Abstract: According to the evaluation method of summer tourism climate suitability,the summer tourism meteorological comfort determined by apparent temperature as the positive contribution index,revising and improving the high impact weather index with negative contribution,such as heavy rainfall,high temperature,gale and thunderstorm,the evaluation model of summer tourism meteorological suitability was established. Based on the observation data of surface meteorological elements from June to August during 2008-2017,the summer tourism meteorological suitability of 84 cities in Guizhou province were analyzed by the model.The results show that:It’s very suitable for summer tourism in Guizhou,especially in central and western regions. However,the best tourist destination changes slightly in different months of summer and key days of midsummer. The meteorological suitability of summer tourism is relatively low in the low altitude areas of the north,east,and south of Guizhou. However,Duyun and Majiang,and so on,which are in Wuling and Miaoling mountains,are suitable for mountain type summer tourism. The summer tourism meteorological suitability in Tongren City ranges from-17 to100. It is a city with poor meteorological conditions of summer tourism in Guizhou. The model can objectively reflect the impact of meteorological conditions on summer tourism.
