Abstract With the fast development of the society and economy, and continual population centralization to the cities, the cities' original ecological balance is changed and destroyed greatly. That debases the quality of human living environment, and challenges the sustainable development of the cities. In order to maintain the district ecological security, strengthen the construction of urban environment, promote the health level of urban dwellers, enhance the sustaining ability of the ecological resource to the city development, realize the balance of the city and the nature in a better level, the function of urban ecological functional district planning has been paid more and more attention in many cities. Beginning with the meaning of urban ecological functional district planning, this paper introduces the methods and the applied theory, and brings forward the viewpoints from some aspects as follows:(1) properly understanding urban ecological system, (2)building the possible ecological resource information bank, (3)seeking the sustainable idealization model of urban ecological system, (4)scientifically making urban ecological functional district planning, (5)making the building guide of the urban ecological functional distrcts, etc. The last conclusions include:urban ecological system is a society-economy-nature multiple ecological system dominated by the behavior of hum an, supported by the natural environment, controlled by the flowing of resource, netted by the social system. Building the ecological resource information bank and single ecological factor drawing layer bank is the base of making ecological district planning objectively and scientifically. In order to build the sustainable idealization model of urban ecological system, we must premise maintaining the sustainable development of the city, research on the best combination of idealization model of natural ecological system and idealization model of social economy development. In order to make the ecological functional district planning scientifically, we must be directed by the environmental problems, guided by the environmental security, and aim at the proper function of environment. In order to ensure the constructive request of urban ecological environment and implementary validity of ecological functional district planning, we must make the rigidity-flexibility com binative building guide of the urban ecological functional distrcts.
