摘要:
于2002年5月份,在陕北黄土区纸坊沟流域选择狼牙刺典型样地,以柠条、撂荒地作为对照.对各地块0～20cm表层土的容重、饱和导水率、水稳性团聚体含量等进行测定.结果分析表明:在0～20cm土层上,狼牙刺对>2mm的水稳性团聚体含量有明显增加作用;对容重、孔隙度影响不明显;年水分动态监测表明,狼牙刺耗水作用强烈,生长期总耗水量可达790mm;耗水深度在2.5m左右
Abstract:
The typical sample plot with Sophora viciifolia was take as research object in the Zhifanggou catchment of the hilly gully Loess Plateau in July 2002.Several soil characteristics such as soil bulk density,permeability and water stable aggregate were measured.Compared with the equivalent characteristics of Caraganar land and fallow land.The result showed that Sophora viciifolia could significantly increase the content of water stable aggregate with the diameter of 2 mm in top soil profile(0~20 cm).No obvious effect on bulk density and porosity was found.The temporal measurement to soil water content in soil profile demonstrated water consumption in the Sophora viciifolia land was great;the whole water consumption is about 790 mm;and the consumed depth could reached to 2.5 m.
