摘要
干旱盆地地下水排泄区以蒸发为主要排泄方式．导致水环境发生恶化，从而引发出一系列的环境问题。本文以吐哈油田南湖水源地建设为例，通过对浅层潜水和深层承压水之间的水力联系的分析，初步探讨了由开采承压水而引起的咸水下移、浅层咸水淡化以及地下水环境得以改善等问题。
The evapotranspiration from surface of arid basin is one from common discharging forms of groundwater. It may be deteriorate the groundwater evironment and cause a series of evironmental problems. Take a situation of the Nanhuwei field in Tuba oil field for example, this paper discusses a development interrelation ofboundary between the confined water and the moving saline water, as well as a desalination of shallow salinewater. This 'paper discusses also the meaning of improving the groundwater evironment in this area.
