服务于海岸带环境与生态过程研究的e-Coastal Science平台系统架构设计

从海岸带环境与生态过程研究所面临的问题和需求角度出发,探讨了e-Coastal Science科研协同平台研发的必要性、框架结构、技术路线与支撑技术。即选择海岸带水域环境监测与模拟、入海河流流域空间水文与生态模拟、资源与环境胁迫下的海岸带管理决策三个密切相关的科学问题作为研究单元及平台系统研发的切入点,通过综合应用计算机科学和地球信息科学的基本理论与前沿技术,设计包含IT Infrastructure、GeoScience Platform和Coastal Science Platform的三个宏观层面系统平台,以及硬件平台、数据平台、模型模拟平台、协同与沟通平台和信息发布平台五个技术单元的系统框架,整个系统以Duckling1.2协同工作环境套件、Arc-GIS 9.3地理信息系统为主要支撑技术,并以专业模型工具研发及集成为技术特点。

Framework of the e-Coastal Science Platform for the Coastal Zone Eco-environment Studies

e-Science is about collaborations in areas of scientific research.It will change the way that scientific research is undertaken due to its fundamental goal of minimizing the distance between scientists and information technologies.At the national level,more emphasis are put on researches and constructions of grid and other advanced infrastructure,but scientists individually are more concerned with practical tools and methods that can be integrated on personal computers.The coastal zone is a very special area on the earth where the environmental and ecological processes are very different from that in inland or deep-sea,therefore the coastal zone researches have an especially strong demand for information technology.In past years,great progresses have been made by researchers at home and abroad with regard to information systems and coastal zone management systems.However,the emergence and the fast development of e-Science have not only provided a good opportunity but also pose a very serious challenge for us.It is necessary to develop the e-Science platform in order to meet the increasing needs of distributed and synergetic research activities for the coastal zone environment and ecosystem studies.Therefore,in this paper,the concept of ＇e-Coastal Science＇ was put forward.And the principle,framework,technique route and essential techniques for the e-Coastal Science platform were talked about.In detail,a framework that consist three macro-layers,five technique-units and three research-units was designed for the e-Coastal Science platform.The three macro-layers were IT Infrastructure,GeoScience Platform and Coastal Science Platform respectively.The five technique-units were hardware platform,database platform,simulating platform,synergetic communicating platform and data information release platform respectively.The three research-units were inshore sea area environment monitoring and simulation,hydrology and ecosystem simulation of coastal river basin,and the integrated coastal zone management respectively.To achieve the e-Coastal Science platform,a detailed and feasible technique roadmap was designed mainly based on Duckling 1.2,ArcGIS 9.3 and professional modeling tools.
