| 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 pressure-status-response (PSR) model,we chose Guangdong Province as the sample and established the evaluation systems of tourism eco-security,then applied entropy weight and synthetic evalua tion model to analyze spatiotemporal variation characteristics of tourism eco-security in Guangzhou,finally adopted obstacle degree model to diagnose the main limiting factors on tourism eco-security.The results are shown as follows.(1) During the period from 2005 to 2014,the comprehensive tourism eco-security index showed the rising trend,and the security level raised from the risk grade to the relatively safe grade.(2) Besides Jieyang,tourism eco-security levels of other 20 cities have improved from 2005 to 2014.(3) From the index layer,the biggest obstacle factor of tourism eco-security in Guangdong Province is urban living sewage treatment from 2005 to 2008,the biggest one is solid waste discharge from 2009 to 2010,and the biggest one is urbanization rate from 2011 to 2014,and the main influence factors shifted from factors of environmental economy to the ones of social economy.From the point of target layer,now pressure system becomes the main factor to hinder the promotion of tourism eco-security level in Guangdong Province. |
