By sorting out the development process of heritage protection, it analyzes the teaching tasks and problems in the new era. Based on the discipline platform(T-M-C), it explores the way of multiple integration, and puts forward the strategy of constructing the knowledge community of the teaching team of landscape architecture heritage protection, with a view to cultivating professional talent for landscape architecture heritage protection in China, and contributing to the construction of beautiful Chinese ecological civilization.
