基于遥感和GIS的柴达木盆地冰雪湖泊演变分析
Analysis of glacier and lakes evolution in North Qaidam Basin based on remote sensing and GIS
摘要
Abstract
The North Qaidam Basin is located in the arid and semi-arid regions in northwest China. In order to study the re-sponse of the glacier and lakes in north Qaidam Basin to the climate change, satellite imagines of the area in recent 25 years are abstracted by using the technologies of remote topographic feature abstract and GIS spatial analysis, and the evolution characteris-tics of the glacier and lakes are analyzed. The analysis results show that the bigger Qaidam lake is stable while the area of smaller Qaidam lake changed a lot, which has enlarged by 60% after 2000; the area of the glacier shrieked rapidly after 2000, which threatened the future ecological safety.关键词
