基于遥感技术的艾比湖储水量和需水量研究

艾比湖湖水很浅,湖底平坦,沉积着巨厚的细沙和淤泥。依据自身特征及其他因素,针对艾比湖水量的收支情况,建立艾比湖的储水量和需水量的数学模型。其中艾比湖湖面面积数据是重要参数之一,利用遥感技术,采用资源卫星影像,结合Modis数据,解译提取获得。通过艾比湖储水量和需水量数据可以进一步预测艾比湖湖面面积的变化趋势,对本地区的生态及农业生产具有指征意义,为决策层制定防治对策提供科学依据。

Research on the Water Storage and Water Requirement of Ebinur Lake Based on RS Technology

Ebinur Lake is very shallow,flat bottom,depositing thick sand and silt.According to the water yield balance and characteristics of the Ebinur Lake,the mathematical model of water storage and water requirement was established.The data about the Ebinur Lake area is one of the important parameters,and is interpreted and gained by using RS technology and combining with resources satellite imagery and Modis data.The lake area change trend could be forecast based on the data of Lake Water storage and water demand.The research has some indication significance to the local ecological environment and agricultural production,and provides scientific basis for decision-making.
