤水文过程与植被响应机理以及灌丛树干茎流与根区优先流对土壤沃岛效应的影响进行了阐述,并对灌丛树干茎流与根区优先流研究方法进行了评述。在未来研究中,应加强对灌木地下根系分布及水分和养分沿灌木根系形成的优先通道运移和再分配的研究,以便更好地评价干旱贫瘠环境中树干茎流对灌木群落稳定性和生态系统发育所起的作用。 |
英文摘要 | The enrichment functions of stem flow and root-induced preferential flow of bushwood are of great importance in the formation and growth and evolution of the fertile island of nebkha.It enhances the vegetation adaption to dry and infertile environment and the stability of ecosystem,thereby plays important eco-hydrological roles in plant reconstruction in desert regions.Making clear the temporal and spatial responses of shrubs to the changes of soil water content during the process of the nebkhas evolution,the maintaining mechanism of biodiversity,and the ecological adaption countermeasure of vegetation to soil water is the keys to further study the formation and evolution of nebkha.In this paper,the formation mechanism of nebkha was reviewed,soil hydrologic process and vegetation response during the nebkha evolution process and the influences of stem flow and root-induced preferential flow of shrubs on the soil fertile island were demonstrated,and the study methods of stem flow and root-induced preferential flow of shrubs were summarized as well.For better evaluating the function of stem flow to the stability of shrub communities and the development of ecosystems in desert regions,more attentions should be paid on the root distribution of shrubs and the movement and redistribution of water and nutrition along with preferential flow path caused by shrub roots in the future research. |
