摘要

本研究采用基于人工智能的方法，利用非负矩阵分解工具（一种主题建模方法）来识别水文学的重点研究领域。通过严格的效度分析，将观测到的热点话题分为“流域”和“土壤湿度”两大主题链。它以2022年1月1日至2023年12月31日的研究为重点，考察了“流域”和“土壤湿度”这两个相互关联的主题，经过专家评审，缩小到130个。为了清晰和全面的理解，这些研究项目已严格地以表格形式详细说明。主要研究结果表明，67%的研究集中在“流域”，47%的研究集中在“土壤湿度”，14%的研究集中在两者上，“气候变化”是这些主题的主要焦点。该综述强调，在数字化的推动下，软件、人工智能和机器学习在水文学领域的应用越来越多。优化和预测被确定为突出的研究领域，反映了气候危机和水资源管理在当代研究中的持续相关性。

An NMF-based qualified review of the trending topics in hydrology in the current era

This study employs an AI-based approach using a non-negative matrix factorization tool, a kind of topic modeling method, to identify key research areas in hydrology. The observed hot topics were categorized into two main topic strands through a rigorous validity analysis which are “river basin” and “soil moisture.” Focusing on studies from January 1, 2022, to December 31, 2023, it examines the interconnected topics of "river basin" and "soil moisture," narrowed down to 130 by expert review. These research items have been rigorously detailed in a tabular form for clarity and comprehensive understanding. Key findings indicate that 67 % of studies focus on “river basin,” 47 % on “soil moisture,” and 14 % on both, with “climate change” being a primary focus across these topics. The review highlights the increasing use of software, AI, and machine learning in hydrology, driven by digitalization. Optimization and forecasting are identified as prominent research areas, reflecting the ongoing relevance of climate crisis and water resource management in contemporary research.

期刊介绍： Physics and Chemistry of the Earth is an international interdisciplinary journal for the rapid publication of collections of refereed communications in separate thematic issues, either stemming from scientific meetings, or, especially compiled for the occasion. There is no restriction on the length of articles published in the journal. Physics and Chemistry of the Earth incorporates the separate Parts A, B and C which existed until the end of 2001. Please note: the Editors are unable to consider submissions that are not invited or linked to a thematic issue. Please do not submit unsolicited papers. The journal covers the following subject areas: -Solid Earth and Geodesy: (geology, geochemistry, tectonophysics, seismology, volcanology, palaeomagnetism and rock magnetism, electromagnetism and potential fields, marine and environmental geosciences as well as geodesy). -Hydrology, Oceans and Atmosphere: (hydrology and water resources research, engineering and management, oceanography and oceanic chemistry, shelf, sea, lake and river sciences, meteorology and atmospheric sciences incl. chemistry as well as climatology and glaciology). -Solar-Terrestrial and Planetary Science: (solar, heliospheric and solar-planetary sciences, geology, geophysics and atmospheric sciences of planets, satellites and small bodies as well as cosmochemistry and exobiology).
