| 摘 要： | 扎陵湖、鄂陵湖是黄河源区两个最大的淡水过水湖,对黄河源区径流量与生态环境有很大影响。本文利用1976-2006年间四个不同时相的卫星遥感影像(MSS/TM/ETM+/CBERS)对扎陵湖、鄂陵湖湖面面积变化进行监测,提取水面分布范围,获得了扎陵湖、鄂陵湖湖面动态变化的数据,为掌握近三十年扎陵湖、鄂陵湖变化提供了可靠依据。近30年扎陵湖鄂陵湖水面变化是气候变化、人类活动、地质构造作用等多种因素综合作用的结果。

| Abstract: | The Ngoring Lake and Gyaring Lake,two largest lakes at the upper reaches of the Yellow River,play an important role in the runoff and environment of the riverhead area of the Yellow River.The thesis used four-phase remote sensing images(MSS/TM/ETM+/CBERS,1976-2006) to monitor water surface changes and extract water spreading range information of the two lakes in recent 30 years.The changes of Gyaring Lake and Ngoring Lake were attributed to the synthetic actions such as climate change,human activities,geologic structure evolution,etc. |
