However, at the present time, this method has failed to achieve due results for various reasons. The author further elaborated on this point and pointed out that in order to make the small-scale reconstruction in cities become an active factor in urban development and construction. There must be corresponding countermeasures for different types of cities to use for reference and practice in their renovation activities.
