摘要:

青藏高原作为地球第三极增温明显,相关研究多集中于青藏高原冰雪动态,很少关注冰雪消融后岩漠的变化。岩漠通过地气相互作用影响着全球气候变化的区域差异。本文通过梳理青藏高原冰雪、冰雪消融区、岩漠动态变化遥感监测方法体系,着重分析了各遥感数据来源及提取方法的优缺点和适用性,并对基于遥感技术条件下青藏高原冰雪动态监测、冰雪消融区岩漠动态变化监测的数据来源、研究方法与技术进行了总结。目前,青藏高原冰雪动态变化遥感监测数据来源多样、研究方法成熟,而冰雪消融区岩漠动态变化遥感监测尚未形成系统研究。在人为干扰不明显背景下,青藏高原冰雪消融区岩漠的动态变化,在一定程度上也可作为对冰雪变化遥感监测的补充。

Abstract:

The Qinghai-Tibet Plateau is sensitive to climate change. At present, relevant researches mostly focus on the dynamic changes of ice and snow in the Qinghai-Tibet Plateau, and seldom pay attention to the dynamic changes of the rocky desert left by the melting ice and snow. Through the earth-atmosphere interaction, rocky desert may change the regional heterogeneity of climate at a large scale. This paper sorted out the extraction methods of remote sensing monitoring of ice and snow melting and rocky desert dynamic changes in the Qinghai-Tibet Plateau, and analyzed the advantages, disadvantages and applicability of various remote sensing data and extraction methods. We also summarized the data and research methods of the dynamic monitoring of ice and snow and the dynamic changes of the rocky desert in the Qinghai-Tibet Plateau. At present, the remote sensing monitoring data of the snow and ice dynamic changes in the Qinghai-Tibet Plateau are diverse and the research methods are mature. However, the remote sensing monitoring of the rocky desert dynamic changes left by the melting ice and snow has not yet formed a systematic study. Besides, under the condition of insignificant human disturbance, the dynamic changes of the rocky desert in the ice and snow melting area can also be used as a supplement to remote sensing monitoring of ice and snow dynamic changes.
