A STUDY ON DESCRIPTION OF "PLAN CONFIGURATION" AND EVALUATION OF "LEGIBILITY"

(1)流通网络句法分析的有效性和局限性：应用空间句法理论和图论对步行线路的流通网络进行分析，对于大型流通网络的量化和比较具有一定的有效性。作为案例研究，通过对规划小城镇街道网络与历史古镇街道网络的对比分析，发现两者存在较大差异：前者的网络是紧密的/高度集成的，主要街道通常位于外围区域，与其他街道隔离，而后者的主要街道则在它们所在的地方集成。然而，这种句法分析，这只是基于这样一种假设，即任何生活空间都可以被概念化为抽象空间，从中消除了诸如功能、宽度、纹理、家具等实际特征。空间的这些方面如何影响空间的“易读性”有待于进一步研究。(2)“易读性”的含义和方法论问题：本研究中的“易读性”概念依赖于相对传统的认知科学中的“表征理论”。而认知理论的新发展趋势则提出了“情境学习理论”，认为任何学习都可以在特定的情境中结合特定的活动来实现。从这个角度出发，我们必须发展新的有效的空间“易读性”概念和理论。环境模拟研究的方法论不可避免地存在一定程度的脱离现实的现象，也应该从环境的生态有效性角度进行反思。

(1) The validity and limit of the syntactic analysis of circulation network :The analysis of circulation network of pedestrian routes by the applications of space-syntax theory and theory of graphs could show some extent of its validity for the quantification and comparison of large circulation networks. As a case study, the comparative analysis between the street networks of planned towns and those of historical old towns resulted in big differences as follows ; in the former the networks were compact/highly integrated and main streets generally located in the periphery zone were segregated from the other, on the other hand, in the later main streets were integrated whereever they were located.This kind of syntax analysis, however, only stands on the assumption that any living space could be conceptualized as an abstract space from which the actual features such as functions, width, texture, furniture, etc. are eliminated. It was remained in future study how these aspects of space could effect "legibility" of the space.(2) The meaning of "legibility" and the issues of methodology :The concept of "legibility" in this study depended on so to speak "representation theory" in relatively traditional cognitive science. But the new trend of cognitive theory claims the "situated learning theory" in which any learning could be realized in connection with particular activity in particular situation. From this point of view, we have to develop new valid concept and theory of "legibility" of space. The methodology in environmental simulation study, which is inevitably in some extent abstracted from the reality, should be as well reconsidered in terms of the ecological validity of the environments.
