去年12月7日,北京降了入冬以来最大的一场雪。当北京人正为这突如其来的雪惊喜的时候,却发现,雪变成了灾——降雪使北京环城路的交通几近瘫痪。下班的市民撂在路上、汽车上五六个小时。时过境迁,但我们还是要问,一场不算大的雪尚且如此,城市防灾减灾功能怎的这般脆弱? On December 7 last year, Beijing dropped the biggest snowfall since entering winter. When the Beijingers were surprised by the sudden snow, they found that snow had become a catastrophe - snowfall nearly paralyzed the traffic around Beijing’s Ring Road. Commuters 撂 on the road, the car five or six hours. The passage of time, but we still have to ask, is not a big snow still so, how the city disaster prevention and mitigation function so fragile?
