摘　　要：旅游生态安全是区域旅游业发展的基础,开展旅游生态安全研究有利于协调区域生态环境与旅游产业实现可持续发展.研究运用熵权法、Arcgis空间分析法和地理探测器等方法对甘肃省旅游生态安全进行评价,结果显示:研究期间甘肃省旅游生态安全整体呈波动上升的变化趋势,旅游生态安全得到改善和提升,旅游生态安全综合指数由2006年的0.4082上升至2017年的0.6021,安全等级由临界安全上升为较安全;从甘肃省旅游生态安全空间分布图中可以看出,甘肃省旅游生态安全呈现出西北高、东南低,中间高、四周低的空间分布格局;利用地理探测器对影响甘肃省旅游生态安全的主导因子进行探测,发现旅游收入、旅游投资、生态环境质量和生态环境投资等因素是影响甘肃省旅游生态安全的主要因素,在今后的生态安全建设工作中应得到足够的重视.Tourism ecological security is the basis of the development of regional tourism industry.Study of tourism ecological security is conducive to the coordination of regional ecological environment and sustainable development of tourism industry.The tourism ecological security of Gansu Province was evaluated by using the methods of entropy weight,Arcgis spatial analysis and geographic detector.The results show that the overall tourism ecological security of Gansu Province shows a fluctuating upward trend during the study period.The tourism ecological security is improved.The comprehensive index of tourism ecological security increases from 0.4082 in 2006 to 0.6021 in 2017,and the security level increases from the critical level.From the spatial distribution map of tourism ecological security in Gansu Province,the spatial distribution pattern of tourism ecological security in Gansu Province is high in the northwest,low in the southeast,high in the middle and low in the surroundings.The dominant factors affecting tourism ecological security in Gansu Province are detected by geographic detector,and tourism income,tourism investment,ecological environment quality and ecological environment are found.Investment and other factors are the main factors affecting the ecological security of tourism in Gansu Province,which should be paid enough attention in the future construction of ecological security.
