安徽黄山太平湖风景区空气质量评价

Air Quality Evaluation of Taiping Lake Scenic Area in Huangshan,Anhui

以黄山太平湖风景区为研究对象,在湖周边设置5个具有代表性的观测点,同步观测其空气离子浓度及主要气象要素。结果表明,所设观测点空气负离子浓度呈现出双峰型曲线,峰值每天先出现在10:00;低谷基本都出现在12:00左右;14:00出现第2个高峰值,之后逐渐下降。除1处空气有轻度污染外,其他4个观测点的空气质量均达到清洁标准。空气负离子浓度与相对湿度呈正相关,与温度呈显著的负相关。对太平湖风景区的空气舒适度分析显示,区域内空气均达到良好的舒适程度,适宜观光旅游。

Taiping Lake Scenic Area in Huangshan was taken as the study subject,and five representative observation points were set up around the Lake,including Gold Island,Longyaozhai,Tianxiataipingcheng,Lilac Park and Taiping Bridge for synchronous observations of the air ion concentration and main meteorological factors.The results showed that the air ion concentration at the observation points presented bimodal distribution：the peak first appeared at 10：00 and then 14：00 while both low points around 12：00,and after the 2nd peak,the concentration gradually decreased.Except for the mild air pollution at TaiPing Bridge,the air quality at the other 4 points reached the standard of cleanliness.Air anions concentration was positively correlated with relative humidity but negatively correlated with temperature.Finally,the analysis on air comfort at Taiping Lake Scenic Area showed that the air there reached good comfort level,suitable for sightseeing
