An Exploration on the Value Evaluation Method for the Heritage System of the Third-Front Construction Under the Holistic Protection Idea: Taking Hubei Province as an Example

As a 'Chinese-style’ industrial heritage that witnesses technological innovation, promotes historical progress, and reflects multiple values, the reasonable preservation and continuation of the heritage built by the third-front construction is the purpose and significance of this study. The number of industrial building sites left over from the third-front construction period is huge, and not all of them have preservation value. Therefore, the idea of holistic protection has become the primary idea in the context of land incremental conversion and urban organic renewal. Under the background, the paper studied the series of elements of the built heritage of the third-front construction to clarify the four-in-one value system of architectural value, environmental value, intangible value and contemporary value, so as to establish a systematic value evaluation system, and introduce oral history and fair value range to jointly determine the rates of evaluation factors. Empirically, the system could provide conditions for vertical and horizontal, single and multiple comparisons for the evaluation results. It could not only horizontally compare and analyze the value differences of different plant areas, but also vertically compare the relative importance of various values of the same plant area, and ultimately guide the integrity protection of third-front construction, also provide a tool and method for transforming the industrial'rust belt’ into the 'show belt’ of life in China’s urban renewal in the future.
