摘  要:利用小尺度定量测定的方法,选择南疆干旱区城市新疆生产建设兵团阿拉尔市青松路东侧4种内部结构、5种郁闭度绿地(宽度45 m)作为研究对象,研究夏季干旱区绿地结构类型与温湿效应的关系。结果表明:1)4种内部结构绿地降温增湿效应强弱为:乔-灌-草>乔-草>灌-草>草坪;与对照相比,草坪降温增湿效应不显著(P>0.05),乔-灌-草与灌-草、草坪之间降温增湿效应差异性显著(P<0.05);在13:00—17:00之间,乔-草与灌-草、草坪之间的降温增湿效应达到显著水平(P<0.05),乔-草绿地与乔-灌-草温湿效应未达到显著水平(P>0.05);2)5种郁闭度绿地降温增湿效应强弱为:86%>65%>46%>28%>12%;与对照相比,郁闭度65%、86%与28%、12%的绿地间降温增湿效应差异达到显著水平(P<0.05),郁闭度65%与86%的绿地间温湿效应未达到显著水平(P>0.05);3)乔-草与乔-灌-草降温增湿效应显著且趋于稳定,绿地郁闭度达到65%时,降温增湿效应显著且趋于稳定。Using the small scale quantitative measurement method,four kinds of internal structures and five kinds of canopy density green space(45 m width)were selected as the research objects in the east side of Qingsong Road,Alar City in the arid region of southern Xinjiang to study the relationship between the structure type of green space and the temperature and humidity benefit in the summer arid region.The results showed that:1)the efficiency of four kinds of green greenhouses with internal structure was as follows:Tree-Shurb-Herbage>Tree-Herbage>Shurb-Herbage>lawn.Compared with the control,the temperature and humidity effect of the middle lawn was not significant in all periods(P>0.05),and the temperature and humidity benefit between the lawn and Shurb-Herbage reached a significant level and was Tree-Shurb-Herbage(P<0.05).Between 13:00 and 17:00,the temperature and humidity benefits of Tree-Herbage,Shurb-Herbage and lawn reached a significant level(P<0.05),but the temperature and humidity benefits of Tree-Herbage and Tree-Shurb-Herbage did not reach a significant level(P>0.05).2)The temperature and humidity benefits of the five types of greenery with canopy density were as follows:86%>65%>46%>28%>12%;Compared with the control,the temperature and humidity benefit of green space with 12%canopy density was not significant in all periods(P>0.05).The cooling and humidification benefits of green Spaces with canopy density of 65%,86%,28%and 12%reached a significant level(P<0.05),while the temperature and humidity benefits of green Spaces with canopy density of 65%and 86%did not reach a significant level(P>0.05).3)The cooling and humidification effect of arbor-grass and arbor-shrub-grass is significant and tends to be stable.When the canopy density of greenbelt reaches 65%,the cooling and humidification effect is significant and tends to be stable.
