rban waterfront green corridor plays an important role in mitigating the urban heat island (UHI) effect, cooling down the
extreme high temperature in summer and adjusting the urban local climate. Especially in the high-density cities, proper
width of water front green corridor can expand the cooling effect of waterfront green corridor as far as possible in limited area.
Former researches have proved that, with the increase of width, the cooled down area by green corridor will expand. However,
the correlations between them are nonlinear. As a consequence, it is necessary to figure the threshold and saturation points
of width of waterfront green corridor in cooling down city area, to efficiently utilize the land in high-density cities so as to
adapt to climate change and adjust local climate. To realize that aim, empirical researches are conducted with the combination
of measurement and modeling simulation. By using microclimate model ENVI-met, 51 scenarios including different widths
and vegetation densities of waterfront green space are simulated, to calculate the threshold and saturation value of width of
waterfront green corridor under different vegetation structures. At the same time, multi-line simulations are made to clarify
the cooling effects of water body, green space and the combination of them both in the complicate situation that water and
vegetation can both generate cooling effect. In additionally, in-situ measuring experiments are taken in Fengling green space
alongside Suzhou river in Shanghai. By comparing the high-precise measuring data and the simulated data, the models are
verified and analyzed to ensure the accuracy of results. The results show that, when the green corridor is arranged next to water
body, the amplitude of cooled down air temperature can be additional combined. However, the range of cooled down area
cannot expanded obviously. When the cooling capacity of waterfront green corridor is equal to that of water body, the benefit
of waterfront green space on expanding cooling area can be observed. When the vegetation density is increasing in waterfront
green corridor, the saturation value of width will turn to be shorter. The results can provide suggestion for the climate-adaptive
design and planning of waterfront green corridor under the climate change and provide reference for the further research in
the effect of green space on adjusting the urban climate.
