全因子试验设计已用于土壤侵蚀研究，但由于时间、成本和劳动密集型，有时由于需要考虑的因素数量和水平的增加而无法进行。田口设计是一种简单、经济和有效的统计工具，它只使用总可能因子组合的一部分来获得研究结果。使用田口设计的土壤侵蚀研究很少，也没有与全因子设计进行比较。本文采用全因子设计，对5种坡长（0.4、0.8、1.2、1.6和2 m）、5种坡度（18%、27%、36%、48%和58%）和5种降雨强度（48、62.4、102、149和170 mm h−1）进行了一系列模拟降雨实验。根据理论田口设计从完整数据集中提取数据，验证了田口设计在沟间侵蚀实验中的适用性。比较了各试验平均准稳态侵蚀径流量的统计参数、产生最大侵蚀径流量的最佳条件、全因子设计和田口设计中各因子的主效应和贡献率。两种设计产生了几乎相同的结果。利用田口设计的实验数据，可以准确地预测田口设计中排除的条件下的侵蚀和径流速率。两种设计的实验数据分析结果均表明，田口设计可应用于沟间侵蚀研究，并可取代全因子设计。这将节省时间、人力和成本，因为通常会减少要进行的测试次数。进一步的工作应该测试田口设计在更广泛条件下的适用性。
Full-factorial experimental designs have been used in soil erosion studies, but are time, cost and labor intensive, and sometimes they are impossible to conduct due to the increasing number of factors and their levels to consider. The Taguchi design is a simple, economical and efficient statistical tool that only uses a portion of the total possible factorial combinations to obtain the results of a study. Soil erosion studies that use the Taguchi design are scarce and no comparisons with full-factorial designs have been made. In this paper, a series of simulated rainfall experiments using a full-factorial design of five slope lengths (0.4, 0.8, 1.2, 1.6, and 2 m), five slope gradients (18%, 27%, 36%, 48%, and 58%), and five rainfall intensities (48, 62.4, 102, 149, and 170 mm h−1) were conducted. Validation of the applicability of a Taguchi design to interrill erosion experiments was achieved by extracting data from the full dataset according to a theoretical Taguchi design. The statistical parameters for the mean quasi-steady state erosion and runoff rates of each test, the optimum conditions for producing maximum erosion and runoff, and the main effect and percentage contribution of each factor obtained from the full-factorial and Taguchi designs were compared. Both designs generated almost identical results. Using the experimental data from the Taguchi design, it was possible to accurately predict the erosion and runoff rates under the conditions that had been excluded from the Taguchi design. All of the results obtained from analyzing the experimental data for both designs indicated that the Taguchi design could be applied to interrill erosion studies and could replace full-factorial designs. This would save time, labor and costs by generally reducing the number of tests to be conducted. Further work should test the applicability of the Taguchi design to a wider range of conditions.
