| With the improvement of living standards,tourism has gradually become one of the main pastimes for people,which is often accompanied by the increasing demand for tourism and the increase in tourist flow,which also brings different degrees of hidden dangers to the ecological security of tourist places.Therefore,promoting the coordinated development of tourism economic benefits and ecological environment,and optimizing the ecological security level of tourism places have become key issues in tourism development research in various regions.As a typical ecologically fragile area in the northwest inland of the Hexi Corridor,its tourism ecological security is an effective guarantee for the sustainable development of local tourism,and it is also the basis for the Hexi Corridor to practice ecological civilization construction.Based on this,this paper takes the five prefectures of Hexi Corridor,Zhangye,Wuwei,Jiuquan,Jiayuguan and Jinchang as the research area,and first constructs the tourism ecological security evaluation system of Hexi Corridor based on the DPSIR model,and uses the entropy value method to empower the indicators in the system.Secondly,according to the comprehensive index,the ecological security status of tourism in the Hexi Corridor from 2011 to 2020 was analyzed and evaluated,and the temporal and spatial evolution law was visualized.Finally,the obstacle model was used to diagnose the obstacles that inhibited the improvement of tourism ecological security in Hexi Corridor.The results of the study showed that:(1)From the perspective of the time evolution characteristics of tourism ecological security in Hexi Corridor,the comprehensive index of tourism ecological security in Hexi Corridor has always been between 0.4-0.5 in the decade from 2011 to2020,realizing the transition from sensitive level to critical safety level,but the overall presentation level is still in the middle and low stage,and the state of tourism ecological security is not optimistic.The change trend of the comprehensive index of tourism ecological security in the five cities is small,and the overall trend is steadily increasing,and there is still sufficient room for the improvement of the comprehensive index of tourism ecological security.(2)From the perspective of the spatial evolution characteristics of tourism ecological security in Hexi Corridor,the tourism ecological security of the five cities in Hexi Corridor is mainly based on critical safety level,and the spatial distribution shows the characteristics of "high in the west and low in the east,and the critical safety level is widely distributed".(3)From the perspective of the obstacles inhibiting the improvement of tourism ecological security in Hexi Corridor,the state system and the influence system mainly hindered the local tourism ecological security with the greatest obstacles,while the pressure system had less obstacles,and had been in a low obstacle mode.In the index layer,the three factors of tourism revenue,per capita tourism income and tourism revenue to GDP have always ranked in the top three,in addition to the proportion of energy conservation and environmental protection expenditure,per capita green space area,tertiary industry proportion,the number of vocational and higher education students per 10,000 people,the comprehensive utilization rate of solid waste and other factors and obstacles are very prominent.From the perspective of the barrier factors in various cities,although the dominant obstacle factors have not changed much,there are still significant differences between different cities and cities.(4)In order to improve the level of tourism ecological security in the Hexi Corridor,from the optimization of tourism ecological driving force;alleviating ecological pressure on tourism;upgrading the ecological status of tourism;promoting the ecological impact of tourism;Five aspects of improving tourism ecological response are proposed to promote the safe development of eco-tourism in the Hexi Corridor. |
