Research on Quantitative Evaluation Method for Morphological Resilience of Historical Blocks—Taking the Historical and Cultural Blocks in the Xinanyu and Dongnanyu Subdistricts of Luoyang City as an Example

At present, the research on the resilience of historical blocks is mainly focused on the theoretical interpretation, and lacks the scientific and complete practical approach to quantify the resilience. For the purpose of protecting the morphology of historical blocks, the resistance of morphology is the main body of quantitative evaluation of the morphological resilience. On the basis of analyzing the feasibility of combining Conzen’ s morphological framework with the resilience theory, a quantitative evaluation method for the morphological resilience of historical districts was constructed, which took the division of “morphological resilience regions”as the core. Four morphological resilience indexes including road system connectivity, block modularity, land use function diversity and building texture robustness were used in the evaluation. Finally, weighted overlay was used to obtain the regional map of historical blocks’morphological resilience, which was used to reflect the resilience of different morphological types. On this basis, five types of morphological resilience management units are further divided according to the style type and the strength of resilience. The ultimate goal is to realize the meticulous protection and management of the morphology of the historic district.
