| Abstract: |
| As the transition section between urban residential areas
and natural agricultural areas, urban country parks play an important
role in the absorption and transmission of urban carbon dioxide.
The design of the internal green space structure of the country park
plays a key role in its carbon neutralization function. Based on the
exertion of the carbon sink function of the country park, this study
focuses on the different effects of its green space edge space and
internal space on the carbon dioxide accumulation, transmission and
absorption. The study constructs green space samples of three types
called "carbon capture area, carbon circulation area, and carbon
absorption area" based on the basic landscape elements of "corridors
and patches" in landscape ecology. CFD fluid simulation software
is used to simulate and compare the changes of wind environment
and carbon environment under 9 typical modes, and the optimal
quadrat mode under different carbon functions is selected. With the
second green belt of Beijing as an example, the coupling application
relationship between the form of "corridors and patches" in the
sample area and the park landscape elements is analyzed, and the
construction approach of the internal green space structure layout of
the country park under the guidance of carbon sink is preliminarily
explored. |
