居住区绿化树种固碳释氧和降温增湿效应研究

以青岛市居住区广泛应用的14种植物为材料,利用Li-6400便携式光合测定系统进行了光合生理生态指标的测定.并对其固碳释氧与降温增湿效应进行了量化研究.结果表明:14种植物的固碳释氧量由高到低排列为榆叶梅、悬铃木、绦柳、月季、紫叶桃、火棘、丁香、紫叶李、国槐、海桐、樱花、女贞、金叶女贞、红枫.降温增湿能力由高到低为榆叶梅、悬铃木、绦柳、月季、紫叶桃、火棘、丁香、紫叶李、国槐、海桐、樱花、女贞、金叶女贞、红枫.同时对各树种固碳释氧量的趋势进行了分析,以期为居住区绿化树种的选择与配置提供科学依据.

Study on the Greening Tree Species of Residential Area's Cooling and Humidification and Carbon Fixation and Oxygen Release

This article took fourteen widely used plants in Tingtao as materials,used portable Lci photosynthesis test system to test physiological indices.Furthermore,the carbon fixation and cooling and humidification effects were researched.The results showed:the amounts of carbon fixation and oxygen release of fourteen plants from the highest to the lowest was different,cooling and humidification ability of fourteen plants from the highest to the lowest was,different also.Meanwhile,we had analyzed the trend of the amounts of carbon fixation and oxygen release and gave suggestions on compatability of the plants in order to give scientific foundation on choosing plants and their compatability.
