SD-based Guilin Tourism Sustainable Development Evaluation And Simulation Research

Tourism is a happiness industry that affects people's livelihood,and is a driving force for the vigorous development of primary and secondary industries.Since the new era,China's economic development has made great achievements,people's living standards have improved significantly,people's pursuit of spiritual happiness has become increasingly prominent,and the tourism industry has shown a "crowded" supply trend driven by the "crowded" demand.Flourishes in its dual structure.According to statistics from the National Tourism Administration,the total national tourism revenue in 2019 will reach 10.94 trillion yuan,with a contribution rate of 11.05% to GDP.The tourism industry will provide 79.87 million jobs,accounting for 10.31% of the national employment population.Tourism has become a strategic pillar industry of our country.However,the development of the tourism industry still suffers from the problems of low construction quality of scenic spots,inefficient development of tourism resources,pathological ecological environment,serious damage to landscape resources,insufficient supply-side development models and insufficient innovation of supply products,which restrict the sustainable development of the tourism economy.In March 2018,the State Council issued the "Guiding Opinions on Promoting the Development of Global Tourism",which further emphasized the importance of sustainable development of the tourism industry and the urgency of changes in the methods and methods of tourism development.Guilin,as the first batch of national sustainable development agenda innovation demonstration areas and tourism development cities,takes Guilin as the research object,analyzes the development of tourism,and finds the path for sustainable development of tourism,so that tourism of Guilin can be used as a development paradigm for tourism.It has important theoretical and practical significance to promote the whole region and the whole country.This article takes tourism of Guilin as the research object,and uses the improved DPSIR model to introduce the driving force,carrying capacity,status,impact and response subsystems to supplement the definition of sustainable development of tourism.The improved TOPSIS model based on entropy weight and grey relation was applied to the sustainable development evaluation of Guilin tourism.Using system engineering principles,a system dynamics model is constructed,and the sustainable development model of Guilin tourism is selected and relevant suggestions are made.The results show that the development trend of Guilin's tourism industry is slow and the development momentum is insufficient during the study period;the tourism investment ratio has a direct role inpromoting the sustainable development of Guilin's tourism industry;ecological optimization has a significant positive effect on the sustainable development of Guilin's tourism industry;The most suitable for the sustainable development of Guilin tourism.Based on the results of empirical research,this article proposes strategies for sustainable development of Guilin tourism from five aspects: strengthening the construction of tourism infrastructure;ensuring high-quality tourism development;increasing tourism visibility;ensuring steady growth in tourism investment;and accelerating effective transformation.
