中文摘要：

通过建立环境管理功能状态协调关联模型，并映射生成基于Petri网的功能状态控制过程模型，使得环境信息能够按照流程节点间的结构关系和协调关系及时传递，以在环境管理系统中有效地应用生态预算流程，避免生态预算大跨度、长周期的流程反馈。

英文摘要：

In order to control the eco-budget process effectively in the environmental management system, a functional control process modeling method based on Petri net is developed. A coordination function model with structural and coordination relations among nodes is introduced and its mapping into a Petri net based on functional control process model is established. The process feedbacks with long period and large span can be avoided by employing the method by transferring the design changes to the corresponding designers timely.
