【摘要】：湿地是地球上最重要的生态系统之一，具有重要的生态价值，社会价值和经济价值。由于长期不合理的人为开发，湿地面积日益减少，生态退化，水质污染等一系列问题爆发，因此需要及时地对湿地进行保护和治理。辽河河口湿地是我国北方滨海重要湿地，分布有大面积的赤碱蓬，并为多种珍稀动植物提供生存之所，起着重要的生态作用，但由于长期破坏性的开发导致该地区污染严重。因此，国家开展专项研究和工程对辽河河口湿地进行治理。为方便对该湿地研究，管理，和展示治理成果，需要建立辽河河口湿地地理信息管理系统。本论文介绍了建立辽河河口地理信息管理系统的相关技术，并描述了建立、分析、设计该系统的过程，最后展示了系统运行的部分功能界面。本系统采用Java EE与OpenGeo框架相结合的架构，实现了B/S结构的WebGIS系统。网站采用了当前流行的SSH架构来完成平台搭建，运用MVC模式，为整个系统建立了一个跨平台，可扩展的系统基础平台。为了实现GIS功能，本系统采用了如下架构：使用Openlayers作为客户端实现地图渲染和交互操作；采用GeoServer作为地图服务器，管理图层和发布地图服务；采用PostgreSQL/PostGIS作为基础数据库和空间数据库；并且采用GeoWebCache作为瓦片地图缓存，以降低服务器负担，，提高服务器响应速度。本系统具有良好的用户权限管理机制，能够在确保系统和数据安全的情况下，允许湿地管理员上传新的矢量地图数据，并发新的布图层。这样大大降低系统使用时数据维护和更新的难度。系统提供了一个高度可扩展的平台，方便以后升级和添加新功能。并且由于采用了OpenGeo的体系，可以很好的将架构中各个部分无缝的拼接起来，也可以方便地更换部分技术，使系统更灵活。
[Abstract]:Wetland is one of the most important ecosystems on the earth, which has important ecological value, social value and economic value. As a result of long-term unreasonable artificial development, wetland area is decreasing, ecological degradation, water pollution and a series of problems erupts, so it is necessary to protect and control the wetland in time. Liaohe Estuary Wetland is an important wetland in the northern coastal area of our country. It has a large area of red salvia and provides a living place for a variety of rare animals and plants. It plays an important ecological role. However, because of long-term destructive development, the pollution in this area is serious. Therefore, the country carries out special research and project to Liaohe estuary wetland treatment. In order to facilitate the research, management and management of the wetland, it is necessary to establish the Liaohe Estuary Wetland Geographic Information Management system. This paper introduces the related technology of establishing the Liaohe Estuary Geographic Information Management system, and describes the process of establishing, analyzing and designing the system. At last, it shows some functional interfaces of the system. This system adopts the framework of Java EE and OpenGeo framework, and realizes the WebGIS system of B / S structure. The website adopts the current popular SSH architecture to complete the platform construction, and uses the MVC pattern to establish a cross-platform, extensible system foundation platform for the whole system. In order to realize the function of GIS, this system adopts the following structure: using Openlayers as client to realize map rendering and interactive operation, using GeoServer as map server, managing map layer and publishing map service; PostgreSQL/PostGIS is used as the basic database and spatial database, and GeoWebCache is used as the tile map cache to reduce the server burden and improve the server response speed. The system has a good user authority management mechanism, which can allow the wetland administrator to upload new vector map data and create a new map layer under the condition of ensuring the security of the system and data. This greatly reduces the difficulty of data maintenance and update when the system is in use. The system provides a highly extensible platform for future upgrades and new features. And because of the adoption of the OpenGeo system, it can seamlessly connect all parts of the architecture, and can easily replace part of the technology, making the system more flexible.
