中文摘要：

基于百度平台的百度指数获取2011—2015年林芝旅游关注度数据,通过把计算所得的地理集中指数（G）、季节性指数（S）、基尼系数（Gini）,经X12调整过后的HP滤波对网络搜索的时间及空间分布进行探讨。结果表明：林芝旅游关注度持续增加且季节性差异明显增大,呈明显的“双峰双谷”趋势,搜索量较高的地区是北京、广东、西藏、四川等地,呈现“东—西—中”分布。促使林芝旅游关注度提高的动力因素主要有经济发达水平、旅游线路规划、营销战略选择等。

After obtaining the data of 2011-2015 Nyingchi tourist attention based on Baidu indexes, this paper discusses the temporal and spatial distribution characteristics of network search according to the four indicators-geographic concentration index （G）, seasonal index （S） ,the Gini coefficient （Gini）, and HPfilter adjusted by X12. The study shows that： （1）Tourist attention to Nyingchi continued to increase and seasonal differences increased significantly from 2011 to 2015, which presents the double-peak and double-valley form. （2）Nyingchi was searched online the most by tourists from Beijing, Guangdong, Tibet, and Siehuan, and the quantities of searches presents a decreasing pattern of East China-West China-Central China distribution. （3）The main factors for increasing tourist attention to Nyingchi are economic development level, tourist route planning and marketing strategies etc.
