文章基于高质量发展理念,构建旅游产业—区域经济—生态环境系统评价指标体系,以西北五省区为例,合成各省区三系统2010年—2019年综合发展指数,评价各省区耦合协调发展水平。结果表明：2010年—2019年间,西北五省区旅游业综合发展水平提升较快,2019年指数值高达0.87;区域经济综合发展水平较低,指数均值在0.44~0.54间浮动;生态环境综合发展水平呈上升态势且各省区趋于一致。三系统耦合协调度从2010年的濒临失衡提升到2019年的良好协调。此外,剪刀差分析表明,旅游产业与区域经济、旅游产业与生态环境、区域经济与生态环境两两系统间演化速率差异逐步缩小,呈现协调演化趋势。西北五省区应基于区域一体化协同发展理念,利用区位及政策优势大力推动经济发展和基础设施建设,加强生态保护与环境治理,努力形成区域互助共生、互利共赢的友好发展局面。

Based on the concept of high quality development, this paper constructs the evaluation index system of tourism industry,regional economy and ecological environment. Taking five provinces and regions in northwest China as an example, the comprehensive development index of each region and system from 2010 to 2019 was synthesized to evaluate its coupling coordination degree. The conclusions are as follows: during the study period, the tourism industry grew significantly, with the index value of up to 0.87 in 2019; the comprehensive development level of regional economy is relatively low, and the average value of the index fluctuates within 0.44 to 0.54. The overall development trend of ecological environment in all five provinces and regions is consistent. The coupling coordination degree of the three systems was nearly out of balance in 2010 to good coordination in 2019 with the index rose from 0.47 to 0.83. The scissors difference analysis shows that the evolution rate gap between the two systems is gradually narrowing, and there is a trend of coordinated evolution. In view of this, it is of great necessity for these five provinces and autonomous regions to take their advantages of location and policy to promote economic development and infrastructure construction based on the concept of coordinated development of regional integration, strengthen ecological protection and environmental supervision and governance, and create a friendly development featuring regional mutual assistance, symbiosis and mutual benefit.
