深圳市气传致敏花粉调查及其与气候条件相关性研究

应用Burkard采样器于2012年1月1日至2013年12月31日对深圳市气传花粉浓度进行采样调查,并运用统计学方法分析结果数据.深圳全年均有花粉飘散,每年出现2次花粉高峰期,在春季﹙2～4月﹚以木本花粉为主,在秋季﹙9～12月﹚以草本科花粉为主.调查的主要科属花粉种类基本相同,依次为禾本科、松科、木麻黄科、杉科、大戟科、桃金娘科等.气传花粉受气候条件影响很大,每日花粉含量及分布规律与日照时数正相关,而与相对湿度和降雨量负相关.深圳全年都有花粉传播,出现春季和秋季2个花期,且花粉浓度、种类及分布规律与气候条件相关性很大.

A Survey on Airborne Pollen in Shenzhen and to Analyze Its Relationship with the Weather Conditions

The concentration of airborne pollen in Shenzhen city was monitored with Burkard traps from January 1,2012 through December 31,2013,and the results were analyzed using statistical methods.The investigation revealed that there was airborne pollen throughout the year,with some differences in genera and numbers of pollen,and two peaks appeared throughout the year: the first peak was in February through April,the second peak was in September through December.The dominant pollen taxa at the three heights were similar:Gramineae,Pinaceae,Casuarinaceae,Taxodiaceae,Euphorbiaceae,and Myrtaceae.The major meteorological factors differed in the two pollen seasons.The daily pollen concentration was positively correlated with sunshine weather and negatively correlated with RH and rainfall in the flowering season.There was airborne pollen throughout the year,and two peaks appeared throughout the year in Shenzhen city.The distribution and concentrations of airborne pollen in the atmosphere were influenced by composite factors such as the season and meteorological factors.
