【摘要】 为了满足地质环境数据充分高效地服务于中国地质环境管理、综合评价、可视化展示及辅助决策等需求,在分析国内外地质环境信息服务平台应用现状的基础上,总结当前中国地质环境信息服务平台特点及存在的主要问题;提出"分布集成、统一管理、集中服务"的建设模式,进而设计平台逻辑层次,功能体系及内、外接口,并构建中国地质环境信息服务平台。结果表明:中国地质环境信息服务平台逻辑上分为5个层次,自底向上依次为基础设施层、数据层、功能层、服务层和用户层;其功能体系包括分布式地质环境数据集成系统、地质环境信息服务基础支撑系统、地质环境智能感知系统、地质环境综合评价系统和地质环境一张图服务系统;平台五大系统在统一的集成框架下,具有较好的交互性与实用性,可实现分散、多源、异构地质环境数据的整合集成,地质环境变化信息的实时感知,综合信息分类分级评价,地质环境信息多维表征与一张图展示等功能。中国地质环境信息服务平台的构建,对于充分规划、配置、发挥地质环境资源,辅助地质灾害应急决策等具有重要意义。更多还原

【Abstract】 In order to meet the requirement of China geo-environment management,comprehensive evaluation,visualization and decision-making,the applications of geo-environment information service system platform around the world were analyzed,and the characteristic and major issues of China geo-environmental information service platform(CGISP)were summarized;the mode of "distributed integration,uniform management and centralized service"was put forward to build logical layer,function architecture and internal and external interfaces,and then China geo-environmental information service platform was built.The results showed that the five logical layers of CGISP were infrastructure,data,function,service and user from the bottom up;the function system of CGISP included distributed geo-environmental data integration system,geo-environmental information service based support system,geo-environmental intellisense system,geo-environmental comprehensive evaluation system and geo-environmental one-map service system;the above five systems were very interactive and practical under the uniform framework,and implemented the integration of dispersive,multi-source and heteroid geo-environmental data,the real-time sensing of geo-environmental change information,the classification and rating evaluation of summarized information,the multi-dimensional characterization of geo-environmental information and the one-map display.The construction of CGISP played an important role in planning,disposing and exploiting geo-environmental resources,and helping emergency decision-making for geological disaster.更多还原
