摘要:

碳循环模型是模拟陆地生态系统,估计和预测不同尺度碳收支格局和变率的重要手段。但传统碳循环模型应用中存在数据处理量大、运算复杂、互操作性差、难以推广等问题。由开放地理信息联盟(OGC)制定的网络处理服务(WPS)标准为实现碳循环模型的发布、共享、重用与组合,促进碳循环模型的发展和应用提供了一种新的途径。本文遵循OGC WPS标准,以SOA设计了碳循环模型服务平台的整体架构,详细描述了平台模型接口设计、模型算法开发、WPS服务的封装与发布、平台浏览器客户端界面开发等关键环节的实现方法,为用户提供了碳循环相关数据和模型服务的发布、管理、调用、组合、异步交互、状态监控和结果可视化等功能。并以VPM模型服务链为应用实例,演示碳循环模型WPS服务开发、封装、调用和组合的方法,展示了该服务平台的功能。该平台的建立为我国碳循环模型研究的发展提供了技术支撑。

Abstract:

Carbon cycle model is an effective tool in terrestrial ecosystem carbon cycle research, through which people can study the key process mechanism of terrestrial ecosystem carbon cycle and gain more knowledge about its temporal and spatial variation. However, there exist many problems in the application of traditional carbon cycle models, such as vast amounts of data processing, complex calculations, poor interoperability, and difficult to make it more widespread, etc. Using Web Processing Service standard which is established by Open Geospatial Consortium to publish and share carbon cycle models, realize cross-platform invocation, reuse and compose carbon cycle model service, can promote the development and application of carbon cycle models. In this paper, we followed Web Processing Service standard, designed the overall architecture of the online carbon cycle model service platform, and implemented the service platform through a series of processes: service interface designing, models and spatial analysis algorithm developing, Web Processing Service encapsulating and publishing, user interface based on browser client designing and programming, and so on. The online carbon cycle model service platform provided an amount of functions, including carbon cycle data and model service publication, service management, service invocation, service composition, asynchronous interaction between users and background processes, calculation status monitoring, model result visualization, etc. With a Vegetation Photosynthesis Model chain as an application instance, we demonstrated in detail the means to develop, encapsulate, invocate and compose carbon cycle model service found on Web Processing Service standard, meanwhile displayed functions and browser interface of the online carbon cycle model service platform. This platform can be applied to the field of scientific research, decision support, etc., to promote the use of carbon cycle models, thereby make them get rapid development.
