受降雨类型、坡度、植被等多因素的影响,泥沙质量浓度与降雨量之间的关系特别复杂,没有明显的对应关系。通过对工程弃渣坡面径流泥沙质量浓度进行观测,对观测数据采用SPSS11.5统计分析软件进行分析处理,结果表明:降雨量与研究点径流泥沙质量浓度之间的相关性较差。通过分析,只有降雨量与原始弃渣径流泥沙质量浓度有显著的关系,相关系数为0.792;通过t检验,发现降雨量、原始弃渣径流泥沙质量浓度、客土覆盖径流泥沙质量浓度之间都有显著的差异。通过回归分析,根据非标准化系数B,建立的一个回归模型是:Y=10.093+13.134X1-0.386X2;根据标准化回归系数Beta,建立的一个回归模型是:Y=0.803X1-0.052X2。
Influenced by many factors such as rainfall type, slope and vegetation, the relationship between sediment mass concentration and rainfall is particularly complicated and there is no obvious corresponding relationship. By observing the runoff sediment mass concentration on abandoned slope, the observed data were analyzed by SPSS11.5 statistical analysis software. The results showed that the correlation between rainfall and runoff sediment concentration was poor. Through the analysis, only the rainfall has a significant relationship with the sediment mass concentration of the original spoil, the correlation coefficient is 0.792; Through the t test, it is found that the rainfall, the sediment mass concentration of the original spoil, the sediment mass concentration There are significant differences between. According to the regression analysis, a regression model established according to the non-standardized coefficient B is: Y = 10.093 + 13.134X1-0.386X2; and according to the standardized regression coefficient Beta, a regression model established is: Y = 0.803X1-0.052X2.
