摘要:: 利用MODIS和Landsat TM/ETM+遥感数据,得出研究区的积雪面积,同时结合精伊公路规划图及地形图,分析了公路沿线可能存在风吹雪和雪崩的危险区,并提出相应的防治措施。结果表明:研究区近5年来11月到次年3月是积雪最丰富时期,9月、10月、4月和5月积雪较少。近5年来积雪呈增加趋势,最大积雪时间集中在2009—2010年积雪季。MODIS积雪数据精度在积雪面积越大时,精度越高;积雪面积越小时,精度越低。精伊公路东线走廊K60以上路段和西线走廊K100以上路段风吹雪对公路影响较大;精伊公路北段的雪崩的可能性很小;东线走廊K60～K77段和西线走廊K90～K110段有一定的雪崩灾害;西线走...

Abstract:: Using MODIS and Landsat TM/ETM+ data, we analysis snow cover area of study area. And combining planning map of Jinghe to Yining highway and topographical maps, we indicate dangerous zones of snow drift and avalanche along the highway, and put forward relevant control measures. There are four results. Study area snow cover is the most abundant from November to next March in recent five years, and snow cover is less during September, October, Apirl and May. Recently snow cover is increasing trend, and Maximum snow cover time is 2009-2010 snow cover season in recent five years. The bigger is snow cover area, the higher is precision of MODIS snow data; the smaller is snow cover area, the lower is precision. Snow drift is great impact on the highway in over K60 of east highway and over K100 of west highway. The probability of avalanche is small in north highway. There are some small avalanches in K60-K77 of the east highway and K90-K110 of the west highway. K58-K90 of the west highway have some great avalanches. And some control measures is proposed.
