【 摘 要 】

In many parts of the southwest the ground water supply is exceedingly limited, and the demands for water, already great, are constantly increasing through pumping irrigation, industrial and domestic purposes. When making an inventory of the water resources of a river basin, water consumed by phreatophytes (ground-water vegetation) such as cottonwoods, salt cedar (tamarisk) , willows and salt grass growing in areas of high water-table and along streams becomes of increasing importance as greater land areas are irrigated, especially during periods of drought. Through the process of transpiration these plants discharge and waste large quantities of ground water into the atmosphere.
