摘要
WOFOST(WOrld FOod STudies)模型是荷兰Wageningen农业大学和世界粮食研究中心(CWFS)共同开发研制,模拟特定土壤和气候条件下一年生作物生长的动态解释性模型。模型着重强调定量土地评价、区域产量预报、风险分析和年际间产量变化及气候变化影响的量化应用。模型以同化作用、呼吸作用、蒸腾作用和干物质分配等作物生理生态过程为模拟基础,主要包括潜在生长条件、水分限制条件和养分限制条件下作物生长的模拟。详细介绍了WOFOST模型的发展、应用范围、理论基础以及使用操作等,便于更多的人快速了解、掌握和使用模型,进一步促进作物模型在我国的发展和业务服务应用水平。
The WOFOST(WOrld FOod STudies) model is developed by Wageningen Agricultural University and the Center for World Food Studies.It is a dynamic explanation model that simulates the annual crop growth with the specific soil and climatic conditions.The model emphasizes the application of land quantitative evaluation,regional yield forecast,risk analysis,the annual yield changes and quantization of the effects of climate change.The simulation of model is based on the crop physiological and ecological process,including assimilation,respiration,transpiration and dry matter distribution.WOFOST model consists of three levels of the crop growth simulation,the potential growth conditions,water-limited and nutrient-limited conditions.This paper introduces the development and application of WOFOST model,its theoretical basis and operation and so on,to facilitate more people to quickly understand,grasp and use the model,and further promote the development of crop models in our country and raise the application level of service.
