Analysis On Spatial Mismatch And Vulnerability Evolution Of Tourism-Economy-Ecosystem In The Yangtze River Economic Belt

The Yangtze River Economic Belt,which spans the eastern,central and western regions,is one of the "three major strategies" implemented by the central government.Promoting the development of the Yangtze River Economic Belt is of great significance to the realization of the "two centenary goals" and "the Chinese dream" of great national rejuvenation.Due to the large differences in the development status of the provinces and cities,the imbalances in the tourism industry,regional economy,and ecological environment system in the Yangtze River Economic Belt have become more frequent,the spatial mismatch between the elements of each system has become more prominent,and the degree of vulnerability has become more serious;How to realize the harmonious development and sustainable development of the tourism industry,regional economy and ecological environment in the Yangtze River Economic Belt is the key to the optimization of China’s tourism spatial pattern.This paper takes the Yangtze river economic belt in 11 provinces and cities as the research object,selects 15 years of data from 2003 to 2017,and constructs a tourism-economy-ecosystem spatial dislocation and vulnerability evaluation index from the three systems of tourism industry,regional economy and ecological environment.Firstly,using the spatial mismatch theory,the spatial mismatch index model and contribution model are used to explore the spatial evolution pattern of the provinces and cities in the Yangtze River Economic Belt and the whole area,and the contribution of each province to the spatial mismatch.Secondly,the article uses the vulnerability model and the obstacle model to explore the vulnerability index of all provinces,cities and the whole area in the Yangtze River Economic Belt and the obstacle factors that affect vulnerability.Research showsthat: in terms of spatial mismatch index,Shanghai,Jiangsu,Zhejiang has significantly negative dislocation,other provinces and cities were positively to dislocation,the Yangtze River Economic Belt area of the overall mismatch index showed a trend of decline,but still large of absolute value,the contribution of each region to the overall spatial mismatch index is mainly concentrated in individual provinces and cities,indicating that the reasons for the current spatial mismatch of the three systems in the Yangtze River Economic Belt are concentrated in a few regions.In terms of vulnerability index,except Shanghai,Jiangsu and Zhejiang province,the vulnerability index of other provinces and cities is relatively low.On the whole area,the overall vulnerability of the three regional systems continues to rise,which also shows that the overall vulnerability of the Yangtze River Economic Belt is also concentrated in a few areas.By analyzing the influencing factors that cause the system vulnerability,it can be found that both the obstacle factors of each province and the overall regional obstacle factors are mainly derived from the tourism industry and the ecological environment system.It can be learned that the influence of the tourism industry system and the ecological environment system on the whole vulnerability is more important.Only by maintaining a good balance between the tourism industry and the ecological environment can the vulnerability of the three systems be reduced,so as to better improve the contribution to the regional economy,optimizing layout space mismatch and jointly drive the booming development of the regional economy.Finally,based on the spatial mismatch grade and vulnerability degree of tourism-economy-ecosystem in the Yangtze River Economic Belt calculated,it is divided into four regions,and countermeasures are proposed from the macro and micro perspectives.
