Abstract
Using the meteorological data of visibility, relative humidity etc.and environmental data of PM2.5concentration etc.from February 2016 to March 2017 in Hefei City of Anhui Province,the time-distribution characteristics of haze weather and its effect on agriculture in Hefei City were analyzed by two-dimensional scatter plot and linear analysis method.The results showed that July was the lowest frequency of haze hours per month at 0.5% in a year and December was the highest at 38.0%,the annual average was 14.4%.The daily distribution of haze hour frequency was opposite to that of visibility,the lowest frequency of 5.2% occurred at 15:00, and the highest frequency of 27.9% occurred at 05:00.The frequency of haze days were basically the same with the haze hours throughout the year.The maximum value appeared in December at 61.3%and the minimum value in July at 0,the average haze day of the year was 8 days.The time-distribution characteristics of visibility and haze were closely related to the concentration of PM2.5,the visibility was negatively correlated with the concentration of PM2.5, and the frequency of haze was positively correlated with the concentration of PM2.5.Haze weather had adverse effects on agricultural production.关键词
