EVALUATION ON TOURISM ECONOMY-ECOLOGICAL ENVIRONMENT COMPOUND SYSTEM UNDER SUSTAINABLE DEVELOPMENT GOAL AND ITS INTERACTIVE EFFICIENCY

Currently there are many problems to be solved in ecotourism, like the conflict between eco-tourism development and economic benefits and the immature management model. Achieving the sustainable development of economy and environment has always been the ultimate goal of ecotourism, so research on this topic has strong practical significance. Based on the Bayesian network, this paper evaluates the tourism economy-ecological environment compound system under the sustainable development goal, and studies the interactive efficiency of the subsystems. First, the relationship between tourism economy and ecological environment was analysed, and based on the analysis results, a coordination model and a coupling coordination model of the composite system were constructed, Then, a coordinated development mechanism was analysed and constructed for the compound system, and a scientific index system was given for the evaluation of coordinated development degree. Finally, a compound system coordinated development evaluation model was constructed based on the Bayesian network so that dynamic evaluation can be performed on the compound system. The experiment verified the effectiveness of the proposed algorithm and model.
