摘　　要：对空气致敏花粉污染概念的提出 ,空气致敏花粉污染的特点和影响因素 ,花粉采集方法的改进以及空气致敏花粉污染的研究进展等方面进行了总结 ,指出了研究中存在的问题 。Pollinosis, a pollen-related disease, is caused by airborne allergenic pollens from certain plants. The prevalence of pollinosis has happened in recent decades. In order to prevent pollinosis, it is of great importance to do the research on airborne allergenic pollen. The advances in airborne allergenic pollen are briefly reviewed in this article pertaining to five aspects of the topic. Firstly, the concept of airborne allergenic pollen was introduced. Secondly, the characters and influential factors of airborne allergenic pollen were summarized. Airborne allergenic pollen has territorial and seasonal characters. There are some influential factors such as the type and quantity of allergenic pollen, ecological factors and contrived factors. Thirdly, the paper elaborated the improvements of pollen collectors. Several primary pollen collectors were described and compared here. For example, Burkard spore trap is based upon the same principle as the Hirst device, but the former allows uninterrupted sampling through seven days. Fourthly, the advances in airborne allergenic pollen were concluded from four different research fields. Some researchers investigated airborne allergenic pollen and several types of airborne allergenic pollen were identified. It is also very important for researchers to study pollen of different allergenic plants, to extract the substances out of them that cause pollinosis and to produce allergenic medicaments in diagnostic and medical senses. Other studies revealed the correlation between allergenic pollen and air pollution. One of these studies showed that the pollutants seem to make the surface of the exine more fragile, so triggering a mucosal reaction, making them more exposed to pollen allergens. At the same time, people took several precautionary measures, e.g. pollen forecast, to prevent the prevalence of pollinosis. There are many different remedies about pollinosis, among which there is a so-called immunotherapy. Fifthly, some problems about the study on airborne allergenic pollen an
