摘　　要：基于田间持水量测定试验数据及土壤理化参数测定试验数据,运用灰色预测理论对田间持水量与土壤理化参数的关联度进行分析,建立以土壤密度、土壤粉粒质量分数、土壤黏粒质量、土壤有机质质量分数为输入变量的GM(0,N)土壤田间持水量预测模型。对所建模型进行残差检验、关联度检验、后验差检验证明所建模型是可行的,实现了少数据、贫信息情况下利用土壤常规理化参数对土壤田间持水量的预测。Based on the test data of field moisture capacity and soil physicochemical parameters,the correlation degree between the soil field moisture capacity and the soil physicochemical parameters is analyzed by using the gray theory and then the GM（0,N）soil field moisture capacity prediction model is established by using the soil density,soil silt content,soil clay content,soil organic matter content as input variables.Finally,through the residual test,the correlation degree test and the posteriori difference test,it is proved that the model is feasible.This model realized using conventional soil physicochemical parameters to forecast soil field moisture capacity with little data and poor information.
