摘　　要：自然灾害测报是一门综合的科学,它涉及到的灾害数据采集、信息资源分布、异构等问题制约了行业应用和信息化发展,而网格是新一代高性能计算环境和信息服务的基础设施,能够实现动态跨地域的资源共享和整合工作。自然灾害测报网格(NDPG)基于网格技术,为灾害测报工作服务。本文对自然灾害测报网格的概念、研究内容和框架体系进行了初步探讨,并讨论了NDPG在实现中的几个关键技术问题。Natural disasters prediction is a synthetical science. The problems involved in disastrous data collection, distribution of information resources, and heterogeneous information systems restrain the professional information application and information industrialization. As an innovative high performance computing environment and information services infrastructure, a grid can meet natural disasters prediction by its dynamic, distributed resources sharing and collaboration. Based on grid computing, natu- ral disasters prediction grid （NDPG） serves for disasters prediction. The concept and characters as well as the frame system of NDPG are all introduced and discussed in this paper. The key issues of the realization of NDPG are also discussed in the same time.
