| 中文摘要: |
| 以长沙市13种常用灌木树种为对象，对灌木树种蒸腾作用速率进行测定，研究灌木树种降温增湿效应。结果表明：同种灌木树种降温增湿量表现出6月较大的有7种，表现出8月较大的有5种，表现出10月较大的仅1种。不同灌木树种在同一月份的降温增湿量，4月以小叶女贞最强，6月、8月和10月均以紫荆最强。灌木树种单位叶面积年平均降温增湿效应表现为紫荆＞红叶石楠＞小叶女贞＞海桐＞木槿＞火棘＞红继木＞石榴＞杜鹃＞腊梅＞山茶＞大叶黄杨＞四季桂。利用统计分析软件，得出灌木树种降温增湿效应最好的是红叶石楠、小叶女贞、紫荆，其次是海桐、木槿、火棘、红继木、石榴，再次是大叶黄杨、山茶、四季桂、腊梅、杜鹃。 |
| 英文摘要: |
| The 13 familiar shrub species in Changsha city were chosen as research object. It has tested the transpiration rate of the shrub species and research on the temperature decrease and humidity increase effect of the species. The results showed that: the same shrub species of temperature decrease and humidity amount exhibited that 7 species were larger in June and 5 species larger in August and only one species larger in October. Different shrub species of temperaturedecrease and humidity increase amount in the same month exhibited that the strongest species in April is Ligustrum quihoui Carr and the strongest species in June, August and October are Cercis chinensis Bunge. Verage annual temperature decreasing and humidity increasing amounts per leaf area of shrub species sort is: Cercis chinensis Bunge跃Photinia serrulata＞Ligustrum quihoui Carr＞Pittosporum tobira＞H. Syriacus＞Pyracantha fortuneana＞Lorpetalum chinense var rubrum＞Punica granatum＞Rhododendron simsii＞Chimonanthus praecox＞Camellia japomica＞Euonymus japonicus跃Osmanthus fragrans var. Semperflorens. Using cluster analysis, a comprehensive evaluation is made to give a ranking list. Among shrub species, Photinia serrulata, Ligustrumquihoui Carr, Cercis chinensis Bunge get the best of temperature decrease and humidity increase effect, while Pittosporum tobira, H. Syriacus, Pyracantha fortuneana, Lorpetalum chinense var. rubrum, Punica granatum, get a medium of it, and Euonymus japonicus, Camellia japomica, Osmanthus fragrans var. Semperflorens get minimum of it. |
