Soil-plant-atmosphere interactions at the regional scale

大气-地表耦合模式是在区域尺度上预测全球气候变化影响的重要工具。然而，区域模拟的不确定性很大。这至少部分是由于对土壤-植物-大气相互作用描述的不足。在这个项目中，我们将把作物模型与陆地表面模型结合起来，测试最终模型系统的能力，并回答一个问题，在这个问题中，必须对详细的运输和生长过程进行建模，以产生可靠的区域气候条件预测及其对农业、景观水状况和景观结构的影响。

Coupled atmosphere-land surface models are important tools for predicting the impact of global climate change on a regional scale. The uncertainty of regional simulations is large, however. This is, at least partly, due to deficiencies in the description of soil-plant-atmosphere interactions. In this project, we will integrate crop models with a land surface model, test the capability of the resulting model system and answer the question in which detail transport and growth processes have to be modelled to produce reliable projections of regional climatic conditions and their impact on agriculture, landscape water regime and landscape structure.
