Perspectives on the cultural heritage conservation and development
文化遗产保护与开发的思考

The contradiction between economic development and cultural heritage conservation is common everywhere. On the one hand, tourism can not be developed at the cost of destroying rare cultural relics while on the other , we shouldn't stop developing tourism for the sake of cultural heritage conservation.Here we reiterated the "China Policy", which is the requirement for fulfilling human culture succession and sustainable development. In grotto culture protection, some problems have been solved, such as the harm of crowded people to fresco and painted sculpture, wind and sand erosion, etc. But there are many other social and natural environmental problems, one of which is the erosion of flood to the base of grotto. Ancient city sites are helpful for paleo-environmental reconstruction. The abundant information from archeological excavation, together with natural environmental change and culture spreading, might contribute to a new way to explain and demonstrate ancient cultures. Explaining the enigmas of many ancient city sites also need to start with virtual paleo-environment. The reconstruction of old buildings should follow the principle of "repair as their origins". Besides, adapting the old buildings to modern environmental and ecological functions should also be considered. New technology and material can be used in some cases. There are several successful examples of applications of remote sensing monitoring to archeological excavation and cultural heritage conservation. We suggested that grid technology used in the field of archeology should be further popularized. And multi-level grid management information systems should be built up to improve cultural heritage conservation and development.
