【摘要】 对梭梭秋灌人工林和荒漠林进行了林地土壤水分状况和林木生长状况的研究。结果表明，林地的土壤含水量和蒸散量与冬季降水量相关，林木生长状况与土壤水分状况相关。人工林的土壤水分状况和林木生长状况虽不如荒漠林，属生长一般类型，但水分供需平衡，在仅靠降水抚育的条件下，２．５×３ｍ株行距，１３３３株／ｈａ的密度不会因水分平衡问题出现人工林衰亡的恶果。更多还原

【Abstract】 This paper studied the soil moisture state and forest growing state of Haloxylon atnmodendron autumn irrigated artificial forest and desert forest.The result shows that the soil water content and evaporation amount of forest land has relations with winter rainfall,the forest growing state has relations with soil moisture state.The soil moisture of artificial forest is balance between supply and demand,though it can not be compared with desert forest.更多还原
