In 2015，the government went on promoting traditional dance protection in the efforts of all parties and had made a lot of achievemeuts. But there are some problems exist，the concept of protection for example. The protection of “original ecological dance” as repeatedly mentioned is still worth thinking. The paper deconstructs the concept from the explanation and the case of “original ecological dance” from the perspective of cultural ecology，to think that from the commercial performances to intangible heritage protection，the “original ecological dance” is the process and result of culture processing，transplantation and reconstruction of cultural reproduction. At the same time，it exists unhealthy tendencies such as nihilism，conservatism and market coercion. The traditional dance heritage protection must abandon the conservative idea of “original ecological dance”，further clarify the protection object and the boundary，establish a sustainable ecological concept，construct a cultural ecological pattern，and pay attention to the dynamic balance between the community residents’ subjectivity，local government management and social organization guidance.
