| 摘 要： | 利用1960-2009年全国542个站点的常规气象观测资料,从灾害成因角度筛选评估指标,建立灾害危险性评估的气象指标体系,基于不同强度频率的评估思路构建综合危险性指数,对中国低温雨雪冰冻灾害危险性进行评估和区划.结果表明:(1)中国大部地区属于低危险区,高危险区主要集中于黑龙江—吉林—辽宁东部—内蒙古东部、新疆北部、青海南部—西藏东北部—甘肃南部.南方绝大部分地区均处于极低危险区.(2)南方地区内部相对高危险区主要集中在四川中南部—云南东北部—贵州西部、湖南东部、安徽南部—江西北部、河南北部.(3)高危险区的分布与地形、纬度均有着密切的关系. |

| Abstract: | Based on the conventional observation data from 542 stations in China in 1960-2008, evaluation indicators are selected from the aspect of disaster causes and the risk assessment of meteorological index system is built. The risks of low temperature, rain/snow and freezing disaster are assessed and zoned in China by using the comprehensive hazardous index which is built on the assessment philosophy of different intensity frequencies. The result shows that most parts of China are in the low risk regions. The high risk areas are mainly located in Heilongjiang, Jilin, the east of Liaoning, the east of Inner Mongolia, the north of Xinjiang, the south of Qinghai, the northeast of Tibet, and the south of Gansu. Much of South China is located in the areas with the lowest risks, and some relatively high risk areas in South China are found in central and southern part of Sichuan, the northeast of Yunnan, the west of Guizhou, the east of Hunan, the south of Anhui, the north of Jiangxi, and the north of Henan. The distribution of the high risk areas is closely related to the topography and latitudes of these regions. |
