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.
