摘　　要：水文信息具有多源、多尺度和异构等特点,为了支持水文信息资源的综合开发应用,需要研究支持动态演化的水文信息抽取与重构机理及实现技术。基于水文信息资源统一组织架构,以描述为核心,以反射机制为支撑,讨论了支持动态演化的水文信息抽取与重构服务的基本原理与方法,并阐述了水文信息抽取与重构服务及需求动态演化的软件实现。Hydrological information possess features of multi-source,multi-scale and heterogeneity.For the sake of integrated exploitation and utilization of hydrological information resources,mechanism and implementation technology for hydrological information extraction and reconstitution based on dynamic evolution need to be studied.On the basis of unified organization framework of hydrological information resources,with description as core and reflection mechanism as support,the author discusses basic theory and methods of hydrological information extraction and reconstruction services based on dynamic evolution,and elaborates information extraction and reconstruction services as well as the software model supporting dynamic evolution.
