Simulated winter wheat and maize above-ground dry matter, soil organic matter and soil water, Changwu, China 1983-2015 and future climate scenarios to 2049

The model-generated dataset includes simulated daily dry matter accumulation of above-ground organs (leaves, stems and grains) of winter wheat and maize, soil water content in different soil layers and organic matter stocks in the topsoil and subsoil layers, and final crop dry matter from 1983 to 2004 (wheat) or 2015 (maize). A prediction of the variables under various future climatic scenarios is also included. The SPACSYS model was applied to a historic experimental site on the Loess Plateau in China. Observed crop yields of winter wheat from 1993 to 2004 and maize from 1983 to 2015 were used to validate the model. The validated model was run again under different climate scenarios from 2015 to 2049 to predict daily dry matter accumulation of above-ground organs including leaves, stems and grains, daily soil water content in different layers and soil organic carbon stocks in the topsoil and subsoil layers.

该模型生成的数据集包含了自1983年至2004年（小麦）或2015年（玉米）模拟的地上器官（叶片、茎和籽粒）的每日干物质积累量、不同土层的土壤含水量以及表层和亚表层的有机物储量，以及最终作物的干物质产量。此外，还包括了在不同未来气候情景下对这些变量的预测。SPACSYS模型被应用于中国黄土高原的一个历史实验站点。1993年至2004年的冬小麦和1983年至2015年的玉米的实际产量被用于验证模型。经过验证的模型在不同气候情景下从2015年至2049年再次运行，以预测包括叶片、茎和籽粒在内的地上器官的每日干物质积累量、不同层次的每日土壤含水量以及表层和亚表层的土壤有机碳储量。关于此数据集的详细信息，请查阅https://doi.org/10.5285/03e74f94-88a5-4f09-b9ea-1447dd3e2b85。
