艾比湖流域风沙天气与艾比湖干缩之间的关系初探

本在探讨艾比湖风沙天气形成机制的基础上，对艾比湖流域风沙天气与艾比湖干缩之间的关系作了初步研究，指出由于艾比湖的干缩而导致的风沙天气主要是浮尘天气，浮尘来源主要是干涸湖床所形成的盐尘，但也有因大规模开荒而形成的沙土尘。引起艾比湖风沙天气变化的原因是多方面的，但人为因素是第一位的，其中以河流上游大量截流引水和大规模开荒为主要原因。风沙天气对艾比湖流域(尤其是精河县)的人类生产生活活动的危害是十分严重的，但与其它因素导致的风沙天气相比，因湖泊干缩而产生的风沙天气对精河县的危害相对而言居于次要地位。

Preliminary Discussion on the Relationship Between Sand-Dust Weather and The Shrink of Erbin Lake

Based on analysis of the causes of sand-dust weather in Erbin Lake Basin in Xinjiang this paper discusses the relationship between sand-dust weather and the shrink of Erbin Lake.The shrink of Erbin Lake mainly causes suspended-dust weather.The suspended dust comes from not only the salt-dust in dried Erbin Lake bed,but also cultivated land.The causes arising changes of sand-dust weather in Erbin Basin are complex.However,the main cause is incorrect human activities,especially large-scale reclaiming and agricutural irrigation.The impacts of sand-dust weather on human living in Erbin Lake basin are very severe,especially in JingHe County.But compared with the impacts mentioned above,the impacts of sand and dust weather on Erbin Lake basin (especially in JingHe County) are not severe.
