本论文的实践和研究建立在“美丽乡村”运动的大背景之下，也是对当下新农村建设中传统村落该如何更新与发展所做的一次尝试性的回应。在城市化和现代化的进程中，我们的传统乡村应该找准自身在发展过程中的位置，从向传统的“城市化”思想靠拢过渡到“乡镇化”的切入点，保留自身特色，进而在可持续发展的前提下实现更新和发展。传统乡村是具有一定的经济和社会结构，在此基础上的社会意识形态、传统文化、生活方式的载体，是我们人类文明发展的宝贵财富。尽管现有的村落保护和发展问题越来越受到人们的关注，也有越来越多的村落保护更新项目在逐步实施进行。但这里面仍存在诸多不足和缺陷。其一，关注点还是主要集中在自然和人文资源都比较突出的村落，或者是开发价值较大的村落。对于那些分布在我国大部分地区的乡村地区，这些乡村资源条件较为一般，但它们同样承载特定的乡村生活的特质，对地区而言都有着特殊的意义。这类传统乡村的改造更新同样值得我们去关注。其二，现有的传统村落的保护和更新的方式较为单一，往往是采取至上而下规划的方式实现，过分“理想化”，有些地方通过“仿古”等方式再造传统的历史村落，某种程度上也不大符合村落发展的需求。我们要保护的是村落的聚落形态和空间特质，而不是以一种静止的观点去对待我们的传统村落，忽略其当下的意义和可能。其三，现有的一些建筑师和艺术家在乡村地区所从事的乡村实践有着很好的效果，但其文化意象过于浓厚，也很难有普遍的经验和意义，但其对待场地的态度和方法值得我们学习借鉴。张家桐村保护更新项目所要寻找的是对当下传统乡村发展的一种探索，既不是回归传统的村落本身，也不是对现有城市郊区聚落的粗劣模仿，而是期望寻找到一条合理的道路，以一种适当的方式探讨当下传统乡村的更新改造。建立在该项目的研究，在对张家桐村现有条件充分认识的基础上，以一种直接的方式，探讨“微介入”的更新设计策略。并且以笔者所参与的张家桐主街的更新改造设计为论文阐述的重点，分析如何根据场地的需要和空间特质，以一种适时适度地方式进行改造设计。希望能够提炼一些关键词和方法，对以后的传统乡村的改造更新提供一种新的方式，也对建筑师介入下的乡土实践提供一些经验。

The practice and research of this thesis is set up in the background of “Beauty Village”, as a trying respond to the topic that how to develop and renewal the traditional villages in the contemporary rural areas in China. In the process of the urbanization and modernization, the right position in the development should be retrieved by our traditional villages by preserving the original characters and developing in a sustainable way.Traditional villages acting as a load of traditional culture, life style and social ideology based on the specific economic and social structure, are the precious fortune for our civilization. Though more and more attention have been paid to the protection and renovation of traditional villages, there exists kinds of deficiencies. First, the focus point still concentrates in the outstanding villages which have plenty of the cultural and historical heritages, as well as the high value of development. For the majority of other rural areas without exceptional values, they still have their specific characteristics of village life, which is meaningful to the specific region they locate in. The renovation of these villages should be paid more attention to. Second, the existing way to preserve and renewal our villages is too banal and idealistic with the up-to-bottom planning and practice. In some places, people take the imitation action to rebuild the traditional village. To some extend, it doesn't meet the requirement of the development of villages. We can’t hold the static point of view to treat our traditional villages. We have to take account of the current situation and possibilities of the villages, preserving the prototype and spatial scale of villages. Finally, now the rural projects done by some of the architects and artists do have a good feedback. However what they have done are far more than general, which is really hard to promote. We need to learn from their attitudes towards the site and the genius loci.The renewal project of Zhangjiatong is a kind of exploration towards the current development of traditional villages. It is neither the return to the traditional village itself, nor the rough imitation of the suburban area. We pursue for searching a reasonable way to develop traditional villages.Based on the sufficient data of the field research in Zhangjiatong, we introduce “subtle intervention”, as a main strategy to renovate the village. The renovation of the main street in Zhangjiatong which the author attends in will be the key case in this thesis. The author discusses about how to analysis the demand of the site and the specificity of the space, how to intervene into the village in a proper way. The author hopes to be able to abstract some of key words, providing a new methodology for the renewal of traditional villages, as well as some of experience for the architects and their rural practice.
