Questionnaires and interviews were employed to collect data from those whose careers and lives are affected, and were affected, by the buildings. The investigation reveals that people show significantly different attitudes towards the two types of buildings and place more value on old buildings. People particularise their liking for old buildings associated with traditional values, aesthetic quality and conformity to surroundings whereas indicates their disliking for new ones with changed values from tradition to modernity, unsound administrative management and poor respect for surroundings. It is concluded that traditional ideology tends to be well expressed by the old buildings but poorly by new ones. It is accordingly suggested that ideology should be taken more into account in new building projects in Mount Emei.展开更多

It is found that the problems in relation to old and to new buildings are different. Then, authorities that can combat problems of old and new buildings are in general different. After that, in relation to old buildings, architectural design institution and religious unit are considered to be able to deal with the problems resulting from function and utilisation and the Mount Emei Authority to those from organisation and management. In relation to the new, the planning institution is believed to be the most authoritative to tackle surrounding and traditional value problems while the architectural design institution is well placed to resolve aesthetic problems. Finally, both old and new buildings require improved powers, policy, administration and organisation to combat the problems although financial resources are emphasised for the old buildings and improvements in planning and architectural design for the new ones.展开更多
