今年10月9日,旅游局召开新闻发布会,通报了近期5A级景区核查情况。河北省秦皇岛市山海关景区被取消5A级资质,云南省丽江市丽江古城景区等6家5A级景区被严重警告。取消河北省秦皇岛市山海关景区5A级资质。原因是:一是存在价格欺诈。二是环境卫生脏乱。三是设施破损普遍。四是服务质量下降严重。导游、医务等岗位人员缺失严重,保安、环卫人员严重不足。5A级景区是公认的旅游景区的最佳品牌,也是旅游产业发展的重要支撑。国家旅游局对5A级景区的管理一直是严格的和动态的。未来将通过摘牌、警告等手段,督促景区始终坚持以游客为本,不断加强管理,改进服务,提高品质。结合材料,运用经济生活有关知识,分析说明国家旅游局做法的合理性。
