内容简介

这是一本有关城市高密度与建筑学观念及方法论的文本。

本书以城市高密度为环境条件与预设，论述因高密度而激发的建筑学方法。

内容分为上、下篇两大部分，上篇是背景和基础研究，下篇是经验的总结归纳与方法策略的提取及论述。

第一章从宏观层面论述了高密度建筑学的背景研究——紧缩城市与城市高密度环境。通过大量的数据和理论梳理，从人口、社会、经济、生态环境和城市演进等方面，论述了人类空间诉求的紧迫性和人口膨胀动力、城市化动力、生存条件与环境改善动力、生态补偿动力等因素。阐明人类需要空间的事实，并深入阐述了人类生存与繁衍所需空间与有限空间之间的尖锐矛盾。继而陈述了城市作为人类生存与发展的重要介质是满足空间诉求的切要。以此为依据，再通过中观层面描述城市高密度环境状态；阐述了城市高密度存在的必然性和历史性、对城市多样性与繁荣的价值，以及对可持续发展的积极意义。

第二章分析论述了密度与高密度的含义，并作为基础性内容为后续章节高密度建筑学方法策略的论述提供理论铺垫和技术支持。本章通过基本的数值量度和复合的人类感知概念，以物理密度、感觉密度和高密度三方面解释了密度的多种含义和量度方法。陈述了确定清晰物理密度量度的精确定义和方法，并进一步指出需要将多种密度指标结合成一种整体性的评价方法，用于评价、描述与预测建筑与城市形态、城市环境的关系，以及所呈现的密度状态。最后明确界定了城市高密度的内容和范围，厘清了高密度与城市高密度环境的含义和所指，并寻找发现其中的特征和潜能、存在问题和关联因素，从而为存在于之中的建筑应对策略与方法提供针对性依据。

第三章以时间为线索回顾了自20世纪初到21世纪近百年的基于城市高密度环境条件的建筑应变、实践与发展的历史。解析由城市高密度环境而激发的应对高密度的建筑理想、概念和理念，以及从探索、试验到实践的经验。将近百年的针对城市高密度环境的建筑应变与实践的历史分成三个时间阶段，分别为20世纪初至40年代的初始阶段、50年代至80年代的发展阶段以及90年代至21世纪初的成熟阶段。以密度的视角聚焦、独特地解析其中不同的建筑探索和实践所隐含的策略与应变方法，将从中总结归纳的经验作为第四章高密度建筑学策略的摹本与素材。

第四章在分析、归纳和总结第三章建筑应变与实践的经验基础上，利用第一章背景研究的成果和结论并结合第二章密度的基础技术和理论，展开针对城市高密度环境的建筑学策略的论述，也是高密度建筑学的主要观点。在解释了这种特定环境状态下的建筑学策略的含义和内容之后，提取并归纳高密度建筑学六大策略——多样性原则、亲近性原则、空中空间利用模式、三维立体模式、杂交与共生和空间补偿，并逐一展开深入剖析和论述。

最后本书对所提出的高密度建筑学策略的因果关系和逻辑结构作出总结。作为结论，指出通过高密度建筑学六大策略，以建筑为本，挖掘建筑构成中被密度所激发的潜能和特质，提升建筑空间的质和量并共生于高密度城市环境，最终构建协调发展的城市高密度环境。

This is a discourse of architecture methodology to urban high density.

Taking urban high density surroundings as precondition, the book discusses and elaborates the architecture strategies induced by high density. It is neither the intention for the text to interpret the specific aesthetics of buildings generated from high density nor to be a role taken to state aesthetics. But to search and study the responsiveness and solution of architecture from high density at the viewpoint of architecture while confronting the vital moment of how to develop cities, as well as to find out the architecture strategies to defuse problems produced by urban developing.

The book consists of two sections, the first of which is to study the background and basis of the text while the second section is about the collecting and summarizing of experiences along side with the demonstration for refinement of strategies.

Chapter one discusses the background of the subject on the macro lever, which is about compact city and urban high density surroundings as the precondition of the research subject. It analyzes the urgency of space need appealed by human being, ranging from efficient cause of population explosion, urbanization, improvement aspiration intensely of existence condition and surroundings to ecological compensation, by a large amount of statistics and classification of relevant theories. It not only clarifies the fact of the space need and the contradiction between the limited space and both existence and development of human being as well. Then it demonstrates that cities are the only option to satisfy the space appeal, when taking them as the medium for human being's existence and development. Afterwards it points out that both space appeal and limited space become the justification to support the value of compact city idea. After that, it states the condition of urban high density surroundings by medium perspective, expounds the necessity and historic significance of urban high density, which is the value to urban diversity and prosperousness, and is of the positive significance to the idea of sustainable development.

Chapter two analyzes and expounds the meanings of density and high density in the way from abstract to concreteness by both medium and micro perspectives, which is taken as the basic content of this subject, simultaneously as the technical support and evidence for the following strategies' discussion. It searches and explains the meanings and measure of density according to physical density, perceptive density and high density in the light of both basic numerical measure and the conception of mutual perception. It elaborates the accurate definitions and methods of physical density measurements. Further more it also points out the necessity to evaluate, describe and predict the relation between architecture and both of urban morphology and surroundings, as well as the emerging density status. Finally, this chapter defines the content and scope of urban high density, clarifies the meaning and signified both of high density and its surroundings. Then it searches and finds out the characteristic, potency, contained problems and related elements of urban high density, so that to discover the pertinent evidences for responsive strategies of architecture in urban high density.

Chapter three reviews the history of responsiveness, practice and evolvement of architecture from the beginning of 20 century to present in 21 century upon urban high density surroundings. It analyzes not only the thought, conception and idea of responsive architecture simulated by urban high density surroundings, and the experiences of its searching, experiment and practicing as well, which are taken as the historic content and practical experience of this subject. The history of practice consists of three stages, which are the initial stage from 1900s to 1940s, the developing stage from 1950s to 1980s and the mature stage from 1990s to present in 21 century. It uniquely analyzes the implicated responsiveness and strategies from differentiated researches and practices of architecture focused by view of density. Then it takes the results as the transcription and source for the following chapter that is about the strategies of architecture to urban high density surroundings.

Chapter four elaborates and discusses the architecture strategies to urban high density surroundings based upon the analysis, experiences and results of chapter three, by utilizing the achievements and conclusions of the background study in chapter one along with the basic technologies and theories of density in chapter two. Once interpreting the meaning and essence of the strategies in such specific surroundings, it refines and concludes the six architecture strategies induced from high density, which consists of diversity principle, proximity principle, model of space usage in the air, 3D model, hybrid and coexistence, and space compensation. Each of them is analyzed and discussed deeply one by one.

Ultimately this text gives the conclusions that include the cause and effect of the architecture strategies, and its logic structure as well. As the final conclusion the text declares that the six strategies are of revealing potencies and specialties consisted in architecture stimulated from density, to promote the quantities and qualities of architectural space that coexist coordinately in urban high density surroundings, for the purpose of towards the fine livable urban high density surroundings.

Moreover, this paper summarizes the significance of the strategies to creative ability for architecture, which would be a new research subject for the future.
