"Cold Bridge" Reconstruction to Optimize Megalopolis' Self-Regulative Thermal Climate Environment

Abstract

Atmospheric underlying surface change is the main reason for urban heat island and fog and haze. According to constructing a network-like cold bridge as well as coordinating the layout of urban hard underlying surface and soft underlying surface which can promote urban wind-heat movement, urban thermal climate environment may be improved by diffusing heat and solids effectively. As to suzhou, both city regional natural ecological pattern and main urban areal natural ecological environment structure reflect this philosophy.
