Research on optimization of post-earthquake restoration planning strategy of Jiuzhaigou world heritage site based on value correlation: from the perspective of heritage site administrators

We conducted a questionnaire survey on heritage site managers to obtain the relationship between post disaster recovery and reconstruction strategies, protected area planning and value objects, and used the information model method to analyze and show the degree difference of this relationship. The research shows that i) cognitive correlation has been built between restoration strategies and all value objects, and the correlative identification complexities are different for different specific strategies. The specific strategy for "scenic spot restoration and industrial development" has the highest level of complexity of correlation identification, ii) the degrees of uncertainty for the value objects to be identified in the restoration strategies are different. The Tibetan villages are identified as the objects with the highest certainty and the lowest fluctuation, iii) the restoration strategies have responded the overall orders of the value object identification in the protected areas. The restoration strategy has more uncertainty and complexity fluctuation than identification of protected areas. Finally, the paper puts forward suggestions for sustainable restoration and development of the heritage sites, including strengthening the correlation between village evolution and heritage values, restoring the systematization of strategies, and planning the connection with overall value objects.
