Abstract:Climate comfort degree is very important to the development of tourism and it is also a major factor affecting the duration of tourism season. This paper employs a comprehensive climate comfort evaluation model, which is based on temperature humidity index (THI), wind chill index (WCI) and index of clothing (ICL). We select nine famous mountain scenic areas which are typical in China sceneries and analyze climate comfort degree according to the new model. Then the grades of fitness and its temporal distribution are classified. The climate comfort degree of each season and north south variation are analyzed, too. Nine famous mountains are divided into three types based on the distribution of comfort period in a year. The results indicate that: The variation of comprehensive comfort index of Changbai Mountain and Wutai Mountain, which are located in the northern part of China, is like an inverted “V” and the comfortable period is short. The most comfortable period of Changbai Mountain is from June to August and more comfortable tourism period of Wutai Mountain is from June to August. The variation of comprehensive comfort index of Emei Mountain, Huangshan Mountain, Taishan Mountain and Huashan Mountain, which are located in the central part of China, looks like an inverted “U”. And their comfortable tourism period is from June to September. The variation of comprehensive comfort index of Lushan Mountain, Wuyi Mountain and Guilin Landscape, which are located in the southern part of China, looks like an “M” and the comfortable period is the longest. Lushan Mountain’s tourism comfortable period is from May to October， Wuyi Mountain and Guilin Landscape’s tourism comfortable period is from March to April and from October to November.
