The paper studies the basic situations of northwest region using retrieval analysis, actual research and regression analysis. At the same time,with the implementation of the western development strategy and the acceleration of urbanization, as the key of northwestern urban system, the population, economy, society and environment of the middle and small cities change dynamically, the mainly ecological environmental problems which consist of the insufficient of urban green space, water resources short contradictory, laocal environment pollution and urban water and soil loss. In accordance with these problems, it begins the coordination of economy, society and ecological environment from the perspective of environmental planning.After the analysis and research for the status of environmental planning of middle and small cities in eastern Northwest, the paper expounds the problems of urban environmental planning:firstly, the environmental factors change constantly, whether environmental issues or socio-economic conditions all chang in place over time, which are difficult to predict. Secondly, lacking of coordinative outcome between the urban environment and economy. Again, the current environmental planning can't reflect the "planning is a process"directly and effectively, therefore, the formation of environmental planning is lack of response to the dynamic factors in urban development, which results that the environmental function is an "irrational"state, the urban environmental infrastructures are used inefficiently directly or indirectly, and a large number of "amendment" to original planning.On the basis of the research of ecological environmental and planning problems in the northwest region, it presents the notion of urban growth environmental planning. Thinking about the ecology and dynamics throughout the whole process of urban development, and buliding the "growth" index system of environmental planning, which meet the actual situation in the eastern part of Northwest. According to the traditional theory of environmental planning study, "growth" envrionmental planning improves it from the following aspects:the integration of ecological planning and urban environmental planning, predicting the harmony degree of economy, social and ecological environment and developing the dynamic feedback coordination mechanism to planning implementation process. Finally, taking Ankang City, Shaanxi Province for example, through comparative analysis of gray system theory, it found that "growth" environmental planning is the better gudiance to solve the problems in the city of dynamic growth process. The paper aims to explore the operational planning methods, which can guide the balanced development of cities and have both the ecological and dynamic characteristics, to meet the actual situation of the east of northwest region. It has important theoretical and practical significance to the environmental planning concepts and methods of "growth"characteristics, based on the existing urban environmental planning.
