Abstract: By taking Guangdong Province as a case, this paper applied the methods of mathematical statistics and GIS spatial analysis to analyze and discuss the spatial structure and evolution process of hot spring resorts. The results show that the spatial distribution of hot spring resorts is a cluster distribution situation and high concentration degree. The utmost disproportion in dimensional distribution is existed and the distribution density of hot spring resorts is higher in the Pearl River Delta and mountains of northern Guangdong. The evolution and development of hot spring resorts include 4 stages: indoor hot spring，outdoor hot spring，theme hot spring and vacation hot spring，which is mainly affected by the resource endowment, the tourist source market, the traffic condition and the changing consumptions of tourism market.
