The results show that the whole Wangfu group in Ming Dynasty has been affected to a certain extent, among which the multi-storey buildings built after 2010 are the main factors affecting the site protection; the influence of archaize buildings has a deep concealment; the area of self-built residential buildings will be the key object of early intervention in the future.
