摘要
径流系数是表征降雨转化为地表径流比例的重要参数,在水资源管理和城市规划中应用广泛。本文全面评述了径流系数的概念及发展历程、取值方法、影响因素和研究方法,深入探究了不同影响因素下径流系数的变化以及不同研究方法的优缺点,强调了跨学科协作在推动技术创新、整合数据和平衡成本效益方面的重要性,提出了在气候变化和城市化快速推进的当下,其研究所面临的挑战与未来研究方向,指出计算机技术、遥感技术、机器学习等新技术和新方法可以为径流系数的研究提供新视角,为水资源管理和城市规划提供科学的决策支持。
The runoff coefficient is a critical parameter that quantifies the proportion of rainfall converted into surface runoff and is widely used in water resources management and urban planning.This paper provides a comprehensive review of the concept,historical evolution,determination methods,influencing factors,and research methodologies related to the runoff coefficient.It examines how the runoff coefficient varies under different influencing factors and evaluates the advantages and disadvantages of various research approaches.The study emphasizes the importance of interdisciplinary collaboration in advancing technological innovation,integrating data sources,and balancing cost-effectiveness.In the context of rapid climate change and urbanization,it outlines current challenges and future research directions,highlighting how emerging technologies and methods,such as computer technology,remote sensing,and machine learning,can offer new perspectives for runoff coefficient research and provide scientific support for decision-making in water resources management and urban planning.
