Abstract:: With the development of economic construction,people have higher requirements for the living environment.The paper took the Three Gorges reservoir area in Chongqing as an example and analyzed the eco-security issues based on press-states-response model from 20 indicators with the gray relational analysis in the gray system theory since 1997.Gray relational analysis made the results more reasonable because it used the average value between entropy method and AHP as comprehensive weight value.The results showed that:the ecological security of Three Gorges reservoir area in Chongqing was sick both 1997 and 1998,while it was unhealthy state from 1999 to 2007.The situation of the resources environmental pressure was sick in 1997 and was unhealthy from 1998 to 2007.The situation of the resources environmental state was unhealthy in 1997,from 2001 to 2007 and was sick from 1998 to 2000.The situation of human enviroment response was sick from 1997 to 2003 and was unhealthy in 2004 and was sub-healthy from 2005 to 2007.Therefore,ecological security of the Three Gorges reservoir area in Chongqing approches to improve the poor living environment,however,needs to take measures to improve better as soon as possible.
