新疆艾比湖流域盐尘分析

The Analysis on Salt Dust in the Ebinur Lake Basin of Xinjiang

通过对艾比湖流域的野外考察,以及沿途访问、咨询,分析了艾比湖流域盐尘的成因、加剧的原因、危害以及提出几点治理的办法。结果表明:艾比湖流域盐尘的成因主要是:阿拉山口强劲的大风;丰富的盐尘源;地表干燥、疏松,植被屏障衰退和丧失。近几年主要由于人类不合理的经济活动,使得盐尘源地扩大和地表状况恶劣,造成艾比湖流域盐尘加剧。盐尘的危害也越来越严重,不仅对工农业和人体造成了严重危害,而且已经危及到天山北坡经济带的持续发展,所以治理盐尘刻不容缓。由结果分析要治理艾比湖流域的盐尘,需要减少提供盐尘的源地,改变地表恶劣的状况。

By the field observation to the Ebinur Lake basin, and along the way visit, consultation, the cause of formation, the reason of intensification, hazard of salt dust of the Ebinur Lake basin were analyzed, a few management measures were promoted. The results showed ： the causes of formation of salt dust were strong wind in the Atalaw Pass, rich salt dust source, surface dryness and, loosen, vegetation barriers recession and loss, and mainly due to the unreasonable human economic activities in recent years. Salt dust hazards has become increasingly serious, not only caused serious harm to industry and agriculture, but also jeopardized sustainable development of the economy belt of the northern slope of the Tianshan. So management of salt dust is an urgent thing. Management of salt dust need to reduce the supply of salt dust sources and change the poor surface condition.
