文章以新疆88个县域单元为例，基于PSR-TSEE评估框架，探讨2000年、2010年、2018年新疆县域旅游社会-经济-生态系统脆弱性的时空演变特征与影响机理。结果表明：时间变化上，新疆县域旅游社会-经济-生态系统脆弱性整体呈现连续下降态势，各子系统脆弱性变化呈现波动特征，其中经济子系统脆弱性最高，生态子系统脆弱性最低，社会子系统脆弱性呈不断下降态势。空间变化上，新疆县域旅游社会-经济-生态系统脆弱性的空间分布呈现“西南高-北部低”特征，其中生态子系统脆弱性呈现“东南低-西北高”特征，经济子系统脆弱性演变格局逐步由全域分布向“南高北低”变化；各子系统脆弱性耦合度较高，各县市协调度差异较大；各县市系统脆弱性具有空间自相关性，相关度略有提升。阻碍新疆县域旅游社会-经济-生态系统脆弱性下降的主要因素为人口密度、单位耕地化肥使用量、城镇化率等，处于不同脆弱性分区的县市，其主要障碍因子及影响程度略有差异。社会经济生态基础条件、旅游业和农业发展是影响新疆县域社会-经济-生态系统脆弱性的主要因素。

The paper takes 88 county-level units in Xinjiang as an example, and based on the PSR-TSEE evaluation framework, explores the spatio-temporal evolution characteristics and impact mechanisms of the vulnerability of tourism socio-economic ecosystems in Xinjiang county-level areas in 2000, 2010, and 2018. The results indicate that: In terms of time variation, the overall vulnerability of the tourism socio-economic ecosystem in various counties in Xinjiang shows a continuous downward trend, and the vulnerability changes of each subsystem show fluctuating characteristics. Among them, the economic subsystem has the highest vulnerability, the ecological subsystem has the lowest vulnerability, and the social subsystem has a continuous downward trend.In terms of spatial changes, the spatial distribution of the vulnerability of the tourism socio-economic ecosystem in Xinjiang counties is characterized by a "high in the southwest and low in the north", with the vulnerability of the ecological subsystem showing a "low in the southeast and high in the northwest" feature. The evolution pattern of the vulnerability of the economic subsystem is gradually shifting from a global distribution to a "high in the south and low in the north" pattern. The vulnerability coupling degree of each subsystem is relatively high, and the coordination degree of each county and city varies greatly. The vulnerability of each county and city system has spatial auto-correlation, with a slight increase in correlation. The main factors hindering the decline in the vulnerability of the tourism socio-economic ecosystem in Xinjiang counties are population density, the amount of fertilizer used per unit of arable land, and urbanization rate. Counties and cities located in different vulnerability zones have slight differences in their main obstacle factors and degree of impact. The basic conditions of socio-economic ecology, tourism and agricultural development are the main factors that affect the vulnerability of the socio-economic ecosystem in county-level areas in Xinjiang.
