摘要
生态水文过程是生态水文学的重要研究内容,是生态系统中水文过程和生态过程通量变化间的互馈关系。油蒿(Artemisia ordosica)作为我国特有的优良固沙物种,在荒漠生态系统重建与恢复中起着非常重要的作用。本文以生态水文学为指导思想,综述研究了降水、冠层降雨再分配、根系水分再分配、土壤水分变化、蒸散发以及油蒿群落演替等生态、水文过程中油蒿与水文环境间的相互作用关系,提出现存的问题和未来研究应关注的方向,为后续研究提供理论依据。
Eco - hydrological process is always an important part of the study of eco - hydrology, and it is feedback relationship in flux changes between hydrological process and ecological process in the ecosystem. Artemisia ordosica plays a very important role in recov- ery and reconstruction of desert ecosystem as a special fine species of fixation sand in China. Taking eco - hydrology as thinking guid- ance, the aim of this paper is focused on reviewing the interaction relationship between artemisia ordosica and hydrological environment in the ecological and hydrological process from precipitation, canopy rainfall redistribution, root hydraulic redistribution, soil water changes, evapotranspiration and artemisia ordosica community succession. Furthermore, the existing problems and the directions to be concerned in future were proposed, Which will provide the theoretical basis for the follow- up studies.
