使用来自7个长期试验的12个数据集对9个土壤有机模型进行了评估。数据集代表了温带地区内三种不同的土地利用(草地、耕地和林地)和一系列气候条件。同一地点的不同处理(无机肥、有机肥和不同轮作)可以探索不同土地管理的效果。根据测量数据对模型模拟进行了评估，并对模型的性能进行了定性和定量的比较。并不是所有的模型都能模拟所有的数据集；只有四个模型尝试了全部。在所有数据集上，没有一个模型比所有其他模型表现得更好。讨论了每种模型在模拟每个数据集时的性能。对所有数据集的模型的整体性能的比较表明，一组模型(RothC、CADY、DNDC、CENTURY、DAISY和NCSOIL)的模型误差彼此之间没有显著差异。另一组(SOMM、ITE和Verberne)彼此之间没有显著差异，但显示出比第一组模型明显更大的模型错误。详细讨论了模型性能差异的可能原因。(C)1997年爱思唯尔科学公司。
Nine soil organic models were evaluated using twelve datasets from seven long-term experiments. Datasets represented three different land-uses (grassland, arable cropping and woodland) and a range of climatic conditions within the temperate region. Different treatments (inorganic fertilizer, organic manures and different rotations) at the same site allowed the effects of differing land management to be explored. Model simulations were evaluated against the measured data and the performance of the models was compared both qualitatively and quantitatively. Not all models were able to simulate all datasets; only four attempted all. No one model performed better than all others across all datasets. The performance of each model in simulating each dataset is discussed. A comparison of the overall performance of models across all datasets reveals that the model errors of one group of models (RothC, CANDY, DNDC, CENTURY, DAISY and NCSOIL) did not differ significantly from each other. Another group (SOMM, ITE and Verberne) did not differ significantly from each other but showed significantly larger model errors than did models in the first group. Possible reasons for differences in model performance are discussed in detail. (C) 1997 Elsevier Science B.V.
