摘　　要：通过对累积入渗量的分析，发现林地土壤入渗性能最佳，荒草地次之，而农耕地最差。方差分析表明，在流域内不同地貌部位之间土壤入渗性能无明显差异，而不同地类之间差异显著，即水土保持林对提高土壤入渗能力有显著作用。多重比较分析说明不同水土保持林地土壤入渗性能也有明显区别；同时发现水土保持林对入渗的空间分布亦有重要影响。The author points out that the infitration property of forest land is better thanthat of grass land and farmland by the analysis of accumulated amount of infiltration,Vari-ances analysis shows that there are no large differences of infiltration property for differentgeograhic positions, but there are large differences of infiltration property for different landuses. There are large differences of the infiltration property of different forests fdr soil andwater conservation by the method of the multiple correlation analysis,The study demo-nstrates that the forest for soil and water conservation exerts a great impact on space distri-bution of infiltration
