恢复艾比湖水面抑制干涸湖底尘暴需水量分析

艾比湖是新疆最大的咸水湖,近五十年来,湖区经历了一个由急剧退缩到趋于稳定的变化过程,目前由于国民经济用水大量挤占生态用水,艾比湖湿地区湖泊水面逐年递减,北部湖区常年干涸,裸露湖底盐尘对下风向地区产生危害,本文根据实测湖泊地形,结合遥感调查以及逐月湖面面积的动态特点,对恢复艾比湖水面抑制干涸湖底尘暴所需水量进行分析研究。

Aiby lake is the biggest salt-water lake in xinjiang province.In recent fifties years,Aiby lake area has a change process from sharp decrease to stabilization.Nowadays,owing to a large amount of water for civil economy,Aiby lake area has a gradual decrease,which northern Lakeland is perennial dry and salt dust of bare lake bottom brings some harm to leeward zone.On the basis of surveying lake landform and remote sensing investigation,the paper analyzed the monthly change characteristic of the lake area and studied the require water amount for coming back lake surface and restraining the sandstorm of dry lake bottom.
