| 英文简介 | Glacier is the lifeblood for sustainable economic developing in arid and semi-arid areas，dust is one of the important factors that affect glaciers ablation，which can not be ignored. Many scholars used glacier ice core data，analyzed the impact of dust on glacier surface；or based on the remote sensing methods，analysed the response of glaciers to climate change；Few researched on the influencing mechanism of dust frequency，intensity and impact scope to glacier ， This study focus on using of HJ-1/CCD， LandSat/TM and EOS/MODIS data to establish a comprehensive identification algorithms of typical glacier/snow，which is combined with measured data and experiment result，and carry out the accuracy test and analysis. Based on the products of infrared difference dust index（IDDI）which have been consistency analysed and localized fusion，by using of the method of correlation analysis，significant test and hysteresis quality analysis，we comprehensive research on the influencing mechanism of dust frequency，intensity and impact scope to glacier，and expect to reveal the reasons for changes in some parts of glaciers from another aspect， while expanding the domestic satellite data being used in glaciology. |
