摘　　要： [目的]探讨冬春季梅州市各功能区绿地的抑菌效应。[方法]2008年1～4月对梅州城区不同功能区绿地空气微生物浓度进行测定,计算抑菌率,并进行空气微生物污染程度评价。[结果]梅州市不同功能区绿地空气微生物浓度存在差异,商贸区(F)的平均微生物浓度最高,为21 334 CFU/m3,文教区(A)的平均微生物浓度最低,为3 794 CFU/m3,不同功能区间的绿地空气微生物浓度大小排序为商贸区、交通区、医院区、风景区、居住区、文教区;梅州市城区绿地中微生物组成的总趋势是细菌(53.7%)>真菌(34.5%)>放线菌(11.8%);影响绿地中空气微生物浓度的主要因素是绿地结构、温度、相对湿度等;除文教区(A)的绿地空气质量处于较清洁状态外,多数功能区的绿地微生物污染都达到或超出了轻微污染的程度,其中,商贸区(F)和交通区(E2)样点的空气质量最差,达到中度污染。[结论]绿地可以有效降低空气含菌数量,抑菌效应显著,但在一定程度上也受到周围环境的影响。 [ Objective ] The research aimed to study the antibacterial effects of urban greenspace in different function area of Meizhou City in winter and spring. [ Method ] The concentration of microbes in different function area of Meizhou City was determined from January to April in 2008. And the inhibitory rate was calculated. Then the pollution degree of microbes in air was evaluated. [ Result]The results showed that the concentration of microbes in different function area of Meizhou City differed. Commercial area （F） had the highest average concentration of 21 334 CFU/m^2. Culture and education area（A） had the lowest average concentration of 3 794 CFU/m^2. And the average concentrations order of microbes in different function area of Meizhou City was commercial area 〉 traffic area 〉 hospital area 〉 scenic spot 〉 residence 〉 culture and education area. The proportion of bacterium, fungi and actinomycetes in the airborne microbes concentration was different in different greenspace, their total trend was 53.7% （bacterium） ,34.5% （fungi） and 11.8% （actinomycete）, The main factors affected on the concentration of airborne microbes were structure, temperature and relative humidity of urban greenspace in different function areas of Meizhou in winter and spring. The air quality （microbe pollution） of the most function areas except culture and education area （comparable cleanliness ） reached or overtaken the slight pollution, of which the sampling spot of commercial area（F） and traffic area（E2） were the worst and reached middle pollution. [ Conclusion] Urban greenspace could decrease the amounts of microbes in air effectively ,with obvious inhibitory effects. But the effects were affected by surrounding environments.
