Abstract:Historical environment is the key element to shape urban characteristics and highlight urban culture. In recent years,the conservation and regeneration of historical environment have become the focus of urban renewal. In the recent research results,there are few studies about the post occupancy evaluation of the conservation and regeneration strategies adopted for the historical environment. Many existing cases are difficult to support the followup protection through the evaluation of the regeneration strategies. Xiannong block,a typical modern historical environment case in the central urban area of Tianjin,was selected as the research object. The historical environmental conservation and regeneration strategies adopted in Xiannong block were evaluated by conducting public surveys, establishing an evaluation system and performing qualitative and quantitative analysis. The advantages of the protection of the Xiannong block in terms of artistic aesthetics,public awareness,operation and management planning,as well as the current problems such as the lack of supporting infrastructure resources in the surrounding area were summarised. The aim of this paper is to provide basis and reference for the future development direction of Xiannong block through the reintegration and reallocation of current resources.
