| 摘 要： | 区域尺度积雪信息的时空监测对确定雪灾的影响范围及灾情等级划分具有重要意义。本文利用近10年的MODIS积雪产品,按月最大面积的规则合成;分析了新疆积雪覆盖面积的时空变化特征,结果表明:时间上,新疆积雪面积有减少的趋势。空间上,近10年新疆积雪季节内永久性积雪覆盖区域主要分布在阿勒泰山脉、天山北麓及沿昆仑山脉西南部。其中天山及阿尔泰山之间的河谷及盆地的草原积雪面积波动主导了新疆整体积雪总面积的波动。 |

| Abstract: | The spatial-temporal monitoring of regional snow covered area has important significance for the determination of regional snow disaster impact scope and disaster grade.The spatial and temporal changes pattern of snow cover in Xinjiang was analyzed by 10 years Aqua/MODIS snow products which were composed according to maximum area rule.The results indicated that snow cover fluctuated and had a decreasing trend,the permanent snow cover area was spatially distributed Altay mountains,northern parts of Tianshan and southwest part of Kulun mountians area,and the snow cover area changes were caused by the changes of snow cover in grassland area of basin between Tian shan mountains and Altay mountain area. |
