| 摘 要： | 在野外调查基础上,应用主分量分析方法得到衡量森林土壤抗蚀性的3个最佳指标:>0.25mm水稳性团聚体、>0.5mm水稳性团聚体和土壤水稳性指数,并以此为变量分析比较不同植被类型及不同土层的土壤抗蚀性变化规律。进一步经DIDCRIM过程判别分析,构建了安吉地区主要植被类型土壤抗蚀性强、较强、差3个等级的判别函数,模型平均误判概率仅为0.0704,具有较高的可信度。 |

| Abstract: | It is found that >0.25mm,>0.5mm water stable aggregates and water stable index can be regarded as the optimum 3 indexes to express soil anti-erodibility of the main forest types in Anji County by means of principal component analysis.Using cluster analysis,changing laws of soil anti-erodibility of main forest types and different soil depth are discussed and the result is satisfactory.With discriminant analysis,we can get 3 discriminant functions concerning good soil anti-erodibility,medium soil anti-erodibility and poor soil anti-erodibility in Anji County.The average mistaken probability is only 0.0704.The model can be used to evaluate soil anti-erodibility in this area. |
| Keywords: | Soil anti-erodibility PCA Evaluation Model Main forest types Anji County Zhejang Province |
