摘　　要：以浙江省为案例地,构建了基于PSR-EES模型的旅游生态安全评价指标体系,运用改进的TOPSIS法对其2000~2012年旅游生态安全进行了动态评估,并使用生态安全等级动态度模型、马尔可夫链模型、灰色关联度模型对其时空格局和障碍因子进行了分析。结果表明:1 2000~2012年,浙江省旅游生态安全指数由0.399增加至0.628,安全等级从敏感等级上升至一般安全等级;2浙江省旅游生态安全风险等级和敏感等级的城市数量减少,而临界安全和一般安全等级的城市数量增加,且旅游生态安全等级存在跳跃式转移;3浙江省旅游生态安全主要障碍因子为游客数量增长率、旅游收入增长率、环保投入占GDP比重和森林覆盖率。Scientifical assessment on the ecological security of tourist destinations is important for achieving the sustainable development of tourism. Based on the principles of systematicness, hierarchy, maneuverability and the procurability of research data, and the actual situation of tourism economy and ecological environment in Zhejiang Province, this article combines the Pressure-State-Response(P-S-R) model and the Economic-Environment-Social(EES) model to construct a tourism destination ecological security evaluation index system.The mean-square-error decision method was used to calculate the weight of the evaluation index. We used improved TOPSIS to conduct a dynamic evaluation index of the tourism destination ecological security in Zhejiang Province form 2000 to 2012. The spatio-temporal pattern and its obstacle factors were studied using ArcGIS software, dynamic model of ecological security level, the Markov chain model, and the gray relative level model. The results showed the following: 1) from 2000 to 2012, the tourism destination ecological security comprehensive index increased from 0.399 to 0.626, the security level raised from the sensitive grade to the general safety grade. In this period, there were a risk grade in 2000-2002 and 2004-2005; a sensitive grade in2006; a critical safety grade in 2003, 2007 and 2010; and a general safety grade in the other years. The tourism destination ecological security in Zhejiang Province still has a big space to promote. 2) In Zhejiang Province,the number of cities with risk grade and sensitive grade for ecological security decreased while that with a critical safety grade and general safety grade increased. Furthermore, the increase speed of the number of cities with the relatively high security grade is faster than the decrease speed of the number of cities with the relatively low security grade. There exists a leaping development among the transfer process of different ecological security grades. 3) The main factors affecting ecological security are the growth rate
