There is an interaction and mutual influence between economic development and environmental protection in the Areas of Dongting Lake. However, in different regions, the ways and extent of effect are not in the same .Through the research of succession path between economic growth and environmental pollution in the whole Dongting Lake area, Yueyang, Changde, and Yiyang City, the results show that industrial waste gas and industrial dust in the whole Dongting Lake area has crossed the inflection point of EKC while industrial waste water is still in the right side of the ＂U＂ type curves. The features of ＂Inverted U＂ curve of industrial waste gas are more obvious in Yueyang, Changde and Yiyang City. And the turning point occurred during the period of ＂llth five-year＂. It reflects that the relationship between economy and environment has been in succession from ＂positive correlation＂ to ＂negative correlation＂ in the Areas of Dongting Lake. By LMDI analysis it is concluded that economic scale and industrial structure are the pull factors influencing the pollution emission in the Areas of Dongting Lake, while the pollutant emissions intensity factors play an important degree of inhibition.
