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.
