摘　　要：基于配置模型建立一个静脉注射吸毒人群HIV传播的动态分层Agent复杂网络模型,用于模拟HIV在现实共用针具吸毒网络中的传播。在该模型中,共享吸毒网络中的个体分为core层、inner层和outer层,对应吸毒人员中的高危人群、中等危险人群和一般危险人群。网络中层内连接较强,而层间连接较弱,由可调概率矩阵控制。网络中的人群总数可以变化,节点间的连边可以断开和重连,网络具有动态特性。网络中的个体Agent中包括了感染、病程发展以及自愿咨询与检测、国家的免费治疗和免费针具交换等干预政策对个体行为改变、病程和传播的影响机制。仿真实验结果表明,该模型能正确反映不同危险行为层的吸毒人群网络中HIV传播的特点。According to configuration model,a complex Agent dynamic hierarchical network model for the spread of HIV among Injecting Drug Users（IDUs） is developed to simulate HIV transmission in the real needle-sharing network.IDUs on the needle-sharing network can be divided into core layer,inner layer and outer layer,corresponding to highintensity drug users,medium-intensity drug users and general-intensity drug users.The connection within a layer is stronger and the connection between layers is weaker,which is controlled by an adjustable probability matrix.Over time,the number of the total nodes in the network changes,while edges between nodes can be dissolved and reformed.The network has dynamic characteristics.Each individual Agent has infection,course of disease progression and rules to react to HIV prevention interventions,including free syringe exchange programs,voluntary counseling and HIV testing and antiretroviral therapy treatment on individual behavior change,the course of disease and the spread of disease.The simulation results show that the model can correctly reflect the characteristics of HIV transmission among different intensity IDUs networks.
