Study On Spatial-temporal Pattern Evolution Of Ecological Security In Tourism Industry Ecosystem

As the fastest growing industry in the world,tourism is one of the important ways to promote the development of China's regional economy and urbanization,which has an important position and role in the national economy and has become an important strategic pillar industry.The rapid development of tourism industry in Liaoning Province has promoted regional economic growth and social progress,but at the same time,tourism activities and tourism development have caused regional environmental damage and pollution,and the carrying pressure of tourism ecological environment has continued to increase,which affects and restricts the sustainable and healthy development of tourism in Liaoning province.Therefore,in order to promote the relationship between the development of tourism industry and ecological environment protection,it is necessary and practical to maintain and promote the safety and health of tourism industry ecosystem,which is of great guiding significance to the eco-development of tourism industry in Liaoning province and northeast China,and can provide theoretical basis and decision reference for government to make relevant policies.Based on the relevant index data of 14 prefecture-level cities in Liaoning province in 2000-2015,this study analyzed the ecological security status of tourism industry ecosystem in Liaoning Province.The specific contents and main conclusions of this study are as follows:(1)Through the discussion of ecosystem and industrial ecological theory and the review of research progress at home and abroad,this paper defines the concept of tourism industry ecosystem,and considers that tourism industry ecosystem refers to the common existence of tourism industry population in a certain space and time.The unified whole that the tourism industry system and the natural environment and the social environment interact and depend on each other.Based on the structure of individual,population,community and system of natural ecology,the structure of eco-system of tourism industry is analyzed.(2)In the study of ecological security of tourism industry ecosystem in Liaoning Province,this paper establishes the Ecological Security Evaluation Index System of tourism industry ecosystem through PSR model,and uses entropy method to assign weights to each index,and calculates the ecological safety index of tourism industry ecosystem in Liaoning Province according to the weight.According to the type of time evolution,the ecological security evolvement types of different urban tourism ecosystem are different,although the ecological security status of the tourism ecosystem in Liaoning Province is generally improved,but it is not always improving,it can be divided into the continuous growth type and the first growth and then the lower type.Liaoning Province in the formulation of relevant policies,to local conditions,fully consider the characteristics of different cities.(3)In the spatial distribution law,the ecological security of tourism industry in Liaoning Province has no obvious distribution pattern in 2000 years,and the whole province belongs to risk level and sensitive level.In the 2005,Shenyang and Dalian's ecological security superiority was outstanding,most of the province belonged to the sensitive level;In the 2010,the cities with high ecological security rank are gradually concentrated in the eastern part of Liaoning Province,and in the 2015,the cities with high ecological security rank are located in the eastern and southern parts of Liaoning Province,and the ecological security level is low.(4)Comprehensive index of eco-security of tourism industry ecosystem in Liaoning Province,the security index of the state system and the security index of the response system are all on the rise,only the safety index of the pressure system is generally decreasing,which shows that the ecological pressure of Liaoning Province is lower and the ecological environment condition is improved while the tourism industry is developing.However,the value of eco-safety pressure index is still very high,and the eco-system of tourism industry in Liaoning province still faces serious ecological security situation,which needs attention and solution urgently.
