Abstract:

Soil moisture is an important indicator for monitoring soil drought, and studying its relationship with climate change helps to reveal the mechanisms of soil drought under the context of global change. Based on the Web of Science Core Dataset, this study analyzes the literature on the topic of the relationship between climate change and soil moisture. The results show that the number of related publications from 1988 to 2023 follows a trend of “stability, growth, sharp increase”. Chinese scholars and research institutions contributed the most publications, but their overall international influence remains lower compared to developed countries such as the United States. In terms of subject areas, research is primarily concentrated in environmental science and ecology, earth sciences, as well as agricultural and forestry sciences. Key research focuses include soil-climate interactions, soil ecosystem management, hydrometeorology and soil drought monitoring, as well as climate data analysis and ecological modeling. In recent years, research hotspots have gradually shifted to the application of cutting-edge technologies, such as multi-source sensing and artificial intelligence, in soil drought monitoring. Furthermore, the impact of extreme climate events on various ecosystems and their corresponding response strategies have become important research directions.

Key words: soil moisture status, climate change, bibliometric analysis, soil drought

摘要：

土壤墒情是重要的土壤干旱监测指标，研究其与气候变化的关系有助于揭示全球变化背景下土壤干旱的发生机制。本文基于Web of Science数据库核心数据集，对气候变化与土壤墒情关系研究主题的文献进行了分析，结果表明，1988—2023年相关文献数量呈“平稳、增长、激增”的变化趋势。其中，中国学者和科研单位发表的文献数量最多，但整体国际影响力相较美国等发达国家仍显不足。在学科分布上，研究成果主要集中于环境科学与生态学、地球科学及农林科学等领域。研究重点包括土壤-气候相互作用、土壤生态系统管理、水文气象与土壤干旱监测，以及气候数据分析与生态模型应用等方面。近年来，研究热点逐渐聚焦于前沿技术（如多源传感监测和人工智能等）在土壤干旱监测中的应用，同时，极端气候事件对不同生态系统的影响及其应对策略也成为重要研究方向。
