【摘要】：选取山东省17个地级市为研究对象,根据影响山东农业旱灾的自然环境、经济环境、社会环境3方面因素确定了指标体系,构建了山东省农业干旱脆弱性区划层次分析模型,建立了判断矩阵,对山东省农业干旱脆弱性情况作了评估研究,并绘制出山东省17地市农业干旱脆弱性区划图。结果表明:在2000—2013年的14年间,山东省农业干旱脆弱性评价为不脆弱的城市有5个,轻微脆弱的城市有4个,脆弱的城市有4个,强脆弱的城市有3个,极端脆弱的城市有1个。山东省农业干旱脆弱性空间分布格局,全省大致是东南与西北方向低,中部与西南方向高,脆弱性区划的结果反映出山东省农业干旱风险程度的地域性差异,脆弱性较高的地市应作为农业干旱灾害防御的重点区域。
[Abstract]:This paper selects 17 prefecture-level cities in Shandong Province as the research object, determines the index system according to the natural environment, economic environment and social environment that affect the agricultural drought in Shandong Province, and constructs the hierarchical analysis model of agricultural drought vulnerability regionalization in Shandong Province. The judgment matrix is established, the agricultural drought vulnerability in Shandong Province is evaluated and studied, and the map of agricultural drought vulnerability in 17 cities of Shandong Province is drawn. The results show that: during the 14 years from 2000 to 2013, In Shandong Province, agricultural drought vulnerability was assessed as not fragile in five cities, slightly fragile in four, fragile in four, and strong in three. There are 1 extremely fragile cities. The spatial distribution pattern of agricultural drought vulnerability in Shandong Province is generally low in southeast and northwest, and high in central and southwest. The results of vulnerability zonation reflect the regional differences of agricultural drought risk in Shandong Province. Cities with high vulnerability should be the key areas for the protection of agricultural drought disasters.
