With the development of city, more and more people are aware of that like the traditional building, the historical block should be protected because of the historical deposits. However, for a long period, more time are spend on material conservation, such as the archaeological studies and restorations of historical vestiges and their surroundings, while little is spend on spiritual aspects, such as the research on folk custom, social environment and humane studies. From an international academic communication-the conception design of Ciqikou, it is suggested that the conservation of historical block is different from that of single building. In order to preserve the integral environment of historical block, the dwelling environment of local people should be taken into account. This paper aims at comparison of and discussion on the protection and development of historical block both at home and abroad.
