社会网络视角下地质灾害应急处置合作关系

Geohazard emergency response partnerships from a social network perspective

为探究我国地质灾害多部门应急协作关系,从某地质灾害多发省搜集省-市-县3级地质灾害应急管理预案。以参与地质灾害应急职能部门为研究对象,基于社会网络分析方法构建省-市-县3级地质灾害应急合作网络模型。运用中心性与迭代相关收敛法(CONCOR)迭代相关矩阵计算得到主题词块矩阵结构,以此划分各级职能部门间子群的结构层次。通过密度矩阵,研究子群内部之间关系模式,分析各级应急部门在地质灾害应急合作网络中的中心性、网络凝聚力及互动关系。结果表明:应急职能部门在地质灾害应急合作中具有不同的互依性和小团体性,合作模式存在协同不均、信息资源堵塞等问题。整个结构中省-市级应急合作关系相对密切,但县级应急合作网络的整体结构和关系模式相对孤立,部分组织结构间联系程度较低。因此,应进一步加强各职能部门之间的相互协同能力,完善县级政府在应急管理中组织结构建设。

To explore the multi-departmental emergency response cooperation relationship of geological disasters in China,geological disaster emergency management plans at the provincial,municipal,and county levels were obtained from a geological disaster-prone province.Focusing on functional departments involved in geological disaster emergency response,a provincial-municipal-county level geological disaster emergency cooperation network model was proposed based on the social network analysis method.The theme block matrix was calculated by the centrality and iterative correlation convergence method(CONCOR)iterating correlation matrix to divide the structural hierarchy of sub-groups among functional departments.The density matrix was used to investigate the relationship patterns among subgroups and analyze the centrality,cohesiveness,and interaction of emergency departments at all levels in the geological disaster emergency cooperation network.The results showed that emergency departments had different interdependencies and small groups in geological disaster emergency cooperation,and the cooperation pattern had issues such as uneven coordination and blocked information resources.Generally,the relationship between provincial and municipal emergency cooperation was relatively close,but the overall structure and relationship pattern of the county-level emergency cooperation network were relatively isolated with a low level of connection between some organizational structures.Therefore,it is necessary to further strengthen the coordination ability among various functional departments and improve the organizational structure construction of county-level government in emergency management.
