Abstract Tourism ecological security is an important indicator of the sustainable development of tourist destinations. Considering the complete embodiment of human social factors, the DPSIRM-SBM Model is cited and improved. Taking tourism ecological security of the Yangtze River Economic Belt as the research object, the characteristics of temporal and spatial evolution and its influencing mechanism are analyzed, aiming at making a scientific, comprehensive and systematic evaluation. It is found that the tourism ecological security of the Yangtze River Economic Belt is between sensitive and general security levels; Formed a spatial pattern with strong two ends and weak middle; The security advantages at the junction of provincial administrative regions are obvious; Regional differences first increase and then decrease, which accords with the theory of unbalanced growth;In terms of spatial agglomeration, the main type in YREB as a whole shifted from an initial downstream high-value agglomeration to a midstream low-value agglomeration; Sustainable tourism is affected by comprehensive factors, economic growth is not the main driving force, the construction of ecological civilization is very important.
