The country＇s architectural heritage conservation activity is an integral part of the world conservation movement. This paper gives a general introduction of the movement in China from four aspects： （1） history; （2） important conservation projects assessments; （3） new ideas and principles being debated and discussed; and （4） issues facing the movement. The present paper summarizes the essential character of the movement in China and highlights the importance of suDoorting and Drotecting this movement.展开更多
