摘  要:
对湘北红壤丘陵区6年生四川桤木人工林的林冠层截留效应、地上部分持水效应以及土壤水文效益进行了研究,结果表明:观测期内林冠截留量占总降水量的22.79%;林地地上部分持水量为4.86 mm,其中林下枯落物持水量最大,为2.48 mm;林地0~45 cm层土壤最大持水量为198.86 mm。四川桤木能够改善红壤的结构,提高土壤蓄水能力。

摘  要:
This paper had a research on the interception effect of canopy,waterholding effect of the woodland above the ground and soil hydrological effect of 6-year-old Alnus cremastogyne Burli plantation in hilly red soil regions of northern Hunan Province.The results showed: during observation period,canopy interception amount accounted for 22.79% of total precipitation amount.And the water-holding capacity of the woodland above the ground was 4.86 mm,the moisture content of litter under forest was largest,reached 2.48 mm.Woodland's largest soil water holding capacity of 0-45cm thickness of layer was 198.86 mm.In addition,A.cremastogyne could improve the red soil structure and increase water storage capacity of red soil.
