摘　　要：内蒙古细毛羊(简称细毛羊)是内蒙古牧业一项支柱产业。为探究内蒙古脆弱生态环境下细毛羊放牧期气象灾害风险,减轻气象灾害可能造成的损失,指导救灾物资库建设及按季节救灾备资、调配工作,对细毛羊放牧期统计分段,归纳主要灾害性天气,利用研究区域周边15个气象站日资料、2014年社会经济数据、土地利用数据及DEM数据,构建基于灾害学的量化指标体系,熵权重计算,通过GIS技术得出细毛羊放牧期不同时段气象灾害综合风险区划。结果表明:内蒙古细毛羊主产区气象灾害风险呈东-西向带状分布,接羔保育期和配种期为东高西低,剪毛期和打草期为东低西高。Fine-wool sheep is a pillar animal husbandry industry in Inner Mongolia. In order to explore the risk of meteorological disasters in the grazing period of fine-wool sheep,and reduce the possible damage caused by meteorological disasters,the quantitative disaster index is calculated by GIS basing on disaster science using the daily data of 15 meteorological stations around the study area,socio-economic data in 2014,land use data and DEM data,and finally that is carry out the meteorological disaster comprehensive risk zoning of grazing period. The results show that the risk of meteorological disasters in the main producing areas of Inner Mongolia is the east-westward zonal distribution. It is distributed by east-high-west-low distribution on Lambing and breeding period,and east-low-west-high on shearing and preparing forage period.
