Quantitative evaluation based on the analytic hierarchy process for the degree of deterioration of Guangyuan Thousand-Buddha Grottoes of the Tang Dynasty in Sichuan
Guangyuan Thousand-Buddha Grottoes are of great value in researching the spread of Buddhism in China.To explore a scientific evaluation method for the degree of deterioration,we selected 20 grottoes of the middle Tang Dynasty in Guangyuan Thousand-Buddha Grottoes as survey objects.The traditional deterioration investigation was made and the analytic hierarchy process(AHP method)was applied to build a system to calculate the weights of 15 common types of deterioration and to evaluate the degree of deterioration of the grottoes.The result shows that each of the 15 types of deterioration has its own weight on affecting the preservation condition of the grottoes and that it could be classified into two categories—structural deterioration and the non-structural deterioration.By contrast with the realistic condition,the calculation result could reflect the preservation condition of the grottoes quantitatively.The result offers a quantitative basis to determine the priority order of grotto conservation,and verifies the feasibility of the AHP method in helping the conservators identify the major types of deterioration or judging the order of conservation.The research proposes a quantitative evaluation method for the degree of deterioration of grottoes,which could lay a foundation for further conservation of grottoes.
