摘　　要：测定扬州瘦西湖景区4种类型水体环境中的空气负离子密度,并以单极系数和安倍空气离子评价系数为标准对扬州瘦西湖景区空气质量进行评价。结果表明:空气负离子密度依次为石壁流淙(瀑水)>卷石洞天(跌水)>钓鱼台(湖水)>凫庄(湖水);空气质量均达到清洁水平,人体舒适度较高,其中,动态水域的空气质量达到A级(极清洁水平)、静态水域的空气质量达到B级(一般清洁水平)。测试数据经SPSS方差分析,4种水体环境中的空气负离子密度差异性显著。The air quality of the Slender West Lake,Yangzhou was evaluated by measuring the concentrations of aerocation and aeroanion in four typical landscapes in water body by means of ratio of cations to anions and air quality evaluation index. Results show that the aeroanion concentration in Shibi Liucong （waterfall） is the highest,followed in a decreasing order by Juanshi Dongtian （drop of water）,Diaoyutai （lake water）,and Fuzhuang （lake water）. Air quality of all the landscapes reached cleanliness level,and human comfort index was higher. Air quality of moving water body reached the desired level of cleanliness,and that of static water body reached common level of cleanliness. Analysis of variance proves that the differences in aeroanion concentration in the four areas are very significant.
