Abstract: |
In southern China, plenty of watercourse development projects have been
implemented to improve qualities of urban life and social diversity, which results in rapidly
increase of population and human activities. In response to context of global climate change,
this paper pays attention to effect of watercourse on urban microclimate, specifically studies
methods of maximizing adaptations on dense microclimates, and then discusses urban
design evaluation methodology and strategy based on improvement of body comfort. Taking
Guangzhou Lichi Bay Refine Project (Phase I) as case study, this paper comprehensively
integrates effects from multiple mechanisms, namely prevailing winds, natural convection and
thermal radiation. Microclimate simulation software has been applied to compare the wind
environment and human comfort before and after refinement in order to draw conclusions of
necessity to establish evaluation system of climate adaptability and strategy. Furthermore,
from perspective of human comfort, the paper attempts to optimize modes of operational
urban design and strategy for southern China watercourse space that refers to quantization and
