摘　　要：综合利用遥感信息和地面观测资料,研究建立了适合内蒙古自治区特点的干旱遥感监测模型,通过查阅干旱指数监测的历史干旱状况,结合地面实测数据分析,形成对区域干旱监测的分级遥感图。针对干旱监测评估中定量服务所面临的困难,文中研究应用大量的社会经济信息,基于GIS的空间分析功能,对干旱影响面积、影响范围以及影响的各类社会经济指标进行了评估,使干旱遥感监测评估研究从定性到定量和精细化,丰富了干旱监测评估研究的内容,提高了业务服务质量。在上述研究的基础上,使用计算机编程技术,建立了基于空间信息的干旱监测评估系统,并以2010年6月份内蒙古干旱监测为例,进行了干旱等级划分及监测评估分析,取得了可观的应用效益。By using remote sensing information and ground observation data,the model of drought monitoring for Inner Mongolia has been established.According to consulting the history of drought situation monitored by drought index and analyzing the ground truth data,the drought classification map for regional drought monitoring was made.For the difficulties of quantitative assessment of drought monitoring services,based on the GIS spatial analysis function and a large number of social and economic data,the affected area,region and some socio-economic indicators by drought were evaluated.The remote sensing of drought monitoring and evaluation from qualitative to quantitative and the content of the study of it has been refined and enriched,and the quality of service has been improved.On the basis of above work,by use of computer programming technology,the monitoring and evaluation system of drought based on special information was established.Take the drought monitoring in June 2010 of Inner Mongolia for an example,by classifing the drought level and analyzing the result of monitoring assessment,we achieved a considerable results of applications.
