近年来，伴随新农村建设的蓬勃发展，大量传统村落被大规模拆除、废弃，村落更新重走城市更新大规模改造的老路。其中，藏族村落地处偏远，防灾扶贫等因素导致大量大规模改造活动，村落空间被大肆拆改，传统文脉亟待保护。本文对川西北藏族村落改造规划设计进行研究，研究内容及结论如下：（1）回顾城乡更新改造理论及实践。城市更新改造普遍呈现由大规模改造转向小规模渐进式更新的趋势，更加注重更新改造的整体性及公众参与性。然而，乡村更新重走城市更新大规模改造的老路，藏族村落地处三区三州深度贫困区域，大规模改造频发，藏族村落及文化亟待保护。（2）探究川西北藏族村落及民居传统形态特征，明确保护重点。以30套实地调研测绘资料为基础，探究村落选址及布局，民居整体空间形态、内部空间结构、建筑营建技术、建筑空间造型及建筑装饰艺术的传统形态特征。（3）梳理川西北藏族村落更新改造面临的问题，明确改造难点。藏族传统村落普遍存在基础设施落后、传统风貌衰败、公共空间匮乏、民居居住品质低等问题。已有的改造以规模和位置为分类依据，分为异地搬迁式、就近搬迁式、原址重建式、临近扩建式、原址改造式，分别引发了不同程度的旧村空间废弃、风貌衰败，新村同质化建造等问题。（4）综合保护重点及改造难点，提出川西北藏族村落更新改造的策略。针对普遍问题及改造引发的问题，结合小规模渐进式更新理论，提出村落改造规划及民居改造设计方法，分别包含明确改造规范、建立评估机制、健全基础设施、修缮传统风貌、营造公共空间，评估现状建筑、调整功能布局、提升物理环境、优化结构体系、美化外部环境。（5）基于村落更新改造策略，开展理县木堆藏寨改造规划设计。开展村落整体规划；将公共晒坝改造为村民客厅，碉楼与民居组团改造为民宿酒店；并对208号民居宅院进行改造。
In recent years, with the vigorous development of new rural construction, a large number of traditional villages have been demolished and abandoned on a large scale, and village renewal has followed the old road of urban renewal. Among them, Tibetan villages are located in remote areas, disaster prevention and poverty alleviation and other factors have led to a large number of large-scale renovation activities, the village's space has been demolished, and the traditional context needs to be protected urgently.This paper studies renovation of Tibetan villages in Northwest Sichuan Province. The research contents and conclusions are as follows:(1) Review the theory and practice of urban and rural renewal. Urban renewal generally presents a trend from large-scale renovation to small-scale progressive renewal, with more emphasis on the integrity of the renovation and public participation. However, rural renewal has followed the old road of urban renewal. Tibetan villages are located in the Three Regions and Three Prefectures, and large-scale renovations occur frequently, and Tibetan villages and cultures are in urgent need of protection.(2) Explore the traditional features of Tibetan villages and dwellings in northwest Sichuan. Based on 30 sets of field surveying and mapping data, explore the location and layout of the village, the overall spatial form of the residential house, the internal spatial structure, the construction technology, the architectural space modeling and the traditional form features of architectural decoration art.(3) Sort out the problems faced by the renovation of Tibetan villages in northwestern Sichuan. Traditional Tibetan villages generally have problems with backward infrastructure, declining traditional style, lack of public space, and low-quality residential houses. According to the scale and location, existing renovations are classified five types，including plant relocation type, near relocation type, original site reconstruction type, near expansion type, original site reconstruction type. They caused different degrees of old village space abandonment, decay of style, and homogenization of new villages.(4) Synthesize the key points of protection and the difficulties of reconstruction, and put forward strategies for the renovation of Tibetan villages in northwest Sichuan. In response to common problems and problems caused by renovation, combined with small-scale progressive renewal theory, this paper proposed methods of village renovation planning and residential house renovation design, including clarifying renovation specifications, establishing evaluation mechanisms , improving infrastructure, repairing traditional scenes and creating public spaces , evaluating current buildings, adjusting the functional layout, improving the physical environment, optimizing the structural system, and beautifying the environment.(5) Based on the strategy of village renewal and reconstruction, carry out the planning and design of the renovation of Mudui Village in Li County. First of all，carry out the overall planning of the village. Secondly，transform the public sun dam into a villager ’s living room，and transform the watchtower and residential group into a watchtower hotel. At last，carry out the renovation of No. 208 residential house.
