The human-water relationship is one of the most important interactions between humanity and nature, and studying its measurement methods is of great significance for understanding human-water systems. These methods not only provide scientific tools for revealing the interactions between human society and water systems, but also offer technical support for water resources management, ecological protection, and sustainable socio-economic development. Based on a review of previous research, this paper systematically summarizes the measurement methods for human-water relationships, categorizing them into six major types: comprehensive evaluation, correlation analysis, quantitative calculation, model simulation, optimization and regulation, as well as coupling measurement. A detailed analysis of the characteristics and application areas of each method is provided. Furthermore, this paper explores the coupling relationships between these methods, revealing their complementarity and synergy in the study of human-water systems, and discusses the future development directions of these measurement methods. These six methods can be used independently or in combination for practical applications, providing a methodological framework for the study of multi-scale, multi-factor human-water systems. The paper emphasizes the intelligent transformation of measurement methods and the interdisciplinary and multi-method integration, providing technical support and theoretical foundation for in-depth research in the field of human-water relationship studies.
