Abstract

Abstract:

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.

Key words: social network, geological hazards, emergency disposal, emergency cooperation relationship, block model, density matrix
