    摘要:

    以汗敖包嘎查为研究对象,从牧户微观尺度出发,利用嘎查内92户牧民实地调查社会经济数据、气象数据和遥感数据,应用自然灾害风险指数法、主成分分析法、加权综合法结合GIS空间分析技术,以栅格50m×50m的基础单元进行评价,通过对危险性、暴露性、脆弱性和防灾减灾能力4个因子的分析,构建了汗敖包嘎查内草原火灾的风险评价指标体系,并获取了汗敖包嘎查草原火灾风险分布图。结果表明:汗敖包嘎查草原火灾风险总体上中部高、两侧低,且南部区域风险性高于北部,中、高风险区占研究区总面积的66.71%,集中分布在研究区的中部、东部和南部。研究结果从微观尺度为草原火灾风险评价提供了新的视角和参考。

    Abstract:

    Taking Hanaobao Village as the research object, starting from the micro scale of the herdsmen, using the socio-economic data of the field survey of 92 herdsmen in the village, meteorological data and remote sensing data, applying natural disaster risk index method, principal component analysis method, weighted synthesis method combined with GIS spatial analysis technology, and using 250 m × 250 m basic grid as assessment unit, through analysis of four factors: risk, exposure, vulnerability, and disaster prevention and mitigation capabilities, the risk evaluation index system of the grassland fire in the Khanna sag was built, and the risk distribution map of the grassland fire was obtained. The results show that the risk of fire in the grassland of Hanaobao Village is generally high in the middle and low in both sides, and the risk in the southern region is higher than that in the north, medium and high risk areas accounted for 66.71% of the total area of the study area, centralized in the central, eastern and southern parts of the study area. The research results provide a new perspective and reference for the grassland fire risk assessment from the micro scale.
