as an important part of ecological civilization，ecotourism needs to produce greater results in providing more high-quality ecological products and meeting the growing and beautiful needs of the people. At present，the ecotourism industry in the three northeastern provinces is in a critical period of pressure superposition and weight-bearing. From the development status of ecotourism in the three northeastern provinces，there are not only achievements and characteristics，but also problems such as vague development orientation and serious homogeneous competition.
