An improved self-circulating and filtering PVC vertical greening device
With the accelerated pace of urbanization,people have witnessed the emergence of various environmental problems such as the urban heat island effect,haze and waterlogging.In the face of these increasing urban problems,people have become more concerned about the environmental quality of urban life,making"forest cities"a hot topic of discussion.Urban greenery is the key to the healthy living environment pursued by urban residents,which not only provides a pleasant ecological atmosphere,but also realizes the harmonious symbiosis between buildings and nature,such as wall greening,riverbank vegetation,interchange green space,balconies,green roofs and indoor plants.At present,in order to solve these problems of ecological environment restoration and urban per capita land constriction,in order to increase the area of urban green space and improve the living space of people,vertical greening has been widely concerned.This paper carries out an improved design and proposes an improved self-circulation and filtration type PVC vertical greening device,which can filter the silt problem brought by plants and soil,improve the plant growth environment,and provide certain reference for the development of vertical greening field.
