摘　　要：通过对新疆哈密盆地内地下水流运动特征的分析,论述了采用竖井灌排措施前后土壤剖面盐分的不同运移方式及由此可能产生的生态与环境问题。在竖井灌排下,土壤水盐以向下运移为主,土壤处于脱盐状态。这与自然状态下的水盐向上运移是截然相对的;文中还指出了竖井灌排区应加强对地下水资源量的研究,避免地下水的过度超采,保证井灌井排灌区的可持续发展。Based on the analysis of the groundwater flow movement characteristics in Hami Basin,Xinjiang, the paper discussed the different salt transport mode on the soil profile adopted shaft well irrigation and drainage project and resulted ecological and environmental problems. In natural state,salt moves upwards. On the contrary,salt moves downwards in shaft well irrigation area. After long time,the environment will be changed. In fact,groundwater resources should be investigated in shaft well irrigation region. The substantial developed capacity of groundwater can＇t go beyond the guarantee develop capacity. Thus,the activities of human being won＇t bring the side-effect to environment.
