英文摘要	Two common urban greening trees, ash (Fraxinus chinensis Roxb.) and maple (Acer truncatum Bunge.), were planted in arranged pervious and impervious land pavements to clarify the response in the photosynthetic processes of the urban tree under different types of pavement. Leaf light and CO2 response curves of the net photosynthetic rate were constructed based on in situ measurements in the 4th year after planting, and additional photosynthetic parameters were obtained. The surface temperature and soil temperature significantly increased while the soil moisture significantly decreased in the land pavement, and these changes varied with types of pavement. The light-saturated net photosynthetic rates of both ash and maple, the saturated intercellular CO2 concentration of ash, and the light saturation point, CO2-saturated net photosynthetic rate and maximum carboxylation rate of maple significantly decreased in impervious pavement, indicating that both the capacity of leaf photosynthesis and utilization of high light and CO2 concentrations were significantly reduced by land pavement. The down-regulation of photosynthesis in the impervious pavement was mainly due to the reduction of available soil water. Photosynthetic parameters of maple showed more sensitivity to the land pavement than those of ash. There was less impact from pervious pavement than impervious pavement on the photosynthetic parameters of ash and maple.
