2008年初我国低温雨雪冰冻对重点行业的影响及致灾成因分析

Disasters and Its Impact of a Severe Snow Storm and Freezing Rain over Southern China in January 2008

运用典型事例和大量的数据,分析了2008年初中国南方低温、雨雪、冰冻灾害对交通、电力、通讯、农业和林业等重点行业以及人民生活各个方面的影响。指出天气气候特点、灾害发生的特殊地域和时间以及不同行业在低温、雨雪、冰冻灾害下的敏感性是致灾因素。要应对这类低温、雨雪、冰冻灾害,并最大限度的将其影响降至最低,就应在电力、公路、铁路以及建筑工程等的规划设计过程中,加强灾害性天气气候的可行性论证和提高设计标准,同时应提高对冬季低温、雨雪、冰冻灾害的预报能力,建立完善的预报系统和信息发布等防治体系,加强应对极端气象灾害的科普宣传,提高民众自救互救能力。

The impact of the severe snowfall and freezing rain disasters on transportation,electric power,communication,agriculture,forestry and human life over southern China in January 2008 are investigated based on collected observational data.The severe weather,climate background and the sensitivity of disasters impact on various departments,such as transportation,electric power,communication,agriculture,forestry under snow storm and freezing rain are the main reasons of disaster formation in special periods and places.To reduce the loss of such disasters,it is necessary that the design standard of transportation,electric power,communication,agriculture and forestry should be improved,the capability of severe snow storm and freezing rain prediction should be improved,the information issuing system should be developed,the knowledge of defencing natural disasters should be propaganded,so that people can provide help for others and themselves when disasters occurred.
