The Study of the Interaction between Han Dynasty and the Northern World.

汉朝作为中国世界与北方世界有着各种各样的关系，这种关系在北方边界上表现得很明显。该项目旨在从政治、战争、经济、文化和环境的角度描述各种关系。这个项目由历史、地理和考古学者组成。以环境和城堡为常见材料，分析了汉帝国的北部疆界。这便于我们比较每次分析的结果，促进讨论。在以上分析的基础上，我们试图从两个角度来看待汉帝国的北界。一种是关注区域或网络的广义视角，另一种是关注地方社会的狭义视角。首先，从朝廷的治国方略和地区的联系出发，将北方边疆划分为若干地区，并明确了它们之间的关系。其中一个考虑了发展和交通路线，另一个考虑了城堡城市的分布和制作墓葬的技术。我们研究了这个朝代的执政策略。通过对墓葬分类等级的类比，理清了北部边界地区的界限。之后，我们将其与另一个时代进行比较。在新石器时代对地理特征的利用和建立王朝之前的相互作用方面，我们考虑了区域间的相互作用。这是从广义的角度进行的研究。关于地方社会，我们从空间和群体两个角度进行分析。通过城堡城市和郊区遗址，我们重建了当地社会的空间和由县管辖的区域。通过对人口、发展和迁移、丧葬制度和社会阶层的分析，描述了生活在社会中的群体。这是狭义观点的研究。

Han dynasty as Chinese World and the Northern World had the various relations, which appeared clearly on the northern boundary. This project has the aim to describe the various relations on the point of view of politics, war, economy, culture and the environment. This project consisted of the scholar of history, geography and archaeology. With the environment and the castle city as the common materials, we analyzed the northern boundary of Han Empire. It made easy for us to compare the result of each analysis and to promote the discussion. Based on each analysis, we tried to approach to the northern boundary of Han Empire with two viewpoints. One is broad view concerned the regions or broad network, the other is narrow view concerned the local society.First of all, concerning the governmental strategy of the dynasty and the bond of the regions, we divided the northern boundary area into some regions, and made clear the relations of them. One considered the development and the traffic route, another considered the distribution of castle cities and the technique of making the burials. We studied the governmental strategy of the dynasty. With the analogy of classified rank of the burials, it cleared the bond of the regions on the northern boundary. After that we compared it with another age. Concerning the utilization of geographical features and the interaction in the Neolithic age before establishing the dynasty, we considered the interaction of the regions. This is the study from the broad view point.About the local societies, we have two view points of the space and the group for analysis. With the castle cities and the suburban sites, we reconstructed the space of the local societies and the area governed by the prefecture. The group who lived in the society was described with the analysis of population, of development and migration, of the funeral system and of the social classes. This is the study from the narrow view point.
