Under the traditional static protection mode that advocates controlling and stresses no change to the original, the central historic block in Baoding is facing some new problems such as the setting back of physical environment, isolation from the urban development and imbalance of the regional economical development. Based on investigation and analysis, the goals and dynamic conservation strategy were proposed for central historic block. The strategy took the dynamic conservation theory, in which the holistic protection and sustainable development were the features, as theoretic tool. And from urban planning, urban administration, society economic growth, urban space design and historic buildings protection aspects, the relationship between protection, renaissance and development were studied with the dynamic conservation strategy.
