本文调查了沙地柏的形态特征、生长发育习性、及其与抗旱固沙有关的生理生态学特性。发现沙地柏匍匐生长,枝叶茂密,根系发达,具有较强的萌根、抽枝繁殖能力,抗风蚀、沙埋。其枝叶内水势低、束缚水与自由水值高,持水力强,蒸腾速率低,抗旱性强,是优良的固沙树种。 This paper investigated the morphological characteristics of Sabina vulgaris, its habit of growth and development, and its ecophysiological characteristics related to drought and sand fixation. It was found that Sabina vulgaris grows prostrately, has dense foliage, developed root system, strong rooting ability, reproductive ability, anti-wind erosion and sand-buried. Its low water potential in the branches and leaves, bound water and free water, high water holding capacity, low transpiration rate, drought resistance, is an excellent sand fixation species.
