The Influence of Block Morphology Parameters on the Block Microenvironment: A Case Study of Xinjiekou District in Nanjing

Abstract

Urban block is the outdoor living space with high concentration of urban residents, and a good microenvironment of the block is the precondition to improve people's outdoor comfort. In order to comprehensively evaluate the influence of block morphological parameters on the block microenvironment, four typical blocks of Xinjiekou, Nanjing were selected to carry out simulation calculation with the microclimate simulation software ENVI-met. The results show that the block shape parameters represented by plot ratio, greening rate and aspect ratio have a significant impact on the thermal micro-environment of the block. The blocks with high plot ratio, high greening rate and high aspect ratio have better thermal micro-environment.
