摘要
目的探讨Durham采样器和自动实时采样器2种方法采集大气花粉量的优缺点以及二者监测结果的相关性。方法在相同的高度和地点设置Durhum花粉采集仪和KH3000-1自动花粉采集仪,监测相同时间段的大气花粉浓度,分析2种方法采集的大气花粉浓度以及二者监测结果的相关性。结果 Durham采样器操作比较繁复,需要镜检人员有丰富的植物学专业知识,优点是可以分辨花粉的种属,对于了解一个地区不同种属花粉的飞散时段有重要意义;KH3000-1采样器实现了实时花粉计数,可高效地采集花粉,减少了显微镜计数的复杂工作,节省大量时间和体力。缺点是不能分辨花粉的种类。结论 2种监测仪监测到的花粉开始时间和高峰时间一致,但KH3000-1采样器易受花粉颗粒大小和气象因素的影响,结果可出现异常增高或减少。
Objective To analyze the correlation between the counting results of Durham pollen sampler and automatic pollen monitor, discuss the advantages and defects of two instruments. Methods Durham sampler and KH3000-1 automatic pollen monitor were set up next to each other on the same altitude. Airborne pollen concentrations were measured at the same time. Results Durham sampler has the merit of low cost and can classify the granules that adhere to the sampling surface, but pollen counting using Durham sampler require much time and skilled labor; KH3000-1 automatic pollen monitor count pollen particle using laser light in real time for computer processing, without the counting using a microscope, but it is difficult to distinguish pollen species. Conclusion The onset and peak time of pollen concentration measured by two devices were consistent, the results of automatic pollen monitor affected by pollens particle size and meteorological factors.
