摘要

该文以中国雪灾高发区的西藏那曲地区为例

主要介绍了在试验区雪灾背景数据库支持下

利用NOAA/AVHRR卫星遥感资料对雪灾进行判别、预测及对灾情损失进行综合评估的一些技术和方法

其内容包括 :（1）用于雪灾危险等级分析与判定的判别模型 ;（2 ）用于灾情发展趋势模拟与预测的预测模型 ;（3）用于灾情损失综合评估与估算的评价模型。并运用这些模型对 1995年 2— 3月发生在西藏那曲的雪灾进行实时分析

其结果和实情基本吻合

能够满足应用要求

Abstract

The snow disaster monitoring and assessment were carried out by means of snow disaster monitoring and assessment system（SDMAS）which could be updated by using NOAA/AVHRR data in the main pastoral areas of our country.Some models

such as snow disaster distinguishing

forcasting and assessment

which were developed based on the spatial attribute

data from the spatial analysis and operation of SDMAS

and their application are introduced in this paper Some results from the operation of SDMAS are approximately identical with the records of disaster reports
