以福柯为代表的谱系学历史研究法及其理论是当代最为重要的思想理论之一，他对"异"的寻求、对"边缘"的重视、对"永恒"的质疑、对"宏大叙事"的批判、对"偶然性"的肯定，对"多元化"的赞扬等等观察问题的角度、思考问题的方式，使我们看到了一个完全不同于以往的鲜活而丰富多样的历史。本课题正是以这种方法论为基础，通过对广泛分布于我国西南诸省的各类干栏式建筑"差异性"问题的详细调查，进而着重探讨其中的生成衍化关系，着重研究这些"关系"中的异质性元素来自哪里，并在此基础上进一步研究干栏式建筑谱系为何会这样来构建，及其背后的生成机制、模式与规律。进而对干栏式建筑有一个全面深刻的认识。本课题的研究既是一种历时性的研究，又是一种共时性的研究；这种研究是动态的、横向的、联系的、比较的研究。同时，也希望通过本课题的研究，建立一种新的民居研究方法论。

The historical research methods and theory of genealogy，to which Focucault as a representative,is one of the most important idea and theory today. Focucault seeked for "difference", emphasized on ＂edges＂, questioned the "eternal",criticized "grand narrative ",made certain of "contingency",and praised the "diversification". Here, with all of Focucault's these observation angle and way of thinking, we can see a fresh and colorful history, which is totally different from the past. So, the subject is precisely on the basis of this methodology, then we will make detailed investigation on differences of all kinds of pile dwellings ,which widely distribute in the China's southwest provinces. Next we will focus on the origin relationship in it, and figer out where these heterogeneity elements come from,because of these for the genealogy of pile dwellings ,we can make further study why they formed like these,what are their generation mechanisms, modes and laws.And then we can have a comprehensive and profound understanding of pile dwellings. The study is not only diachronic ,but also synchronic,and at the same time it is dynamic, transverse,connective and comparative. What is more, with the project we hope to make a new residential research methodology .
