植被和大气之间的相互作用对天气和气候有很大影响。在过去的十年中，人们为改善地表模型（LSM）中植被动态的表示做出了巨大的努力。本研究通过动态作物生长模型 Gecros 扩展了 LSM Noah-MP，该模型能够以天气驱动的方式模拟作物林的发育。这一扩展是在气候预测中模拟双向气候与作物相互作用的先决条件。基于关于能量和水通量的综合五年数据集，以及来自德国西南部两个不同气候地区的土壤水和作物数据，我们采用了作物生长模型 Gecros，将其与 Noah-MP 集成，校准了冬小麦和玉米的耦合模型，并在针对独立测量的多年验证运行中测试了其稳健性。该健全的数据集产生了强大的参数化，在总共 16 个季节的校准和验证运行中均表现良好。由于玉米品种间物候的显着差异，小麦模拟优于玉米模拟。小麦和玉米叶面积指数的模拟动态与标准 Noah-MP 模拟中使用的动态有很大不同。新模型在蒸散量划分为蒸腾量和土壤蒸发量方面产生了显着差异。未来需要在高分辨率作物气候耦合模拟中评估改进的植被动态描述的附加价值。
Interactions between vegetation and atmosphere have a large impact on weather and climate. During the last decade, enormous efforts have been made to improve the representation of vegetation dynamics in land surface models (LSM). The present study extends the LSM Noah-MP by the dynamic crop growth model Gecros that enables simulating the development of crop stands in a weather-driven manner. This extension is a pre-requisite to simulate two-way climate-crop interactions in climate projections. Based on a comprehensive five-year dataset on energy- and water fluxes, and soil water and crop data from two different climate regions of southwest Germany, we adapted the crop growth model Gecros, integrated it with Noah-MP, calibrated the coupled model for winter wheat and maize and tested its robustness in multiple-year validation runs against independent measurements. This sound data set yielded a robust parameterization that performed well both in calibration and in validation runs over in total 16 seasons. Due to pronounced differences in phenology among maize cultivars, wheat simulations were better than maize simulations. The simulated dynamics in leaf area index of wheat and maize differed largely from the one used in standard Noah-MP simulations. The new model yielded pronounced differences in the partitioning of evapotranspiration into transpiration and soil evaporation. The added value of the improved description of vegetation dynamics needs to be evaluated in high-resolution coupled crop-climate simulations in future.
