Abstract: Network management becomes more and more difficult because of the diversity of network resources.Aiming at this issue，authors abstract common attributes of network resources，and describe resource from physical layer and logical layer，and then provide a novel resource representation model based on multiple dimensions attributes aggregation.Authors also provide a resource organization method，which organizes resources by establishing physical tree and logical tree.By applying the representation model and organization method mentioned above，we can manage network resources more reasonable and efficient，and then reduce the complexity and cost of network management.

Key words: network resource, multiple dimensions attributes, representation model, organization tree

摘要： 针对网络资源多样性引起的资源组织难度大和管理复杂化问题，通过抽象网络资源通用属性，从物理和逻辑两个层次对资源进行描述，建立了一种基于多维属性集合的新型网络资源描述模型。在此基础上，提出了一种采用组织树结构，物理树和逻辑树相映射的层次化资源组织方法。应用上述表示模型和组织方法，能够实现对网络资源有效的组织管理，降低网络管理复杂性和管理开销。
