Abstract:
Water environment is the basic environment for the social and economic development and is a complex system for human survival and development. Moreover, it is the most vulnerable to the disturbance and destruction of human activities. In recent years, the rapid development of industrialization and urbanization of Hainan Province has resulted in different degrees of pollution in the water environment. At the same time, with the development of Hainan as an International Tourism Island, the demand for fresh water has increased dramatically due to the increasing of visitors, which will lead to significant impacts on the water environmental carrying capacity of Hainan Province. In this paper, the water environmental carrying capacity of Hainan Province was analyzed using the combined method of Analytic Hierarchy Process (AHP) and “mode and sum”. The results showed that the water environmental carrying capacity of Hainan Province has increased gradually from 2005 to 2010, but it was in a weak level and the state of water environment was very fragile. Through the analysis of the current situation of water environment of Hainan Province, the measures to maintain and enhance the water environmental carrying capacity of Hainan Province were proposed.
