摘要:

凝结水作为由气-界面相变形成的隐匿性水源,在干旱生态系统中具有不可替代的水文补偿效应。本文基于中国生态系统研究网络临泽站的长期定位观测,系统梳理了临泽荒漠区凝结水形成机制及其生态水文效应,重点围绕以下两方面展开:(1)沙质生境和砾质生境土壤凝结水的形成机制与水量贡献,解析其发生规律及关键影响因素。(2)凝结水对荒漠植物生长的作用机制,包括对植物种子萌发调控效应及其在叶片水分利用与光合产物积累中的功能。未来应着力构建长期立体化监测网络,深化凝结水在生态系统碳-水-养分循环中的综合作用研究,并揭示气候变化背景下凝结水与生态系统的耦合响应关系,从而为干旱区生态恢复和水资源可持续管理提供科学依据。

Abstract:

Dew, an often-overlooked water source formed through phase change at the air‑interface, plays an irreplaceable role in compensating for water scarcity in arid ecosystems. Based on long‑term field monitoring at the Linze Inland River Basin Research Station of the Chinese Ecosystem Research Network, this paper systematically reviews the formation mechanisms and ecohydrological effects of dew in the Linze desert area, focusing on two main aspects: (1) the formation mechanisms and water contribution of soil moisture condensation in sandy and gravel desert habitats, analyzing its occurrence patterns and key influencing factors; and (2) the mechanisms by which dew affects desert plant growth, including its regulatory effects on seed germination and its function in leaf water use and photosynthetic product accumulation. Future efforts should focus on establishing a long-term, multi-dimensional monitoring network, deepening research on the integrated role of dew in ecosystem carbon‑water‑nutrient cycling, and elucidating the coupled responses between dew and ecosystems under climate change, thereby providing a scientific basis for ecological restoration and sustainable water resource management in arid regions.

Key words: desert habitat, dew, desert plants, plant-water relations, ecohydrological effects
