环境遥感信息分析法在干旱区找水中的应用——以内蒙锡林浩特地区为例

THE APPLICATION OF ENVIRONMENTAL REMOTE SENSING INFORMATION ANALYSIS IN SEEKING FOR WATER RESOURCE IN ARID AREAS TAKING XILINHAOTE AREA, INNER MONGOLIA AUTONOMOUS REGION AS EXAMPLES

从研究干旱区域地下水与植被关系入手，通过植被遥感信息分析，推断出浅层地下水的富水区；根据干旱区地表水主要受地下水补给这一规律，应用多时相遥感资料通过对区内巴彦布拉格湖水水域面积的动态分析，指出呼吉尔湖水接受深层地下水补给。上述解译成果为本区找水提供了方向，已得到后续物探、钻探工程证实。

Remote sensing information generally reflect the spectral characteristics of land surface environment which include vegetation, soil, surface water body. On the basis of researching the relationship between underground water and vegetation in arid area, the plentiful water_bearing areas underground have been defined by vegetation remote sensing information analysis. According to the regularity that the land surface water were mainly supplied by underground water, dynamic analysis of Bayanbulage lake area in this region were done by taking use of multi_temporal remote sensing information. This paper pointed out that Hujier lake was supplied by underground water of deep layer, the interpretation results have been testified by geophysical exploration and drilling. It can be a guide for seaching water in this region.
