动态洪水风险图在佛山城区防洪中的应用

洪水风险图作为一种防洪非工程措施在全国众多城市已经开展推广应用，利用预测降雨信息制作实时、动态的洪水风险图，在目前暴雨频发、多发的城市防洪救灾中更具有现实指导意义。以佛山城区内涝预警系统为例，介绍动态洪水风险图的绘制方法，绘制时需要的基础、实时、预测等关键信息，阐述动态洪水风险图在自动预警、实时预报、历史查询、方案设计、城市防汛决策指导等方面的应用，对佛山城区的防灾减灾具有一定的指导作用。

Technology Research of Data Exchange and Application Service Based on Data Center

The article introduces the research goal and content of techniques of data collection, sharing, and service based on data center, makes the overall technique route, and solves the problem of data influx in heterogeneous systems and databases through integrating and packaging communication technologies. It solves the problem of data sharing between different user nodes in data center, through techniques of JMS, and software-adapter, and data oriented rollback. It achieves the data center application service of different business needs, constructs a provincial water data center model, and forms a solution of data center construction, through the model of mix design mode of the interface and service reuse, event driven model design, micro kernel plug-in. It offers reference for data center construction in future.
