　　摘  要：為解決水利空間數據共享困難的問題，江蘇省基于開放地理信息標準，采用去中心化技術路線，構建水利一張圖。利用OGC（開放地理空間信息聯盟）提供空間數據交換和服務互操作協議，具體接口可以在業務領域定制化實現，提出以OWS（OGC網絡服務）融合異構空間數據，實現地圖局部更新和統一風格展示；通過URI定位屬性并與Solr搜索引擎結合，擴展WFS實現基于語義的空間信息查詢；基于服務鏈和工作流整合水利空間功能；結合LDAP協議實現CSW服務，構建跨部門、級別、業務的細粒度空間信息目錄；通過服務負載均衡，實現云端GIS等方案。從技術上實現水利一張圖平臺框架，可滿足水利空間信息公共服務的功能、性能需求，并為基于水利一張圖整合全省水利信息資源，提供理論參考和技術借鑒。

　　Abstract：In order to solve the difficulties of water conservancy spatial data sharing, Jiangsu Province, based on the open geographic information standard, adopts the decentralized technology route and builds water conservancy one map. Using OGC (Open GIS Consortium) to provide spatial data exchange and service interoperability protocol, of which the specific interface can be customized in business field. OWS (OGC Network Service) is proposed to integrate heterogeneous spatial data for realizing map partial update and unified style display. By combining URI positioning properties with Solr search engine to expand WFS, it realizes semantics spatial information query based on semantics. Water conservancy spatial functions are integrated based on service chain and workflow. Realizing CSW service based on LDAP protocol, fine-grained spatial information directory is built cross department, level and business. Through service load balancing, cloud GIS and other solutions are realized. Platform frame of water conservancy one map, which is realized by technology, can meet the function and performance demand of public service of water conservancy spatial information, and provide theoretical and technical reference for integrating water conservancy information resources of the whole province based on water conservancy one map.
