Ecological management is a decision making process that integrates scientific knowledge，local knowledge，needs of decision makers，and is oriented towards unknown and uncertain states. Due to multiple factors，there are serious problems in the integration of science，policy and practice，among science，policy，and practice and become an important barrier to ecologically sustainable development. Therefore，establishing effective communication among the three and developing management tools have gradually become the hot topics of discussion. Based on the review and systematic review of literature，this paper reviews the problems and causes of the integration of the three，and taken Qilian Mountains as an example to illustrate the current situation and problems of ecological resource management in China. The research suggests that encouraging in-depth multidisciplinary intersection，establishing a governmental fault tolerance mechanism，forming a “four-in-one” management system，and implementing adaptive management thinking will help promote effective communication among science，policy and practice，and serve the national strategy of ecological protection and high-quality development in China.
