| 摘 要： | 该研究提出了用于西藏雪灾监测与评估的方法,该方法结合遥感与地理信息系统,以MODIS数据得到的归一化雪盖指数(NDSI)为基础,同时估算厚云区的积雪覆盖的可能性,综合考虑包括DEM、道路等区域基础地理信息系统数据,对2007年3月中旬发生在西藏南部的一次大雪灾进行了监测与评估.结果表明,该方法能够有效地提取积雪覆盖区域,并对雪灾发生面积进行估算. |

| Abstract: | An applicable approach has been developed in the study for the monitoring and evaluation of snow disaster in Tibet.The approach,which based on the normalize difference of snow index(NDSI) retrieved from MODIS,DEM and corresponding GIS data was used to analyze the snowstorm happened in mid-March 2007 in southern Tibet.Results indicated that the new approach was able to provide an accurate estimate of snow cover area in southern Tibet.Thus it can be concluded that the approach can be used as an efficient alternative for snow cover monitoring and snow disaster evaluating in Tibet. |
