Research on the relationship between the structural types of urban belt green space in arid areas and its temperature-humidity effects
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.
