摘　　要：以永州地区为研究区域,利用NSIDC提供的2008年1月1日至2月10日的MOD10A2数据以及永州地区11个地面气象观测站资料,对比监测永州地区积雪变化情况。结果表明,MOD10A2遥感图像能真实反映山区降雪场的不连续、离散性,数据只能反映积雪变化,但不能反映冰冻灾害;地形对永州积雪分布有着显著影响。Taking Yongzhou area as the research area, the changes of snow cover in Yongzhou area were compared and monitored using the MOD10 A2 data provided by NSIDC from January 1 st,2008 to February 10 th, 2008 and the data from 11 ground meteorological observation stations in Yongzhou area. The results showed that the remote sensing image of MOD10 A2 could truly reflect the discontinuity and dispersion of snowfall field in mountainous areas. The data could only reflect the change of snow cover, but could not reflect the frost disaster. The terrain had a significant impact on the distribution of snow in Yongzhou.
