为从根本上改善西北地区的自然生态环境,科学家大胆设想:将海水引到缺水的大西北--早在20多年前,中国地质大学教授,中国地球物理学会理事陈昌礼先生曾对同事戏言,可以考虑将海水引到缺水的大西北,从根本上改善当地的自然生态环境。但真正静心考虑这个问题,则是近五六年的事。通过大量的实地调查分析,根据伊犁盆地的水汽交换模式,陈昌礼做出了这样的结论:西北地区降水量普遍严重不足的重要原因是西北湿地面积的退缩和消失,由此,西北良好的高山冷凝系统失去了水汽供应源。他认为,西风带,高山山脉冷凝系统和充分的水汽源是西北增雨的三个必要和充分条件,目前西北惟独缺少湿地水汽源,将海水西
In order to fundamentally improve the natural environment in the northwest, scientists boldly envisaged: the seawater will lead to the lack of water in the northwest - as early as 20 years ago, China University of Geosciences professor Chen Changli, director of China Geophysical Society once joke on his colleagues, Water can be considered to lead to the lack of water northwest, fundamentally improve the local natural environment. However, it is almost five or six years since we really meditated on this issue. Through a large number of field investigations and analysis, according to the model of water and gas exchange in the Ili basin, Chen Changli concluded that the main cause of the generally insufficient precipitation in the northwest region is the shrinkage and disappearance of wetland areas in the northwest. As a result, The system lost its water vapor supply. He believes that the westerly belt, alpine range condensation system and sufficient water vapor source is the three necessary and sufficient conditions for northwest rainfall, the current lack of wetlands in northwest water vapor source alone, the sea west
