基于WebGIS的水环境模拟关键技术研究

摘要

近年来随着水环境模拟领域的发展出现了较多水环境数学模型,目前日益成熟的WebGIS技术是使模型使用变得简单化和直观化的一大途径.是在通过Flex和ArcGIS Server搭建WebGIS系统平台的基础上,利用PHP进行WebGIS和水环境模拟模型的数据交互,实现系统平台和数值模型的松散耦合.用户在浏览器端进行模型输入条件的设置,模型在远程服务器端进行运行计算,反馈的模拟结果通过RIA在WebGIS中进行多元化动态展示.该方法对一般模型具有适用性,可降低模型使用门槛,提高模拟结果展示和分析能力.%Recently, many models appear along with the development of water environment modeling, and the robusttechnique of WebGISis a recommended way to make the usage of models easier and more visualized.On the foundation of establishing WebGIS platform using Flex and ArcGIS Server, PHP is taken advantage of in the process of data interaction between WebGIS and water environment simulation model, where the loose coupling is realized.Users set up the model input conditions on the browser-side, afterwards the model begins its calculating on the remote server-side, and the results can be displayed dynamically through RIA.This method is suitable for general models, which makes them easier to getting startedwithand improves the ability of demonstrating and analyzing the simulation results.
