摘要
对杭州五云山疗养院、钱江疗养院、东方航空疗养院具代表性植物群落中的空气正、负离子浓度进行了测定,并进行相关评价。结果表明:①春季空气负离子浓度和空气清洁度均高于冬季;②疗养院冬春两季空气负离子浓度和空气清洁度显著高于市区;③总体来说,空气负离子浓度和空气清洁度上海铁路局钱江疗养院>五云山疗养院>东方航空疗养院;④随着气温的升高,负离子浓度下降;随着湿度增加,负离子浓度上升;⑤一日中空气负离子浓度随光照加强而增加。
From December 2008 to May 2009,determinations were conducted on positive and negative air ions concentration of typical plant communities at the sanatoriums in Hangzhou,Zhejiang province.The result showed that negative air ions concentration and clean index in all tested plant communities in the spring was higher than that in the winter,and that at any sanatorium in the summer or winter was evident higher than that in the urban area.The order of the negative air ions concentration and clean index was： Qianjiang Sanatorium Wuyunshan Sanatorium CE Sanatorium.There was negative correlation between negative ions concentration and temperature,but positive correlation between anions and humidity.
