Microclimatic spatial planning for Xianghe Segment of China’s Grand Canal

ABSTRACT With the emerging problems of air pollution and urban heat island associated with urbanization, urban microclimatic spatial planning was attended unprecedentedly. Microclimatic spatial planning is proposed within the framework of landsenses ecology and its aim is to harmoniously integrate human with nature and specifically to improve the microclimate comfortable sensation for people from wind speed, temperature, humidity, etc. In this paper, we analyzed the current spatial pattern of the microclimate in Xianghe Segment of China’s Grand Canal (XSCGC) based on meteorological data, and a computational fluid dynamics (CFD) simulation of human comfort and microclimate expandability. Finally, spatial planning recommendations for XSCGC were proposed to suppress northeasterly winds and protect southwesterly winds, which helped divide the planning area into four functional land-use types to improve the livability and security of microclimate, including microclimate regulatory areas, development core areas, natural ventilation corridors areas, and development extension areas.
