| 摘 要： | 基于GIS技术,利用海拔、地形起伏度、1971-2000年各年5-9月平均冰雹发生次数、人均GDP、耕地百分比、平均耕地产值、烤烟种植面积等资料,从敏感性、危险性和易损性3个方面建立云南烟区冰雹灾害风险评价模型,对烟区冰雹灾害风险进行评价。结果表明,云南烟叶主产区曲靖、玉溪、楚雄等地冰雹灾害风险等级较高,需要加强灾害防御;滇西南烟区如思茅、临沧、德宏等地冰雹灾害风险等级较低,可适当增加烤烟种植面积。

| Abstract: | The mathematical model of the hail disaster risk assessment was established,by using of GIS,to evaluate the hail disaster risk in Yunnan tobacco planting areas from three aspects such as sensitivity,risk and vulnerability,based on the relief degree of land surface,average hail days from May to September,the average GDP,the percentage of cropland,and the average production value of cropland.The results showed that the gradation of hazard evaluation for hail disaster was high in Qujing,Yuxi and Chuxiong,which should be pay more attention to defense hail disaster.The gradation was low in the southwest of Yunnan,including Simao,Lincang and Dehong,where the planting areas of tobacco could be increased. |
