摘要:探究不同面积灌草型植物群落对城市降温增湿的影响,对提升城市园林绿地的生态功能具有重要的意义。本文在南京选取8个不同面积的灌草型植物群落作为研究对象,利用温湿度记录仪对其进行温湿度测定,分别研究绿地规模、绿量与降温增湿的关系。结果表明,不同群落的降温增湿效果存在着明显的差异。本文的研究结果如下:(1)灌草型植物群落降温效果小型>中型>大型,增湿效果中型>小型>大型。(2)外界温度越高,灌草型植物群落降温增湿效果越显著;球灌草型植物群落降温增湿效果优于绿篱灌草型。(3)草本绿量与灌草型植物群落降温效果呈显著的负相关关系,对增湿效果影响不大;灌草绿量比对植物群落降温效果影响不大,与增湿效果呈高度正相关关系。25662

The cooling and humidification effect of shrub - grass type plant communities with different area in Summer
Abstract: It is of great significance to explore the effect of shrub grass plant communities on urban cooling and humidification, and to enhance the ecological function of urban green space. In this paper, eight different shrub-type plant communities in Nanjing were selected as the research object. The temperature and humidity were measured by temperature and humidity recorder. The relationship between green scale, green quantity and cooling and humidification was studied. The results showed that there were significant differences in the effect of cooling and humidification in different communities. The results of this study are as follows: (1) shrub-type plant community cooling effect of small> medium> large, moisturizing effect medium> small> large. (2) The higher the outside temperature, the more obvious the effect of cooling and humidification of the shrub-type plant community; the effect of cooling and moistening effect of the shrub-grass type plant community was better than that of the hedgerow type. (3)There was a significant negative correlation between the green amount of herbaceous grass and the cooling effect of shrub-based plant community, and had little effect on the humidification effect. The shrub / green ratio had little effect on the cooling effect of plant community and was positively correlated with the humidification effect relationship. 源¥自%六^^维*论-文+网=www.lwfree.cn
