中文摘要：
规划支持系统（PSS）是许多相关国际学术会议和文献中日益热门的话题，但在国内规划界却鲜有提及。笔者综述了规划支持系统的产生渊源、定义、内容和实践。规划支持系统的产生与国外城市规划界两个认识上的重要变化有关。一是对计算机在城市规划中作用的看法变化，二是对城市规划本体的认识．从“为公众规划”到“与公众一起规划”的变化．尽管现在对规划支持系统还没有一个统一的定义，其功能、结构、形式也各不相同。但规划支持系统还是具有一些重要的共同特征。规划支持系统都是用于支持多方参与规划的方式，都是提供一个规划师、决策者、普通公众之间交流沟通的平台，规划支持系统本身并不做出决策，也不直接推荐出最佳方案，只是在各个阶段规划的过程中提供支持。所以，规划支持系统不是一种在城市规划中新的计算机技术，而是一种在城市规划中应用计算机技术的新途径，一种运用计算机辅助规划的新方法。最后，对现阶段在中国城市规划实践中，如何应用规划支持系统提出了展望和建议。
英文摘要：
Planning Support System （PSS） is an increasingly popular topic of many international academic conferences and literatures, but it is hardly mentioned in China, First, this paper gives a general review of origins, definitions, contents and practices of PSS. The field of urban planning in western countries is experiencing two fundamental changes that are having a profound impact on the emerging of PSS, One is the change of views for computer-aided planning; the other is the change of planning itself from ＇planning for＇ to ＇planning with＇ the people. Though there are several different definitions for PSS and a great diversity in the capabilities, structures and forms of PSS, all of current PSS have several important common properties. PSS is toolbox to support ＇planning with＇ people and platforms for communication among planners, decision-makers and publics. PSS does not make judgments and decisions, nor does it give recommendations or ‘best＇ plans directly, it only supports planning processes at any particular planning. It can be concluded that PSS is a new approach for a new approach for application of computer-based techniques in urban planning or a new approach for computer-aided planning in brief, rather than a new technology in urban planning. Finally, this paper provides some prospects and suggestions of PSS application in present planning practices in China.
