陕北生态退耕区植被群落土壤贮水量与入渗特性

Soil Water Holding Capacities and Infiltration Characteristics of Vegetation Community in Ecological Cropland Conversion Area, Northern of Shaanxi Province

为了研究陕北生态退耕区土壤水文特性,对吴起县县城周边各植被群落土壤贮水与人渗特征进行了研究.结果表明:吸持贮水量和饱和贮水量之间、初渗率和稳渗率之间变化趋势基本相同,而滞留贮水量和饱和贮水量之间的相关性不大;土壤贮水量与入渗率在不同土地利用类型、地貌类型和坡向间变化;草本植被土壤水分人渗性能与坡度、坡向、株均高、容重、非毛管孔隙度、群落密度和海拔因子密切相关.水利论文"~;k8`f7BM`2n
