Research on tourism water resources carrying capacity engineering in Hainan Province

Tourism water resources carrying capacity is an important restriction factor for sustainable development of tourism engineering, also is the key and the difficulty of tourism engineering sustainable development research. This paper constructs the theory and method the tourism of water resources carrying capacity engineering comprehensively and firstly, and makes an empirical study of Hainan Province. The results of the study show that: (1) From 1998 to 2008 the available water resources of Hainan Province have changed from 9.8652 billion tons to 16.764 billion tons, tourism available water supply of Hainan Province has increased from 48.9577 million tons to 206.4160 million tons, the proportion of tourism available water supply to the total available water resources vary from 0.5% in 1998 to 1.23% in 2008; tourism water resources carrying capacity ranges from 17.9169 million in 1998 to 73 million in 2008 in Hainan Province; the figures of tourists climbs from 8.5597 million to 20.60 million, fewer than tourism water resources carrying capacity. (2) The figures of tourism water resources carrying capacity calculated in 2008 are respectively 19.3039 million in Sanya City, 17.4297 million in Wanning City, 11.9911 million in Haikou City, the total is 66.15% of the provincial available water supply, the percentage of other regions is relatively small. The carrying capacity of eastern areas is larger than that in the west. (3) Peak season is the dry season in Hainan Province. (4) The main factors of spatial-temporal differences of tourism water resources carrying capacity are the total water resources and the level of tourism development. Finally, some internal and external suggestions are put forwarded for the improvement of the tourism water resources carrying capacity engineering of Hainan Province.
