2005～2015年新疆冰川与常年积雪变化监测研究

Monitoring Research on Glaciers and Perennial Snow Change in Xinjiang from 2005 to 2015

以2015年新疆维吾尔自治区第一次全国地理国情普查成果为基础,以覆盖新疆的2005年遥感影像数据为数据源,利用行业专题数据,采用遥感影像解译、数据编辑与整理、统计分析等技术与方法,实现新疆冰川与常年积雪分布及变化信息的快速、准确获取,通过统计分析对新疆冰川与常年积雪近10a的变化状况进行了分析,结果表明2005~2015年新疆冰川与常年积雪总面积减少了1945km^2,年均退缩率为8.06%。

Based on the first geographical conditions census results of Xinjiang Uygur Autonomous Region in 2015,taking the remote sensing image data of Xinjiang in 2005 as data source,combining with industry special data,we used the remote sensing image interpretation,data editing and sorting,and statistical analysis techniques to acquire the glaciers and perennial snow distribution and change information in Xinjiang accurately and quickly.Then,we analyzed the changes of Xinjiang glaciers and perennial snow in recent 10 years. e results show that the glaciers and perennial snow total area in Xinjiang reduces 1 945.31 km2 from 2005 to 2015,and the annual retreat rate is 8.06%.
