【摘要】：以广东省为研究对象,基于压力—状态—响应(PSR)模型构建旅游生态安全评价指标体系,运用熵值法和综合评价模型分析广东省旅游生态安全的时空变化特征,并采取障碍度模型诊断旅游生态安全的主要限制因子。结果表明:(1)2005—2014年,广东省旅游生态安全指数总体呈上升的趋势,安全等级从风险等级提升至比较安全等级;(2)2005—2014年,除揭阳外,广东省其他20市的旅游生态安全水平均有所提升;(3)从指标层来看,2005—2008年广东省旅游生态安全的最大障碍因子是城镇生活污水处理率,2009—2010年其最大的障碍因子是固体废弃物排放量,而2011—2014年其最大障碍因子则是城镇化率,主要影响因子由环境经济方面过渡到了社会经济方面。从目标层来看,目前压力系统成为阻碍广东省旅游生态安全水平提升的主要因素。
[Abstract]:Based on the pressure-state-response model, the evaluation index system of tourism ecological security was constructed in Guangdong province. The temporal and spatial characteristics of tourism ecological security in Guangdong province were analyzed by entropy method and comprehensive evaluation model. The barrier model was used to diagnose the main limiting factors of tourism ecological security. The results showed that the tourism ecological security index of Guangdong Province showed an upward trend from 2005 to 2014, and the security level increased from the risk level to the comparative safety level from 2005 to 2014, with the exception of Jieyang. The level of tourism ecological security in other 20 cities in Guangdong Province has been improved. From the index level, the biggest obstacle factor of tourism ecological security in Guangdong Province from 2005 to 2008 is the treatment rate of municipal domestic sewage and its biggest obstacle factor in 2009-2010 is the discharge of solid waste. In 2011-2014, the biggest obstacle factor is the urbanization rate, the main influencing factor is from the environment and economy to the social economy. From the target level, the pressure system has become the main factor that hinders the promotion of the tourism ecological security level in Guangdong Province.
