夏季不同绿地类型温湿度及空气负离子浓度变化特征研究

选取5种不同树种组成的绿地类型，对其内部空气温度、相对湿度和空气负离子浓度进行定点实时监测，以研究不同绿地类型在调节局地小气候功能方面差异。结果表明，①夏季高温时段杉木林和无患子一国槐混交林的降温效果较为明显，低温时段雷竹林的降温效果最为显著。②夏季高温时段杉木林和乐昌含笑一桂花混交林的增湿效果较为明显，低温时段雷竹林的增湿效果较为突出，与降温效果差异相比，5种绿地的增湿效果差异相对较小。③夏季不同绿地类型的空气负离子浓度差异不十分明显，只有无患子一国槐混交林的负离子浓度水平显著高于其他绿地。④综合相关指数，认为以杉木林为代表的森林型绿地和以无患子一国槐混交林为代表的防护型绿地是夏季对人类较为...

Summary:选取5种不同树种组成的绿地类型，对其内部空气温度、相对湿度和空气负离子浓度进行定点实时监测，以研究不同绿地类型在调节局地小气候功能方面差异。结果表明，①夏季高温时段杉木林和无患子一国槐混交林的降温效果较为明显，低温时段雷竹林的降温效果最为显著。②夏季高温时段杉木林和乐昌含笑一桂花混交林的增湿效果较为明显，低温时段雷竹林的增湿效果较为突出，与降温效果差异相比，5种绿地的增湿效果差异相对较小。③夏季不同绿地类型的空气负离子浓度差异不十分明显，只有无患子一国槐混交林的负离子浓度水平显著高于其他绿地。④综合相关指数，认为以杉木林为代表的森林型绿地和以无患子一国槐混交林为代表的防护型绿地是夏季对人类较为适宜的绿地类型。

This paper mainly chooses 5 different species of trees which made of the greenbelt type. We monitor the inner air temperature, relative humidity and air ions concentration at actual time in certain area so as to study the difference of different greenbelt type in adjusting certain area＇s microclimate. The results demonstrates that： （1） when it is at high temperature time in summer, Cunninghamia lanceolata forest and soapberry Chinese scholartree mixed forest＇ s function of cooling and humidifying is better. Lei bamboo forest has an outstanding effect on humidifying when it is at low temperature. （2） Cunninghamia lanceolata forest and Michelia Chapensis-Osmanthus fragrans mixed forest has a m
