摘　　要：生态系统服务功能已成为生态学研究的热点,但水库生态系统服务功能的研究较少。对深圳市梅林水库和西丽水库调节小气候和净化空气细菌的服务功能进行了实地研究,并对调节小气候的服务功能进行了价值评估。结果表明水库生态系统有一定的降温、增湿和净化空气细菌效应。在炎热的夏季,梅林水库和西丽水库的平均温度和最高温度比市区分别降低1.59、2.35℃和2.56、4.10℃。在干燥的冬季,梅林水库和西丽水库相对湿度的平均值和最大值较市区分别提高了6.01%、11.10%和7.38%、7.80%。梅林水库、西丽水库和市区空气细菌数量分别为9、10 cfu/皿.5m in和107 cfu皿/.5m in,库区空气细菌数量远远少于市区。梅林水库和西丽水库调节小气候的服务价值分别为1249.13×104元.a-1和5441.83×104元.a-1。Ecosystem services are a hot spot in modern ecological research, but few studies on reservoir ecosystem services have been conducted. Microclimate regulation and airborne bacteria purification were investigated in Meilin Reservoir and Xili Reservoir, Shenzhen, China. Results showed that reservoir ecosystems may help lower air temperature, increase humidity and purify airborne bacteria. In summer, the mean and maximum air temperatures in Meilin Reservoir and Xili Reservoir were 1.59℃, compared with the urban 2.35℃ and 2.56℃, 4. 10℃ lower than those in the urban area, respectively. In winter, area, the mean and maximum relative humility in Meilin Reservoir and Xili Reservoir increased by 6.01% , 11. 10% and 7.38% , 7.80% , respectively. The number of airborne bacteria （9 and 10 cfu/plate 5min） in Meilin Reservoir, Xili Reservoir was considerably lower than that （ 107 cfu/plate 5min） in the urban area. The values of microclimate regulation service in Meilin Reservoir and Xili Reservoir were estimated as 1249. 13×10^4 yuan a^-1 and 5441.83 × 10^4 yuan a^-1, respectively.
