摘　　要：本研究以祁连圆柏、柽柳、山杏林地作为研究对象,对其土壤储水量、土壤持水量和耗水量进行综合分析。结果表明:5-8月祁连圆柏林地的土壤平均储水量最高,为38.17 mm,其次为柽柳和山杏林地,分别为32.07 mm、31.63 mm;在相同土壤水吸力作用下,祁连圆柏林地的持水性优于山杏和柽柳林地;生长季山杏的平均耗水量最高,其次为祁连圆柏和柽柳林地。This study took Juniperus przewalskii,Tamarix chinensis and Prunus sibirica were forests as research objects to comprehensively analyze their soil water storage,soil capacity,and water consumption.The results showed that the average soil water storage in the Juniperus przewalskii forest during the growing season was the highest,at 38.17 mm,followed by the Tamarix chinensis and Prunus sibirica were forests,at 32.07 mm and 31.63 mm,respectively;Under the same soil water suction,the water holding capacity of Juniperus przewalskii was better than that of Prunus sibirica were and Tamarix chinensis forests;The average water consumption of Prunus sibirica were during the growing season was the highest,followed by Juniperus przewalskii and Tamarix chinensis forests.
