用于田间作物—水分关系研究的ThuSPAC模型

The ThuSPAC Model and Crop-Water Relations

田间作物水分关系是土壤植物大气连续体 (SoilPlantAtmosphereContinuum ,简称SPAC)理论的重要研究内容。本研究介绍的ThuSPAC(TsinghuaUniversitySPAC)模型 ,包含土壤水热运移 (Soil)模型、冠层 (Canopy)模型、土壤 -植物 -大气连续体 (SPAC)模型、冬小麦生长模拟 (Wheat)模型、冬小麦生长与SPAC水热运移耦合的WheatSPAC模型 5个独立的模型。利用ThuSPAC模型 ,可以根据土壤条件、冬小麦品种参数、气象条件及灌溉条件等 ,动态模拟土壤、冠层中水分温度的分布规律、冬小麦生长过程及最终产量。模型的开发语言为VisualBasic ,界面友好 ,在相关领域的研究中具有广泛的应用前景。

The field crop-water relations are important content of the SPAC (Soil-Plant-Atmosphere Continuum) theory. The ThuSPAC (Tsinghua University SPAC) Model consists of five models,which are the Soil Model, the Canopy Model, the SPAC Model, the Wheat Model and the Wheat SPAC Model,and each one can run separately. By using ThuSPAC Model, the dynamic moisture and temperature in soil and the winter wheat growth process can be gained having the soil parameters,wheat parameters,weather and irrigation data. The ThuSPAC Model, written by Visual Basic, with user-friend interface, can be widely used in the related researches.
