中文摘要：

基于百度指数分析湖南省5A级景区年度、月度、周度与黄金周的分布特征及其形成机理，研究结果表明：受技术水平、资源丰度、假日制度、重大事件因素的影响，旅游景区网络关注度年际变化大体相似，搜索量逐年递增。大部分景区网络关注度呈现“三峰”状，10月为最高峰，4月和7、8月为次高峰。周度网络关注度周三到达顶峰，周六降至谷底。“五一”和“十一”的网络关注度呈现先升后降特点，其中“五一”期间景区的网络关注度显现出较强的前兆效应，高峰时段为4月29-30日；“十一”期间景区的网络关注度前兆效应减弱，趋于与实际旅游流一致，高峰时段为10月3-4日。湖南省5A级景区应对网络关注度高度重视，紧跟前兆效应。充分运用科学手段进行管理。

The results show that the intranasal variation of net- work attention index is similar and the index has increased year by year.
