摘要:
利用地处川中丘陵区的遂宁水土保持试验站6个坡耕地径流小区1991-2000年的径流观测数据，采用基于Matlab的BP神经网络模型，将5个输入因子（降雨量、降雨历时、降雨强度、植被覆盖率、坡度）、9个输入因子（在5个输入因子基础上增加前期降雨量、前期降雨历时、前期降雨强度及前后降雨间隔时间）、10个输入因子（在9个输入因子基础上增加水土保持措施因子）作为输入因子，冲刷量作为输出因子进行土壤侵蚀建模及预测。结果表明：5个输入因子对输出因子的决定系数（R2）为0.52，模型效率系数（NE）为0.48，预测效果不理想；9个输入因子对输出因子的R2为0.53，NE为0.48，预测效果也不理想；10个输入因子对输出因子的R2为0.57，NE为0.70，预测效果较好，可以达到业务预报水平。
Abstract:
Based on back propagation (BP) neural network, the soil erosion was predicted according to the observational data from 1991 to 2000 of the six runoff plots at Suining Soil and Water Conservation Experiment Station in the central Sichuan Hilly Region. Five factors (rainfall, rainfall duration, rainfall intensity, vegetation cover, slope), nine factors (five factors plus early rainfall, early rainfall duration, pre-rainfall intensity and time interval before and after the rain), and ten factors (nine factors added to water conservation measures) are input respectively, and erosion is output in the model. The results showed as follows: the determination coefficient of 5 factors on soil erosion was 0.52, and the coefficient of efficiency of those was 0.48, which were not satisfactory, while those of 9 factors on soil erosion were 0.53 and 0.48, which were not good either, but those of 10 factors on soil erosion were 0.57 and 0.70, which achieved a satisfactory prediction results and business forecasting.
