基于Web GIS的中国外来入侵物种地理分布信息系统的设计与开发

Development of Web GIS-based Geographic Distribution System on Invasive Alien Species in China

以中国外来入侵物种及其安全性考察取得的原始调查数据为基础,针对外来入侵物种调查协作中数据管理与共享利用等方面的需求,完成了系统技术架构、数据库及系统功能设计,开发实现了入侵生物分布调查数据查询、属性数据浏览、专题图生成、地图操作等功能。本文分析了入侵生物的主要数据来源、描述了基于物种编目的数据模型、介绍了基于SOA架构的Web GIS技术方案及系统的主要功能,并对系统的优势、不足及今后拓展应用的方向进行讨论。

Using the data collected from the field survey on the invasive alien species（IAS）in China,a Web GISbased geographic distribution system was developed for information management and sharing.The design on the functions,database,and framework for the system was completed.It included the data query,browsing,thematic mapping,and map operation.The origins of the cited data and the established models from the IAS catalog,the system framework and detailed functions,as well as the advantages,shortcomings,and potential applications of this geographic distribution system are presented.
