Abstract:The traditional water resources information management model based on GIS adopts GIS network technology to optimize the allocation of water resources. However, the problem exists of poor information management of polluted water resources caused by earthquake damage, since the model can't produce a comprehensive plan for water resource networks in earthquake-prone areas. An information management model considering pollution of regional water resources from earthquake damage has been designed. The model includes modules for information planning and design of polluted water resources, information monitoring and acquisition of polluted water resources, and management of polluted water resource information. The information planning and design module of polluted water resources was used to optimize the water quality monitoring points of polluted water resource networks after earthquake damage. The monitoring and acquisition module based on the Geodatabase data model was used to monitor and collect polluted water resources after earthquake damage. The information management module included the main and supporting modules, which could realize the comprehensive management of pollution information of regional water resources through different management functions. The experimental results showed that by using the proposed model, the average time of management of regional water resource information after earthquake damage was 1.38 s, and the score of each function of the model in the process of information management was higher than 93.5 points, with high management performance.
