基于PSR模型的滨海旅游地生态安全评价——以日照市为例

Study on Ecological Security Evaluation of Coastal Tourist Based On PSR Model—— Evidence from Rizhao City

文章通过构建PSR生态安全评价模型，建立了以日照市为例的滨海旅游地生态安全评价指标体系。运用熵值法确定指标权重以及综合指数法计算研究区域的生态安全总值，对日照市生态安全状况进行动态分析，结果表明：2010-2014年，研究区域的生态安全经历了先上升后下降再上升的年际动态变化，但生态环境总体朝着良性发展。具体表现为：研究区域压力升高，旅游环境资源面临较大压力；状态方面呈现出波动变化，目前处于平稳状态；响应方面呈回升趋势，科技水平低下和生态保护措施不到位是影响其提升的主要因素。

By constructing PSR ecological security evaluation model, this paper sets up an evaluation index system of ecological security of coastal tourism destinations in Rizhao. By using the entropy method to determine the index weights and comprehensive index method to calculate thetotal ecological securityof the study area. It is concluded that the ecological security of the study area has experienced the inter annual dynamic change of rise, fall, rise in 2010 to 2014. However, theoverall ecological environment towards benign development. The specific performances of Rizhao coastal tourism destination are pressure increased, tourism resources are facing great pressure; state showing fluctuations, and it under stable states now; response showed increasing trend, the main factors of the decline are ecological protection is not perfect and the low level of technology.
