Urban Forest Construction and Vertical Greening Development Under Climate Change

Abstract

In high-density cities, relatively large area of buildings may accommodate increasing volumes of vertical greening, which will effectively help alleviate global climate change. This article emphasizes that landscape architects and constructors should refresh their understanding of urban forests and realize the role of vertical greening as its vital component. Although current practices of vertical greening are restricted by climatic environment, advances of technology and innovation of materials will provide new opportunities for the development of urban forests. For example, by utilizing a novel type of substrate, “base soil,” we can get rid of conventional vertical greening technologies that usually rely on pot-planting and frequent replacement, while enjoying more ecological benefits. This article also suggests employing prefabricated greening technologies to meet the ever-increasing demands of urban forests; establishing a systematic cost-benefit assessment system on vertical greening to measure the ecological, social, and economic values; and encouraging citizens to take a more active part in vertical greening practices by making them aware of environmental and social benefits brought by urban forests.
