Evolution Analysis of Eco-environment under the Background of Urbanization in Daqing City

There is an interactive coupling relationship between urbanization and eco-environment, urban planning should consider the development of coordination between urbanization and the ecological environment. In order to provide scientific references to urban development and urban planning, selecting the data of 1995-2009 urbanization and eco-environment in Daqing City,using the factor analysis method and making use of dynamic coupling model to make a quantitative analysis in the trends of urbanization and eco-environment coupled evolution in Daqing City 1995-2009. The results indicate that, the index of urbanization and eco-environment,coordination degree of coupled are in linear growth trend in Daqing City; the speed of urbanization and eco-environment development is not balance, coupling coordination degree shows diversity. The same time when rapid development of urbanization, increasing the input in the construction of the eco-environment,the two coupling relationship will gradually unite,the whole coupling system to, the positive direction.
