资源一号02C卫星在格尔木河洪积扇前缘地下水溢出带调查中的应用

Application of ZY1-02C satellite data to the survey of groundwater overflow zone in the front of alluvial-pluvial fan zone of Golmud River

以格尔木河洪积扇前缘地下水溢出带为研究区,资源一号02C（ZY1-02C）卫星影像为数据源,基于区域遥感水文地质解译理论方法,从图像处理、信息提取及综合解译分析等方面进行研究,探索了在西北干旱/半干旱盆地扇前缘利用ZY1-02C影像解译泉点、泉集河及地下水溢出带等水文要素的工作方法.通过实际应用结果表明,ZY1-02C卫星影像具备丰富的地表信息,图像解译标志清晰,能够较好地反映出洪积扇前缘地下水溢出带的形态特征和分布规律,实践证明ZY1-02C卫星影像在干旱/半干旱区的水文地质调查中有着良好的应用前景.

Based on field hydrogeological theory and remote sensing geological interpretation method, taking the groundwater overflow zone in front of alluvial-pluvial fan zone of the Golmud River as the study area, and using the satellite data of ZY1-02C as the data source, the authors explored the interpretation methods of hydrological factors such as springs, spring set rivers and groundwater overflow area in the front of alluvial-pluvial fan zone in inland arid basin with ZY1-02C data. In this practical application results, the ZY1-02C satellite images yielded rich surface information and clear image interpretation marks, which reflect the morphological characteristics and distribution of the groundwater overflow zone in the front of the alluvial fan well. This experiment proves that ZY1-02C satellite has a good application prospect for hydrogeological survey in the arid / semi-arid area.
