为探讨凝结水对臭柏的作用,采用人造凝结面法、离体枝条法和盆栽封袋法,分析了在干旱季节臭柏冠层凝结水的形成和作用.结果表明,臭柏冠层凝结能力从大到小依次为100、50、150和5cm,其中100cm处凝结时间最长,能够代表冠层拦截凝结水的能力,该处凝结水的发生分为3个阶段,即发生前期(14:00～22:00)、发生时段(22:00至次日8:00)和蒸发时段(8:00～14:00).人造凝结面和离体枝条凝结水拦截量都与凝结持续时间呈线性正相关.高密度栽植的臭柏冠层可以不间断地向土壤方向输入水汽.通过盆栽封袋法证明凝结水对臭柏作用显著.

For researching of the effect of dew on Sabina vulgaris,using methods of artificial condensation surface,detached shoots and bag closure of petted culture to determine dew formation and absorption by canopy of Sabina vulgaris on arid season.The results indicated that the capacity of dew formation was the biggest on 100cm of Sabina vulgaris canopy,which can represent capacity of the whole canopy.There were three periods that were the previous period of dew formation(14:00～22:0),the period of dew formation(22:00～8:00),the evapemted period of dew(8:00～14:00),respectively.The intercepting quantity of dew by artificial condensation surface and detached shoots were linear positive correlation with dew duration.Sabina vulgaris canopy of high density could uninterrupted provide water vapor to soil direction,at the sanle time,effect of dew wag significant to Sabina vulgaris.
