中文摘要：

收集2015年网络关注度数据,利用季节性强度指数、旅游需求偏好系数和重心模型,揭示居民对5A级景区旅游需求的时空分布特征,并分析其影响因素。结果发现：居民年内总旅游需求呈山岭形变化,季节波动明显;对单个景区的旅游需求存在单峰型、双峰型、多峰型、W型、U型5个类型;居民对景区旅游需求的年内时间变化主要受到景区资源特性、气候舒适度、节假日、景区景观的季节变化等因素的影响。在空间上,居民的旅游需求主要集中在长白山为中心的东北偏好区、以故宫为中心的华北偏好区、以九寨沟为中心的西部偏好区和以泰山等景区为纽带的环形偏好带4个区域;居民旅游需求在空间上有明显的季节变化,表现为春旅东,夏游北,秋赏西,冬观南;居民对景区旅游需求空间分布主要受到经济发展水平、景区类型、空间距离、气候适宜性、可进入性等因素影响。

英文摘要：

On the collection of the network attention of Beijing residents to 5A class scenic spots,seasonal intensity index,travel demand preference coefficient and gravity center model were used to reveal the spatial and temporal distribution of residents＇ demand for 5A class scenic spots,and the influence factors also were analyzed.Results showed that Beijing residents＇ total travel demand changed like a mountain in a year,and the demand of each spot change like unimodal,bimodal,multimodal,W,and U. Temporally,the demand was influenced by the source characteristics of spots,climate comfort,holidays,and the seasonal change of landscape. Spatially,there were four main preference areas,northeast preference area centered on Changbai Mountain,northern China preference area centered on the Forbidden City,west preference area centered on Jiuzhaigou Valley,and a annular belt through Mount Tai,Mount Hua,etc. Beijing residents＇ travel demand had an obvious seasonal change spatially; residents tended to travel to the East in Spring,the North in Summer,The West in Fall,the South in Winter. The travel demand was mainly influenced by economy,type of scenic spot,distance,climate comfort,accessibility,etc.
