Abstract: As an important industrial base of petroleum chemical industry in China, for several decades, Daqing City has made a tremendous contribution to China's economy development. But in the meantime as a resources-rich city, inevitably it also has some innate weakness such as industrial structure being single, structure unbalance, infrastructure facilities insufficient, radiation of economy weak and serious destroy of ecological environment, etc. In view of economy development, at present the petroleum mining in Daqing City has come into the middle and later stage. It is the urgent affaires for Daqing City to make the most of the favorable situation brought about by Vigorously Developing the Old Northeast Industrial Base to cultivate substitute industry and realize sustainable and stable development of economy. From the point of view of ecological environment, its supply and demand of ecological track from 1983 to 2001 has been severely unbalanced and the ecology deficit enlarging continuously. It is quite evident that the sustainable development of Daqing City has become an unavoidable serious real problem no matter from economy sense or ecological one. However the sustainable development of Daqing City is extremely complicated, involving very important theoretical issues in respect of regional economics and ecological economics, etc. From the point of view of ecological economics only and on the basis of ecological track model, this paper researches theoretically into the sustainable development of Daqing City.
