摘要/Abstract

摘要： 以呼伦贝尔市16个气象台站1971—2014年逐日气象干旱指数MCI为基础,根据自然灾害风险区划的基础理论,综合土壤、人口、有效灌溉面积等9项社会经济指标,使用层次分析法建立呼伦贝尔市干旱灾害风险区划模型。在模型的基础上借助GIS技术和遥感技术绘制空间分辨率为1km×1km的干旱灾害风险区划图。结果表明:大兴安岭以西的呼伦贝尔草原地区的干旱灾害风险普遍较高,阿荣旗、扎兰屯等农业生产旗市也有干旱风险高值区存在,而牙克石、根河等地多林地和山地,干旱风险相对较低。建议在干旱高风险区增加防旱抗旱设施,合理安排和规范农牧业生产活动。

Abstract: Based on the MCI index of 16 meteorological stations in HulunBuir city from 1971 to 2014 and the theory of natural disaster risk zoning,a model for the establishment of drought disaster risk zoning was established.Based on the GIS technology and remote sensing technology,the risk zoning map at the spatial resolution of 1km×1km was drawn.The risk zoning map showed that HulunBuir grassland drought disaster risk was generally high,the lack of infrastructure and drought resistance,agricultural production in Arong county and Zhalantun city had high drought risk values,but it was relatively low in Yakeshi city and Genhe city which had many mountains and forests.It was suggested that we should strengthen drought-prevention and drought-resistance facilities in drought-prone areas and rationally arrange and standardize agricultural and animal husbandry production activities.

Key words: MCI index;Risk zoning of drought disaster;HulunBuir city
