桑基图的可视化图式在建成环境领域的应用

摘要

As a kind of visualization graphic which could analyze and present the resources flow,Sankey diagram can quantify the operation mechanism and clarify the transformation of elements in system.As a result,it has been applied in the field of energy flow,resources recycling,materials metabolism as well as infrastructure configuration.This paper summarizes the development process and application in relevant fields of Sankey diagram and illustrates its organization features,elements categories and presentation characteristics in the built environment from the quantitative and qualitative perspective,and clarifies its significance and contribution in terms of system optimization,processing analysis,result evaluation as well as thinking configuration etc.Meanwhile,the paper elaborates the application and presentation mechanism of Sankey diagram,and looks forward to its development tendency.%桑基图作为一种对资源流动进行分析和表达的可视化图式,因具有对系统要素的运行机制量化表现的特性,可以更好的阐释各类资源要素在空间中的转换和传递等运行状况,故在能源流动、资源循环、物质代谢、基础设施配置等方面有着广泛应用.文章概述了桑基图的发展过程及在相关应用领域的应用,从定性和定量上对其组织结构特点、组成要素类型和表达表现特征进行归纳总结,阐明了桑基图在建成环境领域内,对于系统结构优化、过程分析、成果评价验证及设计思维构建等方面的意义和优势;同时,结合典型的桑基图应用案例,从建筑、社区和区域等不同尺度层面,阐述了其应用特点和表达机制,并对桑基图的发展趋势进行了展望.
