摘要
对榆林沙区几种常见的防护树种水分生理特性进行了研究，结果发现：供试的6种树种普遍具有束缚水含量高、束缚水与自由水比值大、水势低、水分亏缺严重等生理指标，不同树种间生理指标具有互为消长的特性。
The study on the moisture physlological characteristics of some pro-tective plants in the dry sand area shows that the 6 plant species tested shaxe thecommon high hound water content,considerable ratio between bound and free watercontent, low water potential and the considerable water saturation deficient. Andthe above indices of different plant species have the characteristics of mutual in-crease or decrease.
