【摘要】 内涝是一种严重的城市灾害，它给城市的政治和经济生活带来了巨大的破坏。GIS作为一种空间信息处理的强大工具，在城市内涝灾害的分析和预防中起了重要的作用。本文重点讨论了如何利用GIS模型技术构建城市内涝灾害分析模型、评估模型和对策模型。在模型的构建过程中，作者运用了栅格的空间分析、空间统计、网络分析和物资优化配置等GIS功能，最终达到了快速、准确和高效地分析、评估内涝灾害和采取有效的灾害措施的目的。这三个模型将在城市的抗灾减灾工程中取到重要的作用。更多还原

【Abstract】 Waterlog is a serious urban disaster. It has destructive effect to economical and political life in urban. As a powerful tool for handling spatial information, GIS plays an important role in the analysis and the prevention of urban waterlog disaster. The thesis focuses on how to use GIS to build urban waterlog analysis model, evaluation model and countermeasure model. In the process of building model, the author used many GIS functions such as raster spatial analysis; spatial statistics, network analysis and optimum distribution of goods. With these models, we can analyze, evaluate urban waterlog disaster and take effective measures to withstand urban waterlog disaster rapidly, exactly and high-efficiently. These three models will play a key role in the project of urban disaster resistance and reduction.更多还原
