中文摘要	为了利用MODIS资料对沙尘暴的范围和强度进行定量判识,应用2002--2004年多次MODIS资料,通过对沙尘暴、云、雪和沙漠光谱特征的分析,构建了定量判识沙尘暴范围和强度的两个沙尘指数.利用2002-2007年数次沙尘暴过程对沙尘指数的判别效果进行检验,表明构建的两个MODIS沙尘指数能够有效地监测沙尘暴的范围和强度,且方法简单,适用于业务应用.针对目前西北沙尘暴遥感监测业务服务以定性图像为主,服务产品较为单一的问题,对MODIS沙尘暴判识方法进行业务化,并结合GIS进行沙尘暴影响范围的分析,开发研制了自动运行的MODIS沙尘暴监测和影响评估业务系统.系统具生成沙尘暴MODIS影像图、沙尘暴范围和强度遥感监测图、沙尘暴影响土地类型图、全国各省(直辖市)沙尘面积统计表、全国不同土地类型沙尘暴影响面积统计表、甘肃省各县沙尘暴的影响面积统计表和甘肃省不同土地类型沙尘影响面积统计表等功能,为沙尘暴定量和精细服务提供了丰富的产品.
英文摘要	Based on the analyses of the spectral characteristic of dust storm, cloud, snow and desert using the several MODIS data during the period from 2002 to 2004, two dust indices were constructed, which can determine quantitatively the scope and intensity of dust storm. The test results in several storms from 2002 to 2007 indicated that the above-built dust indices could effec-tively determine the scope and intensity of dust storms, and are proved to be simple and operable. In order to solve the actual issue that the present service product of remote sensing monitoring of dust storm is mainly simple and qualitative images, a new evaluating system was developed to monitor the dust storm based on MODIS data, which can offer not only MODIS image of dust storm, but the remote sensing monitoring image of the scope and intensity of dust storm, the plot of land classifications affected by dust storm, the statistics of dust area in different province, the statistics of area affected by dust storm for different land classification in China, and the statistics of area affected by dust storm for different county and different land classification in Gansu province. The new system is able to provide various products for the monitoring of dust storm in quantitative and fine service way.
