| Abstract: |
| With the development of urbanization in China, the
negative impact of urban heat island effect is growing. The summer
high temperature in urban areas affects the health and comfort of
residents. Previous studies have shown that urban park green space
can effectively alleviate the urban heat island effect in summer.
In this study, nine different parks in Suzhou Industrial Park were
selected as the research objects. The under-laying surface and
characterization factors of each park, including perimeter area ratio,
perimeter, area, shape index, fractal dimension, canopy density,
green space ratio, composition ratio of underlying surface and
distance from lake, were observed and analyzed. The results show
that the water area coverage rate has the most significant positive
correlation with the cooling and humidifying effect of the park,
and it has the largest contribution to the cooling and humidifying
effect of the park. The perimeter area ratio of the park has the most
significant negative correlation with its cooling and humidifying
effect, and the park area has the most significant positive correlation
with its cooling and humidifying effect. The perimeter area ratio of
the park has the greatest contribution to its cooling and humidifying
effect. The characterization factors of the park and the distance from
the lake can account for 69.7% of the cooling effect and 79.4% of
the humidification effect. |
