摘要:

凝结水是当物体表面温度下降至露点温度后,大气中的气态水在物体表面形成的水源。在水资源有限的干旱区,凝结水是生态系统中重要的水分补给来源。本文系统梳理了凝结水的形成条件和观测方法,探讨了经验模型、物理模型、半经验模型及人工智能算法的适用性与局限性,分析了凝结水量的时间变化规律和空间分布特征及其对气候变化的响应机制,并指出当前时空模拟精度主要受到数据精度、参数简化及下垫面复杂非均质性的限制。在此基础上,提出未来应深化自然下垫面对凝结水的影响机制分析,以提升模型在复杂环境中的适用性,融合多源数据,驱动人工智能算法结合物理模型来模拟凝结水的时空分布规律,并强化在气候变化背景下凝结水生态效应的研究。

Abstract:

Dew is a source of water formed on the surface of an object by gaseous water in the atmosphere when the surface temperature of the object drops to the dew point temperature. In arid regions with limited water resources, dew serves as a crucial water supply source in ecosystems. This paper systematically reviews the formation conditions and observation methods of dew, discusses the applicability and limitations of empirical models, physical models, semi-empirical models, and artificial intelligence algorithms, analyzes the temporal variation patterns and spatial distribution characteristics of dew volume along with its response mechanisms to climate change, and points out that current spatiotemporal simulation accuracy is primarily constrained by data precision, parameter simplification, and the complex heterogeneity of underlying surfaces. Building on these findings, future research should deepen the analysis of the influence mechanisms of natural underlying surfaces on dew to enhance model adaptability in complex environments, integrate multi-source data to drive artificial intelligence algorithms combined with physical models for simulating the spatiotemporal distribution patterns of dew, and strengthen studies on the ecological effects of dew under climate change scenarios.

Key words: arid regions, dew, artificial intelligence, spatial and temporal simulation
