摘要:

以城市历史景观视角对拉萨、江孜、日喀则等卫藏典型历史城镇进行研究，通过建立案例城镇格局形态、簇群肌理、地标风貌同卫藏地区①高原物候环境、政教统治传统、佛教文化信仰的价值关联，识别其历史景观的地域特征；通过梳理吐蕃王统、分裂割据、萨迦帕竹政权、甘丹颇章政权以及现代化发展期5个阶段卫藏城市景观的特征演变，解译其层积规律，剖析当前文脉断层的成因机理，提出该地区未来历史环境保护更新的对策与方向。

Abstract:

Based on the methodologies of Historical Urban Landscape (HUL), the paper systematically analyzed the historic landscape of the typical cities in ü-Tsang. By setting up the value cohesion between the landscape carriers and their shaping factors, the authors distinguished their regional characteristics. By comparing and associating the landscapes in different periods simultaneously, the paper interpreted the landscape's historic layering disciplines. Finally, the paper further analyzed the reason of urban landscape breaks during the rapid urbanization epoch in Tibet, then put forward the countermeasures and directions for their future protection and regeneration.
