摘要： 为了掌握猕猴桃果实膨大期高温干旱灾害发生的风险水平和空间分布情况，进行陕西猕猴桃高温干旱风险区划研究，为果业部门开展猕猴桃生产的防灾减灾，以及猕猴桃高温干旱灾害保险设计、理赔以及避灾抗灾政策措施提供参考。本研究基于自然灾害风险形成原理，利用气象数据、基础地理信息数据、社会经济统计数据和历史灾情等方面资料，从致灾因子危险性、孕灾环境敏感性、承灾体易损性以及防灾减灾能力4个方面，构建陕西猕猴桃高温干旱灾害风险评估模型，利用GIS技术，开展陕西猕猴桃高温干旱风险区划研究。结果表明，重度风险区主要分布在关中东部渭河下游低海拔地区，该区域重度高温干旱灾害约3年1遇，同时存在约2年1遇的中度、1年1遇的轻度高温干旱灾害；中度风险区主要分布在关中中东部和陕南汉江下游两岸部分地区，该区中度高温干旱灾害2~3年1遇，同时存在3~4年1遇的重度灾害和少于1年1遇的轻度灾害；轻度风险区主要分布在关中中度风险区南部、北部和西部，以及陕南汉江及其支流两岸、金钱河、丹江及其支流两岸、南洛河两岸海拔较高的地区。

Abstract: In order to study the regional distribution on the risk of high temperature and drought disaster during the fruit expanding process for kiwifruit in Shaanxi, the risk zoning of it was carried out to provide scientific basis for fruit industry disaster prevention and reduction. According to disaster risk forming mechanism, the assessment model of high temperature and drought for kiwifruit was constructed by using meteorological data, basic geographic information data, socio-economic statistic data, and history disaster situation data, based on the factors, such as the risk of disaster causing, the sensitivity of disaster environment, the vulnerability of disaster body, and the ability of disaster prevention/reduction. Then the study on risk zoning of high temperature and drought for kiwifruit in Shaanxi were carried out by using GIS technology. The results showed that: the severe risk regions mainly distribute in the lower Wei River of Guanzhong, Shannxi; the severe risk of high temperature and drought was in every 3 years, the moderate of it was in every 2 years, and mild of it was in every 1 year meanwhile. The moderate risk regions mainly distribute in the middle-east of Guanzhong and Hanjiang Valley of southern Shaanxi; the moderate risk of high temperature and drought was in every 2-3 years, the severe of it was in every 3-4 years, and mild of it was less than every 1 year meanwhile. The mild rrisk regions mainly distribute in the southern, northern, and western moderate risk regions, and high altitude areas along Hanjiang and its tributaries, and Jinqian, Danjiang, Nanluo River.
