| Abstract: |
| Urban green space plays an important role in improving the
quality of urban living environment and maintaining the public health
of residents. Negative air ion (NAI) is one of the basic parameters to
evaluate urban air cleanliness. Taking the urban green space of Beijing
Olympic Forest Park (BOFP) as an example, this research selects the
typical plant community structure, type and landscape environment
test sample points, and analyzes and explains the spatial differentiation
characteristics of NAI in BOFP based on the continuous dynamic
measurement data for 15 years. The results showed that the concentration
of NAI in different plant community structure areas of BOFP was
MPC>DPC>SPC; TG>TS>SG; the concentration of NAI in different
plant communities was DBP>CP>G>CBP>S; that in different landscape
environments was as follows: WPC>MPC/SPC>WS; and there was a
significant correlation between NAI, CD, and LAI. This research results
provide the basically scientific basis for the planning, design, renewal
and optimization of functional urban green space based on "evidencebased design". |
