摘要(Abstract)：

为了基于ICESat/GLA14测高数据对黄土高原重要水库水位变化进行动态监测,该文首先利用Landsat 8遥感影像提取黄土高原的水体边界,并参考ICESat/GLA14数据的分布状况在黄土高原东部选取了册田水库,中部选取了文峪河和王窑水库,西部选取了刘家峡、寺口子和沈家河水库;然后以10cm为阈值对ICESat/GLA14数据进行筛选,从而获得了所选水库水位长时间序列的动态变化;最后将册田和文峪河水库的ICESat/GLA14测量水位与实测水位进行比较,验证ICESat/GLA14监测水库水位变化的准确性。研究结果表明:东部水库水位呈明显下降趋势;中部水库水位在2005年5月明显下降,其后逐渐恢复,整体呈下降趋势;西部水库水位变化不大;ICESat/GLA14测量的水库水位变化与实测水位变化基本一致。

关键词(KeyWords)： 水位变化;ICESat/GLA14;重要水库;黄土高原
