Abstract：In recent years due to the marine economy is developing rapidly, the marine economy and marine environment contradict with each other heavily.It is necessary to know the coordinated development of marine environment-economy system in order to get the requirements of sustainable development by scientific evaluation of the system.Using the situation of Guangdong Province as an example, a marine economy-environment evaluation system which involving 2 rule layers, 4 schematic layers and 25 indexes was built based on marine economy's characteristics and marine environment's characteristics.The system is calculated by using the method of combination of principal component analysis and comprehensive index method.The results showed that marine economy - environment system's coordinated development degree of Guangdong Province was increased from 2006 to 2010, but it was decreased in 2009.And then the coordinated development degree was increased in 2010 which showed a good result.In general, the coordinated development degree in unstable state, so some systematic and long-term countermeasures should be taken to improve marine economy-environment system's coordinated development degree of Guangdong Province.
