观念与空间关联性的消解与重构——拉萨地区乡村藏式民居的变迁研究

Breakage and Reconstruction of Interaction between Notions and Spaces——Study on Transition of Rural Housing in Lhasa Area

藏区正处于转型期,生活形态和建造技术的转变使得传统文化观念与物质空间的关联性被削弱。研究将拉萨地区20世纪80年代之后建造的民居分为3个阶段,从自然观、天梯说、洁净观、中心说和防卫观的角度阐释文化观念与空间组织两者关系的演变趋势及其动因。以此为基础,以当下藏区乡村的建造逻辑为制约条件,明确重构文化观念与空间关联性的原则、措施和策略,并以楼梯为分型要素提出可行的空间组织方式。

Tibetan areas are in a transitional period with changing in lifestyle and construction techniques,which have weakened the relevance between traditional cultural concepts and material space.The research divides the residential buildings that built after the 1980 s in Lhasa into three stages,and explains the evolutionary trends and motivations of the relationship between cultural concepts and spatial organization from the perspectives of nature,ladders,cleanliness,centralism,and defense.Based on this,with the current rural construction logic in Tibetan areas as the constraints,the principles,measures and strategies for restructuring cultural concepts and spatial relevance are clearly defined,and feasible spatial organization methods are proposed using stairs as the subtype element.
