Abstract:In order to deeply analyze the influencing factors and forming process of urban atmospheric environmental bearing capacity （AEBC） and to evaluate its bearing capacity level， a function Petri net（FPN） model of urban AEBC was proposed. The concept of function was introduced in the traditional Petri net， and the operation rules and function expressions of transition were given. Combining the urban system with the functional Petri net， the evaluation model of urban atmospheric environmental bearing capacity was established， which consisted of four subsystems ， namely social production ， economic energy consumption ， atmospheric environmental protection and atmospheric environmental carrying capacity， and then the operation steps of the model were given. Finally， the index of AEBC was adopted to evaluate and analyze the urban AEBC. The case analysis showed that the model could directly reflect the formation and changing process of urban AEBC ， the influence degree of the main factors， and the level of bearing capacity. The evaluation of atmospheric environmental bearing capacity through the function Petri net could fit the reality and be convenient for guidance.
