对湘北第四纪红土红壤地区四川桤木人工林、台湾桤木人工林土壤水分特征进行了研究。结果表明,四川桤木林枯落物最大持水量达到24.76t/hm2,是台湾桤木林的1.22倍。土壤总孔隙度和非毛管孔隙度大小顺序为:台湾桤木林>四川桤木林>荒地,土壤最大持水量是台湾桤木林最大,为24.55mm。0—45cm层土壤渗透参数大小顺序为:台湾桤木林>四川桤木林>荒地。说明桤木人工林能够改善该地区的土壤结构,使其具有良好的土壤水分特征。

Research on the soil moisture characteristics in Alnus cremastogyne and Alnus formosana forestland with the red soil developed from quaternary red earth in Northern Hu'nan is conducted.Results show that maximum moisture content for the Alnus cremastogyne litter is 24.76 t/hm,which is 1.22 times of that of the Alnus formosana.By both the total capillary porosity and non-capillary porosity,landuses can be ranged in the order of Alnus formosana plantatio...
