基于遥感分析的艾比湖流域植被分布研究

A Study of the Vegetation Distribution of Ebinur Lake Valley Based on the Remote Sensing Analysis

随着耕地和绿洲面积的增加和生态环境的恶化,导致艾比湖湖水面积逐年缩小,艾比湖流域的生态恶化事实上已成为困扰新疆的第二大生态问题,艾比湖干缩导致的地下水位下降,使该流域周边地区荒漠化大大加快,荒漠化速度已高达每年38平方公里。该文基于遥感技术支持下,对艾比湖流域植被分布状况进行分析,利用遥感进行湿地监测,可以提高监测的时效性和准确性,以防止沙漠化。

With the increase of the arable land and the Oasis, the deterioration of the ecological environment narrows the Ebinur Lake area every year, which becomes Xinjiang＇s second largest ecological problems. The shrinkage of the Ebinur Lake leads to the dropping of groundwater level, which greatly accelerates the desertification of the surrounding basin area. The annual rate of the desertifieation reaches 38 square kilometers. Supported by the remote sensing technology, the authors have analyzed the vegetation distribution of the Ebinur Lake Valley. The use of remote sensing to monitor wetlands could improve the monitoring efficiently and accurately so as to prevent the desertification.
