A computational framework for spatially explicit agroecosystem modeling: Application to regional simulation

摘要

Site-based agroecosystem model has been applied at regional and state level to enable comprehensive analyses of environmental sustainability of food and biofuel production. However, spatially explicit ecosystem simulations over large landscape present computational challenges. This paper presents a framework to support spatially explicit agroecosystem modeling and data analysis over large landscape, which includes four major phases of agroecosystem simulation: simulation data preparation, site-based simulation on high performance computers, data management and data analysis. Then, a case study on a regional intensive modeling area (RIMA) was presented as an application to demonstrate the system implementation and capability.
