| 摘 要： | 新疆是全国水土流失面积大区.以新疆典型小流域-阜康市三工河流域为例,对区域土壤水稳性团聚体分布特征及其影响因素做了初步研究,旨在为小流域土壤侵蚀治理提供重要参考依据.通过对流域内典型梁峁坡地、不同坡度坡地及不同植被覆盖地0-20 cm和20-50 cm剖面层土壤进行采样分析.结果表明,该流域土壤水稳性团聚体含量分布存在以下特征:土壤同-剖面自上而下呈递减趋势;同一坡面随坡位自上而下呈增加趋势;不同坡度则随坡度的增加而减少;不同植被覆盖度土壤水稳性团聚体含量呈现:农用坡耕地<林地<草地<草灌地.

| Abstract: | Xinjiang is a large district suffering from soil and water loss in China,but soil erosion processes in the region have not yet been under stood deeply.Taking San'gong River water shed in Fukang City,Xinjiang Wei Autonomous Region,as an example,a preliminary study for the distribution characteristics of waterstable aggregate content and its influence factors was performed to provide an important basis for soil erosion control.Soils of 0-20 cm and 20-50 cm on a typical hilly slope,slopes of different gradients,and vegetation converage of different degrees were analyzed.Results showed that the dist ribution of soil water stable aggregates in the small watershed had the following characteristics:it had a decreasing tendency from surface down to bottom in the same soil profile;on the same slope,it had a increasing tendency from top to bottom;and on slopes of different gradients,it had a decreasing tendency with slope increasing.In terms of the water stable aggregate content under vegetation coverage of different degrees,landuse was in the descendant order of sloping cropland
