From May 13 to August 11,2019, the Cultural Relics Exhibition,"the Splendor of Asia 一 an Exhibition of Asian Civilizations", is opened at National Museum of China. Those exhibited are 45 1 cultural relics from 47 Asian countries and another 2 countries with ancient civilizations, i.e., Greece and Egypt. Among them were 1 09 Chinese relics, including Bronze Statue of Yi, Changxin Palace Lamp and other national treasures.展开更多

Then it analyzed the scientific value, artificial value, and historical value of cultural relics based on the angle of landscape. All these values had been changed and were indicated cultural value, aesthetic value and resource value as new values. The cultural value included identification with culture, inherited culture and educational value. The content of aesthetic value contained visual aesthetics and enjoyment. The resource value which was composed of the essence, space-time and scarcity, was revealed economic value, which was composed of environmental value and tourism value. In the following, the values of landscape and the new identified values of cultural relic were compared together to discover the connections between them. Finally, the new values of cultural relic were established under the angle of landscape which was composed of 4 degrees.展开更多
