By selecting Guangdong province as an example , this paper established the comprehensive evaluation system of tourism economy and ecological environment , and applied synthetic evaluation model and coupling coordination model to estimate the comprehensive index of both tourism economy and ecological environment , and to analyze their coordinated relation.The re-sults were shown as follows:( 1) From 2005 to 2014, the comprehensive index of both tourism economy and ecological environ-ment in Guangdong province revealed a rising trend, and there was a significant correlation between them.(2) The coupling coor-dination degree of tourism economy and ecological environment in Guangdong province was increasing year by year , and it could be divided into the following three stages: the unbalanced development stage from 2005 to 2008; the transitional development stage from 2009 to 2011;the coordinated development stage from 2012 to 2014.( 3) From the view point of spatial development , the comprehensive developmental levels of tourism economy of 21 cities in Guangdong province had a significant improvement , while the ecological environment changes of 21 cities presented three trends:continuous rising, fluctuant rising and fluctuant de-clining.The coupling coordination degrees between tourism economy and ecological environment of 21 cites increased in general, and it was affected mainly by hysteretic tourism economy in most cities before 2014, while it was affected mainly by hysteretic eco-logical environment in 2014.%以广东省为例，构建了旅游经济和生态环境综合评价体系，采取综合评价模型和耦合协调度模型对广东省旅游经济综合指数、生态环境综合指数及旅游经济与生态环境的耦合协调关系进行了分析。结果表明：（1）2005～2014年广东省旅游经济综合指数、生态环境综合指数均呈上升的趋势，两者的相关性显著。（2）广东省旅游经济与生态环境的耦合协调度逐年提高，总体可分为3个阶段：2005～2008年为发展不平衡阶段；2009～2011年为转型发展阶段；2012～2014年为协调发展阶段。（3）从空间发展来看，广东省21地市的旅游经济综合发展水平均有显著的提升，而生态环境变化呈现出持续上升、波动上升和波动下降3种趋势。21地市旅游经济与生态环境的耦合协调度总体也呈上升趋势，2014年以前大部分城市主要受旅游经济滞后的影响，而2014年主要受生态环境滞后的影响。
