摘要
探讨了淤泥质海岸防护林土壤的渗透特性 ,指出同一林分土壤渗透速率差异较大 ,不同样地间土壤渗透速率的差异也十分显著。林地初渗速率大 ,在降雨初期能吸收大量降雨 ,稳渗时渗透速率未必比光板地大。林地土壤渗透过程符合对数曲线 ,相关系数达极显著水平 ;
The soil permeability characteristics of shelter forest in silting coastal area is studied. The results are as follows:Soil permeability rate changed very much even in the same stand and in different plots. The primary permeability rate of forest land was very high, which can absorb a lot of precipitation. Whereas the stable permeability rate might be less than that of bare land. Soil permeability process of forest land followed logarithm curve and the correlation coefficient reached significant level. In addition, the permeability rate was mainly determined by content of organic matter and non capillary porosity in soil.
