珠江三角洲及珠江口海区的空气微生物含量

THE CONTENT OF AIR BORNE MICROBIAL PARTICLES OVER THE DELTA AND ESTUARINE AREA OF ZHUJIANG RIVER

１９９４年６，７月，调查了广州、深圳、珠海及珠江口海区的空气微生物粒子沉降量状况。发现空气微生物粒子总量、真菌粒子量、真菌粒子数／总菌粒子数百分比在三市中不一致。这三种数据一般是陆上的高于海上。随着距陆的增加，都市影响的减弱和海面的开阔，空气微生物含量呈减少之势，显示出海洋新鲜空气对陆上污染空气的调节、净化作用。文中还分析了空气微生物有关参数与气温、风力或相对湿度间的相关关系。

uring June-July,1994,investigations were conducted on the state of precipitation of air borne microbial particles over Guangzhou,Shenzhen and Zhuhai in the delta and estuarine area of Zhujiang River. It is discovered that of the 3 cities, the highest precipitation of air borne microbial particles, fungi particles and fungi particles/total microbial precipitation % are in Shenzhen and Zhuhai respectively. Generally, the three kinds of data which are obtained from overland are higher than those from over sea water. With the increase in distance from land, reduction in city influences and extension of the sea surface, the precipitation of air borne microbial particles shows a decreasing tendency.This study shows that fresh sea air has regulative and pun factory effects towards polluted air over the land. The paper analyses the correlative relationships between some parameters of air borne microbes and relevant temperature, wind force or relative humidity respectively.
