摘要: 2000年4月5日~7日袭击我国西北地区北部、华北、东北南部、黄淮地区的扬沙或沙尘暴波及到长春市,带来了大量降尘的同时,还有大量细菌侵入。据长春市中西部解放立交桥和南湖公园取样测定,4月7日市区"泥雪"湿沉降,经实验室48 h细菌培养,需氧细菌含量解放立交桥每毫升样品8.9万个、南湖公园10.5万个,市区每平方米"泥雪"携带细菌量平均达6.4亿个左右;细菌生化反应鉴定,未发现致病菌存在,杂菌数量及种类很多,解放立交桥与南湖公园样品细菌种属组成有一定差异。

Abstract: The sandstorm broadly occurred in North of China from April 5 to April 7,2000 had spread to the Changchun City area.There were large amounts of bacteria intruding along with descending dust.Analysis to samples from Nanhu Park and Jiefang cross-bridge in Changchun City showed that one-milliliter sample water contains bacteria up to 89×103 units and 105×103 units,respectively.It was deduced that there were 6.4×108 bacteria within one square meter in urban area.The bacteria species belong to various kinds,and just as well no pathogenic species.This study alarms that other than the visible environmental effect of sandstorm,the urban micro-ecosystem is very possibly under the pollution of bacteria intruding with the remote sand-dust.

Key words: remote sand-dust, bacteria, Changchun City
