| 摘 要： | 利用HJ-1A卫星数据为主要数据,结合高程、温度和降水量等辅助数据,对柳州市2010年和2012年两次典型的雨雪冰冻灾害的光谱特征和空间分布特征进行分析,结果表明：雨雪冰冻灾害主要出现在海拔900m以上的山区,海拔越高,灾害越严重;降雨与持续低温是灾害出现的条件.

| Abstract: | Based on, HJ-1A satellite data as the main data, two ice-snow and frozen disasters of Liuzhou were analyzed in 2010 and 2012 with elevation, temperature, precipitation and other auxiliary data. The results showed that ice-snow and frozen disasters occurred mainly in the mountains over 900m, and higher elevation, the more serious disasters. Continuous rainfall and low temperature are conditions of disasters occurrences. |
