气候变暖导致的冰川退缩问题已引起了广泛关注, 青藏高原作为世界第三极, 其冰川积雪变化也成为全球变化研究的重要内容. 选取了2011年5-9月期间青藏高原扎当冰川及周边区域的HJ-1A/1B多光谱数据共13景, 通过最大似然法分类分别提取冰川区积雪面积, 并与该区域同期日平均温度数据进行了相关分析. 结果表明: 2011年5-9月研究区积雪面积呈现先减少后增多的总体变化趋势(由5月的37%, 降到6、 7月的18%, 到8、 9月份又回升到21%); 积雪面积变化和气温呈现高度负相关.

关键词: 积雪面积, 环境小卫星, 最大似然分类, 温度响应


Glacier variations results from global climate change. Global warming leading to glacier shrinking and snow cover decreasing has become a hot issue in the world. The Tibetan Plateau is the world's third pole and its glacier and snow covers change is also the important content in cryopsheric sciences research field. In this paper, we choose 13 multi-spectral images of HJ-1A/1B satellite, acquired from May to September, 2011 including Zhadang glacier. The snow cover areas in glaciated region were extracted from each of the 13 images by using the maximum likelihood classifier. The correlation analysis was performed between the extracted snow cover areas in glaciated region and the daily average temperature. The results show that the snow cover areas in glaciated region decreased first and then increased during the period from May to September, 2011 (37% in May, 18% in July and 21% in September respectively). In addition, the results also indicate the snow cover areas in glaciated region has an obviously negative relationship with the daily average temperature in the study site.

Key words: snow cover areas in glaciated region, HJ-1A/1B multi-spectral data, maximum likelihood classifier, air temperature response
