艾比湖1961—2001年的演化特点及机制分析

Evolvement Characteristics and Mechanism of the Ebinur Lake from 1961 to 2001

利用40 a的实测数据分析艾比湖的演化特点及机制。研究表明:艾比湖气候恶化,干旱少雨,蒸发量大,特别是与特殊的地形地貌相匹配,风多风大,沙尘暴和浮尘活动频繁。入湖水量逐年减少,湖面蒸发量大,湖泊面积处于萎缩阶段。影响湖泊演化的因子主要是气候变化及人类活动。

The evolvement characteristics and mechanism of the Ebinur Lake were studied based on observation data from 1961 to 2001.Results showed that the climate over Ebinur Lake is worsening, dry and little rain, large evaporation, and especially the frequent gales , sandstorm ,and flowing dust, which quite match to the special terrain and geography there.The water volume flowing into Ebinur Lake is reducing year by year, and the evaporation is large,As a result, the lake area is smaller and smaller, climate change and human activity should be primarily resposible for the evolvement.
