Research of the Historical Blocks Renewal Based on the Numerical Analysis

Basing on the numerical analysis of historical blocks, the article analyzes the main problems in renewal firstly, and explores the factors that make historic blocks lack of vitality in the transformation of the update process, then establishes historic blocks dynamic elements system. Finally, puts forward the ways of revitalizing historical blocks vitality from the three levels belong integration of street space, transportation system and the historical context, in order to help the construction of related projects in the future.
