Based on the specific situation of ecological environment of resource-based cities in Heilongjiang Province, this paper puts forward the development goal and key points of sustainable development of ecological environment, and puts forward the guarantee measures of sustainable development of ecological environment of resource-based cities from three levels of government, enterprise and the public. 1 Introduction After data on GDP, energy consumption per unit GDP, employment, and various environmental impacts With the construction of eco-cities and balanced of 9 resource-based cities in Heilongjiang province economic and social development as the core, we will collected over the years were substituted into the input- promote modernization, informationization and oriented dea-ccr model, the calculated annual ecological sustainability in an all-round way. We should build a efficiency values of 9 prefecture-level resource-based healthy and safe environmental maintenance system cities in heilongjiang province were summarized and based on environmental protection to advocate industrial formed as shown in table 1: prosperity and build a sustainable industrial economic system with strong comprehensive competitiveness.
