Climate Suitability Index for City Tourism in China
Climate is the main factor in tourism development This article used the human climate suitability index to evaluate the climate suitability of cities, including the THI(temperature humidity index)、K( index of wind effect ) and ICL (index of clothing). Firstly, the article calculated the value and the bias value of the human climate suitability of 44 cities in China, and analyzed the suitable duration and the change of the index value and the bias value of the human climate suitability. Then it was found that there were 19 cities with five suitable months and few cities with too long or too short suitable duration. According to the climate suitability duration and the distribution of suitability months, the article classified the climate suitability duration into three classes and two types. Secondly, the comfortable seasons are spring and autumn, the comfortable months are April and October for most places except the tropical ones. In summer,the climate tends to be heated bias,particularly in Haikou,where the bias reaches the maximum, and the comfortable places are Lijiang,Kunming and so on. In winter,the climate tends to be cold bias, particularly in Harbin,where the bias value reaches the maximum,but in the tropical or subtropical places people feel comfortable. Lastly,to evaluate the overall climate condition of the cities,the article classified 44 cities into five clusters by means of Kohonen neural network self-organization in Matlab. The results show the fist class, with the highest climate suitability bias, is comfortable in summer and suitable for tourism. People should prevent coldness in the other seasons,particularly in winter,but the special cold in the north can attract people to travel. The second class is comfortable in winter, most of which are coastal cities and suitable to travel. The third class, with the average bias level, has the comfortable seasons of summer and winter, The forth class, with the lowest bias level, is cool in summer and warm in winter, and the overall climate is comfortable, so the cities included have the climate advantage to develop tourism. The fifth class,where is hot in summer and cold in winter,must make full use of the comfortable spring and autumn and develop the particular tourism resource in order to improve the regional tourism competition.
