摘要
以长江经济带干线流域为研究单元,基于旅游产业系统环境脆弱性概念界定和"敏感性—应对能力"框架构建指标体系,运用脆弱性和障碍度模型,探讨了区域旅游产业系统环境脆弱性时空演变特征,并对障碍因子进行诊断识别,研究发现:(1)时间维度,流域旅游产业系统环境敏感性与应对能力呈"并驾齐驱"式同步增长态势,整体脆弱性表现为"震荡起伏"式有序下降,且时序分异特征鲜明。(2)空间维度,流域旅游产业系统环境脆弱性具有显著的动态演替性,下游环境高风险区呈现空间集群特性,但区段脆弱性程度不断下降,中游脆弱性呈"先降后升"演变走势,上游脆弱性具有较强的稳定性,指数值波动变化幅度相对较小。(3)长江经济带旅游产业系统环境脆弱性时空变迁是流域多重人为扰动共同作用的结果,城镇化与工业化、投资与消费激增和大规模旅游开发活动是引致流域旅游产业系统环境敏感性增加的主要因素,而制约旅游产业系统环境应对能力提升的主要障碍因素则表现为公共交通与生态建设、科技与教育水平及区域经济发展实力等。
Taking the trunk stream region of Yangtze River Economic Belt(YREB) as the research area and based on the concept definition of environmental vulnerability of tourism industry system,this paper constructs its index system under the framework of "sensitivity-response ability",discusses the temporal and spatial evolution characteristics,and identifies the obstruction factors with the use of vulnerability and accessibility models. The study finds that: 1) From the angle of time dimension,the environmental sensitivity and coping ability of the tourism industry system in the YREB are growing simultaneously. The region’s overall vulnerability is orderly declining in volatility and the timing differentiation is distinct. 2) From the angle of space dimension, the environmental vulnerability of tourism industry system has a remarkable dynamic succession and is decreasing. the high-risk areas of environment in the downstream YREB are distributed in clusters, the environmental vulnerability in the midstream YREB decreased and then increased, the environmental vulnerability of tourism industry system in the upstream YREB is with strong stability,and the fluctuation range of the index value is relatively small. 3) The temporal and spatial changes of the environmental vulnerability of tourism industry system in the YREB are the result of interaction of multiple human disturbance factors. Urbanization and industrialization,the surge of investment and consumption and the large-scale tourism development activities are the main factors that promote the increase of environmental sensitivity of tourism industry system, the obstruction factors to the improvement of the environmental response capacity of tourism industry system mainly include the following aspects,such as the public transportation and ecological construction,the level of science-technology and education as well as the regional economic strength.
