廊坊地区春季花粉浓度变化特征及花粉过敏等级的初步研究

Preliminary Study on the Variation Characteristics of Pollen Concentration and Pollen Allergy Grade in Langfang Area in Spring

利用廊坊国家气象观测站LJHF3000全自动花粉监测仪观测数据,分析了2021年春秋季花粉变化特征,并与同期气象条件进行相关性研究,初步探究气象条件对空气中花粉扩散的影响。研究发现,廊坊市城区花粉浓度最高主要在春季(4—5月)。廊坊城区气传花粉的浓度受基本气象要素的影响比较显著。适宜的温度和大气环境气流的快速流动,可以促进花粉的传播;在一定强度的风力作用下,风的流动、震荡作用对花粉起稀释传播作用,有利于花朵接收、控制花粉粒粘黏授粉。4—5月为花粉高峰期,诱发花粉过敏症可能性较大。

Based on the observation data of LJHF3000 automatic pollen monitor at Langfang national meteorological observation station,the analysis of pollen change characteristics in spring and autumn of 2021 is completed,and the correlation study with the meteorological conditions in the same period is carried out to preliminarily explore the impact of meteorological conditions on pollen diffusion in the air.The study found that the highest pollen concentration in Langfang city was mainly in spring(April to May).The concentration of airborne pollen in Langfang city was significantly affected by the basic meteorological factors.The suitable temperature and the rapid flow of air flow in the atmospheric environment promote the propagation of pollen.Under the action of a certain strength of wind,the flow and vibration of the wind play a role in the dilution and propagation of pollen,which is conducive to the reception of flowers and the control of sticky pollination of pollen grains.The peak period of pollen is from April to may,which is likely to induce pollen allergy.
