摘　　要：为了解吴起北部典型植被土壤水分特征,本研究选取吴起县长城镇5种典型植被类型(沙棘、山杏沙棘混交林、柠条林、小叶杨林、荒草地)为研究对象,分析了林地土壤贮水亏缺度,结果表明:(1)在0~100 cm土层,各植被类型间的土壤含水量及土壤蓄水量差异显著性(p<0.05),且均表现为沙棘林>山杏沙棘混交林>小叶杨林>柠条林>荒草地。(2)5种植被类型中土壤水分均处于中等变异且沙棘林土壤水分稳定性最高,柠条相对较差。(3)土壤贮水亏缺度表现为荒草地>柠条>山杏沙棘混交林>小叶杨>沙棘。To understand the characteristics of soil moisture with typical vegetation in the northern part of Wuqi County,this study selected five typical vegetation types(Hippophaerhamnoides,mixed forest of Prunussibirica and Hippophaerhamnoides,Caraganakorshinskii forest,Populussimonii forest,and grassland)in Changcheng Town,Wuqi County as the research objects,and analyzed the soil water storage deficit in these forest lands.The results showed(1)In the soil layer from 0 to 100 cm,there were significant differences(p<0.05)in soil moisture content and soil water storage among different vegetation types,with the soil moisture content and soil water storage following the order:Hippophaerhamnoides>Prunussibirica and Hippophaerhamnoides mixed forest>Populusmicrophylla>Caraganakorshinskii>grassland;(2)the soil moisture of the five vegetation types exhibited moderate variation,with the highest stability in the soil moisture of the sea-buckthorn forest and the relatively poorer stability in the Caraganakorshinskii forest;(3)the soil water storage deficit followed the order:weedy grassland>Caraganakorshinskii>mixed forest of Prunussibirica and Hippophaerhamnoides>Populussimonii>Hippophaerhamnoides.
