摘要: 数字林业领域中部分应用为典型的数据流驱动,但传统的数字林业领域对数据流驱动型应用还缺少有效的支撑环境。在数字林业网格中,设计基于工作流的面向数字林业网格的数据驱动支撑平台,并在此平台上开发若干林业生态工程应用。描述基于工作流的林业应用支撑平台WIFG(workflow-based infrastructure for forestry grid)的设计以及该平台的特点,介绍基于该平台开发的应用——退耕还林规划来说明如何使用该系统进行快速开发。

Abstract: Some applications in digital forestry are data-flow driven. However,no efficient supported environment for data-flow driven applications exists in forestry. In project of digital forestry grid,a workflow-based infrastructure for digital forestry grid that supports data-flow driven application is designed. Some applications are also developed based on this platform. This paper describes the design and features of WIFG (workflow-based infrastructure for forestry grid). Finally,a specific application of planning for converting cropland to forest is introduced to illustrate how to use this system for rapid development.

Key words: workflow, grid, digital forestry
