摘要：Urban heat island effect is much prevailing nowadays with cities expanding. Park cooling island (PCI) is critical to mitigate this effect. Although the cooling effects of greenspace have been known well, the understanding on the roles of landscape inside and outside parks in PCI intensity is still obscure. In this study, we selected PCI range (L-Delta max), amplitude of temperature difference (Delta T-m(ax)) and temperature gradient (G(temp)) to evaluate PCI intensity and explored their relationships with landscape patterns using correlation analysis and stepwise regression model. Results showed that 218 out of 266 parks served as the local cooling island, with average L-Delta(max) of 313 m, Delta T-m(ax) of 1.71 degrees C and G(temp )of 0.74 degrees C/hm. Compared to those without PCI, these parks were larger and more compact, and had more but less fragmented tree canopy, and less coverage of impervious surface. Correlation analysis and stepwise regression models showed that L-Delta(max) was largely regulated by the landscape outside the parks, while Delta T(max)( )was to less degree controlled by the landscape patterns. G(temp) was largely determined by L-Delta(max). It is indicated that the distinguishing programs should be established for different purposes, which will provide useful implications for urban park design.
