涉水地质灾害多源数据管理与应用探讨

为了解决由涉水地质灾害多源性与差异性导致的数据在计算机系统中的存储及查询困难问题，在分析各种数据特性的基础上，对当今先进的P2P索引网络技术整合、查询数据资源的功能进行了分析。分析表明，P2P网络索引技术可有效利用网络的边缘资源，并依据组策略，利用索引节点算法完成多源海量数据的网络查询请求，为分布式的地质灾害多源数据管理提供一种解决方案。将P2P技术应用到唐家山堰塞湖的应急处置中，获得了较好的效果。

Discussion on multi -source data management and application of water - related geological disaster

In order to solve the difficulties of data storage and inquiry in computer resulting from multi-source and difference of geological disaster involving water,on the basis of analysis on the features of various data,the functions of data integration and inquiry by advanced P2P network index technology are analyzed.The analysis shows P2P network index technology can effectively use marginal resources of network and fulfill network inquiry of multi-source data by index node algorithm based on group policy,which provides a solving scheme for distributed multi-source data management of geological disaster.P2P technology is applied in treatment of Tangjiashan dammed lake and good effect is obtained.
