【摘要】：随着全球生态环境的恶化,生态安全受到人们的普遍关注,生态安全已经成为继国家安全、经济安全之后另一个国家重要的发展战略。旅游行业的特殊性要求其发展依托于良好的生态环境,在生态安全得到广泛应用的背景下,旅游城市的生态安全也逐渐得到了旅游相关方面的学者和专家的关注。为了改善和维持旅游城市的可持续发展,学者开始致力于旅游城市生态安全的评价,以期寻求旅游城市生态安全问题的症结,并提出建设性的建议。本文以旅游城市生态安全为研究对象,在对已有文献研读的基础上,尝试以生态评价典型的DPSIR模型为支撑构建旅游城市生态安全评价指标。采用理论分析法、层次分析法和专家访谈法等多种方法相结合的研究手段,建立旅游城市生态安全评价体系,采用熵权法和AHM属性层次模型确定指标的组合权重,对旅游城市生态安全进行评价。为验证模型的有效性和科学性,论文以著名旅游城市大连为例,对大连的城市生态安全进行评价。评价结果显示大连在2003年至2012年十年间城市旅游生态环境发生了很大的变化,DPSIR模型中的驱动力指数、压力指数、状态指数、影响指数和响应指数均发生了不同程度的演化,通过对各指数演化趋势的分析,识别出大连城市旅游发展的薄弱环节和亟待解决的旅游城市生态安全问题。案例研究的结果表明,本文建立的旅游城市生态安全评价指标体系和方法比较科学,可以对旅游城市生态安全进行有效的评价,从而促进旅游地生态、社会和经济的协调发展。
[Abstract]:With the deterioration of the global ecological environment, ecological security has received widespread concern, and ecological security has become a national security. After economic security, another country's important development strategy. The particularity of tourism industry requires its development to rely on a good ecological environment, in the context of ecological security has been widely used. In order to improve and maintain the sustainable development of tourism cities, scholars begin to devote themselves to the evaluation of ecological security of tourism cities. In order to explore the crux of the ecological security of tourist cities, and put forward constructive suggestions. This paper takes the ecological security of tourism city as the research object, based on the study of the existing literature, attempts to construct the ecological security evaluation index of the tourism city by using the typical DPSIR model of ecological evaluation as the support, and adopts the theoretical analysis method. The evaluation system of tourism city ecological security is established by the combination of analytic hierarchy process (AHP) and expert interview, and the combined weights of indexes are determined by entropy weight method and AHM attribute hierarchy model to evaluate the ecological security of tourist cities. In order to verify the validity and scientific nature of the model, this paper takes Dalian, a famous tourist city, as an example. The evaluation results show that the urban tourism ecological environment in Dalian has changed greatly during the ten years from 2003 to 2012. The driving force index, pressure index and state index in DPSIR model have been changed greatly. Both the influence index and the response index have evolved to different degrees, and through the analysis of the evolution trend of each index, The weak links of tourism development in Dalian city and the ecological security problems of tourism city are identified. The result of the case study shows that the evaluation index system and method of ecological security of tourism city established in this paper are relatively scientific. The ecological security of tourist cities can be evaluated effectively, and the harmonious development of ecology, society and economy can be promoted.
