Dams can effectively regulate the spatial and temporal distribution of water resources, where the rationality of dam siting determines whether the role of dams can be effectively performed. This paper reviews the research literature on dam siting in the past 20 years, discusses the methods used for dam siting, focuses on the factors influencing dam siting, and assesses the impact of different dam functions on siting factors. The results show the following: (1) Existing siting methods can be categorized into three types—namely, GIS/RS-based siting, MCDM- and MCDM-GIS-based siting, and machine learning-based siting. GIS/RS emphasizes the ability to capture and analyze data, MCDM has the advantage of weighing the importance of the relationship between multiple factors, and machine learning methods have a strong ability to learn and process complex data. (2) Site selection factors vary greatly, depending on the function of the dam. For dams with irrigation and water supply as the main purpose, the site selection is more focused on the evaluation of water quality. For dams with power generation as the main purpose, the hydrological factors characterizing the power generation potential are the most important. For dams with flood control as the main purpose, the topography and geological conditions are more important. (3) The integration of different siting methods and the siting of new functional dams in the existing research is not sufficient. Future research should focus on the integration of different methods and disciplines, in order to explore the siting of new types of dams.

大坝选址:回顾

大坝可以有效调节水资源的时空分布,大坝选址的合理性决定了大坝的作用能否有效发挥。本文回顾了近20年来关于大坝选址的研究文献,讨论了大坝选址的方法,重点研究了影响大坝选址的因素,评估了不同大坝功能对选址因素的影响。结果表明:(1)现有的选址方法可以分为三类,即基于GIS/RS的选址、基于MCDM和MCDM-GIS的选址以及基于机器学习的选址。GIS/RS强调捕捉和分析数据的能力,MCDM具有权衡多个因素之间关系重要性的优势,机器学习方法具有很强的学习和处理复杂数据的能力。(2) 选址因素因大坝的功能而异。对于以灌溉和供水为主要目的的大坝,选址更侧重于水质评价。对于以发电为主的大坝,表征发电潜力的水文因素最为重要。对于以防洪为主要目的的大坝,地形和地质条件更为重要。(3) 现有研究中不同选址方法的整合和新功能大坝的选址不够充分。未来的研究应侧重于不同方法和学科的整合,以探索新型大坝的选址。(2) 选址因素因大坝的功能而异。对于以灌溉和供水为主要目的的大坝,选址更侧重于水质评价。对于以发电为主的大坝,表征发电潜力的水文因素最为重要。对于以防洪为主要目的的大坝,地形和地质条件更为重要。(3) 现有研究中不同选址方法的整合和新功能大坝的选址不够充分。未来的研究应侧重于不同方法和学科的整合,以探索新型大坝的选址。(2) 选址因素因大坝的功能而异。对于以灌溉和供水为主要目的的大坝,选址更侧重于水质评价。对于以发电为主的大坝,表征发电潜力的水文因素最为重要。对于以防洪为主要目的的大坝,地形和地质条件更为重要。(3) 现有研究中不同选址方法的整合和新功能大坝的选址不够充分。未来的研究应侧重于不同方法和学科的整合,以探索新型大坝的选址。选址更侧重于水质评价。对于以发电为主的大坝,表征发电潜力的水文因素最为重要。对于以防洪为主要目的的大坝,地形和地质条件更为重要。(3) 现有研究中不同选址方法的整合和新功能大坝的选址不够充分。未来的研究应侧重于不同方法和学科的整合,以探索新型大坝的选址。选址更侧重于水质评价。对于以发电为主的大坝,表征发电潜力的水文因素最为重要。对于以防洪为主要目的的大坝,地形和地质条件更为重要。(3) 现有研究中不同选址方法的整合和新功能大坝的选址不够充分。未来的研究应侧重于不同方法和学科的整合,以探索新型大坝的选址。地形和地质条件更为重要。(3) 现有研究中不同选址方法的整合和新功能大坝的选址不够充分。未来的研究应侧重于不同方法和学科的整合,以探索新型大坝的选址。地形和地质条件更为重要。(3) 现有研究中不同选址方法的整合和新功能大坝的选址不够充分。未来的研究应侧重于不同方法和学科的整合,以探索新型大坝的选址。
