Based on the protection of local Qianshan area culture, taking Hekou ancient town street of Ming and Qing Dynasty as an example, with the construction of place spirit and sense of belonging as the primary goal, and combining the history and culture of the city, the current situation of the streets and the characteristics of the buildings, this paper put forward the relevant renovation measures to provide a kind of thinking for the refined and rational renovation of the blocks in the future.展开更多

文摘The renovation of historical blocks often stays at the material level of buildings, ignoring the deeper spiritual level, which can not arouse people’s sense of belonging to the city memory. Based on the protection of local Qianshan area culture, taking Hekou ancient town street of Ming and Qing Dynasty as an example, with the construction of place spirit and sense of belonging as the primary goal, and combining the history and culture of the city, the current situation of the streets and the characteristics of the buildings, this paper put forward the relevant renovation measures to provide a kind of thinking for the refined and rational renovation of the blocks in the future.
