摘　　要：我国是水资源严重不足的国家之一,自20世纪90年代以来,"引滦入津"、"引黄济青"等引水工程相继完成,"南水北调"还在实施中。以上这些引水工程无疑是解决缺水问题的有效方式。本文提出的"海水西调",与以往引水工程大不相同,其不同之处就是所引之水为海水。海水可说是用之不竭的资源,只要经过淡化就可以成为生活、生产用水。笔者认为,海水西调是可行的,不仅投资效益可观,而且既有利于改善海洋生态,又有利于改善沙化生态环境。China is one of the countries seriously short of water resources.Ever since the Nineties of the Twentieth Century,diversion works such as ＂Divert Ruan He to Tienjin＂、＂Divert Huang He to Jinan and Qingdao＂have been wound up succeedingly,and the ＂South Water Migration Northward＂ Diversion Work is now under construction.These diversion works are no doubt the effective way to solve the problem of water defficiency.The ＂sea-water Migration Westward＂ mentioned in this article is poles apart from the previous diversion works,in that the water diverted is sea-water.Sea-water may be considered inexhaustible and maybe used on daily life and production once desalinized.The author deems it feasible to migrate sea-water westward not only would it gain appreciably in the investment but also it would be beneficial to the improvement of both the marine ecological condition and the sandy ecological environment.
