Abstract: Accurate monitoring and forecasting of allergenic pollen concentration is not only the basis for the prevention of pollen allergy but also an important part of meteorological services.In the context of climate change and urbanization, there is an increasing trend of pollen allergy, leading to an urgent need for accurate and timely allergenic pollen monitoring and forecasting products to improve the defensive capability of sensitive people against allergy risks.Allergenic pollen collection techniques as well as the current status and the future development trend of the monitoring and forecasting methods for allergenic pollen are analyzed, together with the comparison of the characteristics of various methods.And then we discuss the future development direction of the monitoring and forecasting techniques so as to provide reference for the development of allergenic pollen monitoring and forecasting operation in China.
