MAO Feng\ MA Qiang\ ZOU Jiying\ DING Yun (Research center for China sustainable development,Peking University,Beijing,100871)  
The authors analyzes the function change of urban in its evolvement and the eco\|environmental problems caused by this change.Based on this analysis and the method of systems ecology founded by Odum H T,the authors discuss the aim and the principle of urban eco\|environment planning under the sustainable development;put forward the general view of urban eco\|environment planning in which the kernel is the adjusting of industry structure,land\|use structure and spatial pattern;construct the dynamic simulating model of eco\|environment planning of Guangzhou city,China which organizes the models of economy,population,the equilibrium of carbon and oxygen,and other models of atmospheric diffusion,rainwater sedimentation,vegetation absorbing to SO\-2,NO x ,TSP;at last simulate the model by means of DYNAMO language and obtain the optimal program of eco\|environmental planning of Guangzhou city.
