竖井排水是改良、利用盐碱地的措施之一,利用竖井排水不但可以将地下水降低到任何深度,加速根层脱盐,而且还能迅速淡化地下水的表层,并利用淡化了的地下水进行灌溉。因此,国外已有许多国家采用竖井排水的办法来改良、利用盐碱地,并取得了一些经验。 Shaft drainage is one of the improved and saline-alkali measures. Using shaft drainage can not only reduce the groundwater to any depth, accelerate the root desalination, but also quickly desalinate the groundwater surface and use the desalinated groundwater for irrigation. Therefore, many countries abroad have adopted the method of shaft drainage to improve and utilize saline-alkali land and gained some experience.
