【摘要】：基于1984-2014年新疆雹灾受灾面积、总成灾面积、农作物播种面积、新疆生产总值及以县为单位的雹灾频次等统计数据,构建雹灾经济损失指标和风险度指标,进行新疆冰雹灾害评估研究。其中雹灾经济损失指标可用于评价新疆雹灾经济损失的趋势变化,风险度指标可借助GIS空间信息处理技术形成新疆雹灾风险区划。研究表明:雹灾经济损失总体呈波动上升趋势,且受环境不稳定度的影响较大,二者保持着较好的正相关性。新疆冰雹灾害总体以中、低度风险为主,高风险次之。高风险区主要集中在喇叭形河谷地带的伊犁地区及其两侧的阿克苏、博州等地,建议通过调整农业产业结构、提升人工防雹能力等方式降低上述区域的雹灾损失。
[Abstract]:Based on the statistical data of hail disaster area, total disaster area, crop planting area, Xinjiang GDP and hail disaster frequency per county from 1984 to 2014, the economic loss index and risk index of hail disaster were constructed.To study the evaluation of hail disaster in Xinjiang.The index of economic loss of hail disaster can be used to evaluate the trend change of economic loss of hail disaster in Xinjiang, and the risk index can be used to form the risk regionalization of hail disaster in Xinjiang with the help of GIS spatial information processing technology.The results show that the economic loss of hail is fluctuating and rising, which is influenced by the degree of environmental instability and maintains a good positive correlation.The hail disaster in Xinjiang is mainly low risk, followed by high risk.The high risk area is mainly concentrated in the Yili area of the trumpet valley and its two sides, such as Aksu and Bozhou. It is suggested that the hail loss in these areas be reduced by adjusting the agricultural industrial structure and enhancing the ability of artificial hail suppression.
