| As the main representative tribe of the Jurchen in the northeast of the Ming Dynasty,"Four tribes of Lulun" occupied an important position in the development of the northeast frontiers in the middle and late Ming Dynasty.The four have the same family names which are both related and independent,and in the middle and late Ming Dynasty,they successively announced the establishment of their respective state powers and the construction of the city.As the central settlement of the most complete and largest tribe in Northeast China,the construction of Yehe City,Wula City,Hada City and Huifa City not only became the mature symbol of the social system whose tribes are centered on geography.It also represents the highest specification of the Jurchen tribe in the northeastern region,showing the typical characteristics of the construction of the Jurchen city site in the middle and late Ming Dynasty,with certain research space and research value.From the perspective of architecture,this article takes the historical evolution of "Four tribes of Lulun",social development,and the distribution characteristics of the first settlement,the layout of the layout,and the spatial form of the main line,with historical materials,local chronicles,etc.Based on the record,the paper analyzes the historical description of the four tribes and the related descriptions of the four first settlements.At the same time,through the field research and evaluation of the four settlement sites,the literature analysis and the field investigation are combined to systematically examine and discuss the four city settlement forms and the city-go structure.And in the form of a chart to summarize the formation and development of the four first settlements;distribution and structural form;planning and defense system and other aspects of the characteristics and similarities and differences.At the same time,combined with historical,humanities,society,environment and other comprehensive factors,explain the reasons and influencing factors.In the turbulent environment of the late Ming Dynasty,the formation and growth of the first four settlements are closely linked to the internal development and transformation process of the Jurchen society.Because the four development experiences are similar,the four parts of the tribe’s settlement system and the distribution of the city site have strong similarities.The dependence and utilization of the natural environment and the response and emphasis on the social system have become the common content of the four settlements.However,the differences between the social development process and the characteristics of the political system between the four ministries have also led to four diverse settlement forms and institutional characteristics.It can be seen that for the development of the Jurchen settlement in the late Ming Dynasty,it is not only restricted by the objective conditions of the natural environment and geographical conditions,but also subjectively influenced by various aspects such as the social environment and tribal development.The two influence each other and restrict each other,and jointly determine the distribution characteristics and their morphological functions presented by the current city sites.The coping styles of the various ministries have also reflected the wisdom of the Jurchen tribes in using the environment and transforming the environment.At the same time,based on the field research on the location of the site and the interview information of the surrounding people,this paper also focuses on the hot topic of the development of historical and cultural industries,and through the analysis of the status quo and existing problems of the historical and cultural protection of the four sites.From the perspective of historical continuation,this paper discusses the constraints faced by these regions in the modern development and the continuation of historical culture,and then considers the contradiction and turning point between the continuation of local history and culture and the development of local protection. |
