黄河流域省(区)旅游-经济-生态系统脆弱性时空演变及障碍因素分析

Analysis on the Spatio-Temporal Evolution and Obstacle Factors of Tourism-Economy-Ecosystem Vulnerability in the Yellow River Basin Provinces(Regions)

基于2011-2020年黄河流域省(区)的数据,采用脆弱性指数探讨黄河流域省(区)旅游-经济-生态系统脆弱性时空演变特征。结果表明,黄河流域省(区)旅游-经济-生态系统综合脆弱性整体呈现下降趋势,高等级脆弱性类型减少,较低等级脆弱性类型增加;旅游子系统脆弱性整体变化不大;经济、生态子系统脆弱性呈下降趋势,脆弱性类型由强脆弱性向较低脆弱性转变。在空间上呈现出由黄河上游到下游脆弱性逐渐降低的态势。采用障碍度模型探究脆弱性影响因素,发现旅游子系统对于黄河流域省(区)旅游-经济-生态系统脆弱性下降的阻碍作用较大。

Based on the data of provinces(regions)in the Yellow River Basin from 2011 to 2020,this paper used the vulnerability index to explore the spatio-temporal evolution characteristics of the vulnerability of tourism-economy-ecosystem in the provinces(regions)in the Yellow River Basin.The results show that the comprehensive vulnerability of tourism-economy-ecosystem in Huanghe River province(autonomous region)presents a downward trend as a whole,and the vulnerability types changes greatly,with the high-grade vulnerability types decreasing and the lower-grade vulnerability types increasing.The overall vulnerability of tourism subsystem has little change,but the vulnerability of economic and ecological subsystems shows a downward trend,and the vulnerability type changes from strong vulnerability to low vulnerability.From the spatial perspective,the vulnerability gradually decreases from the upper reaches of the Yellow River to the lower reaches.The barrier model was used to explore the influencing factors of vulnerability,and it is found that the tourism subsystem has a greater hindering effect on the decline of vulnerability of tourism-economy-ecosystem in the provinces(regions)of the Yellow River Basin.
