With the accelerating of urbanization, land pavement has been expanding rapidly in cities worldwide, leaving the limited space available for urban trees. Many trees have to be planted next to or within paved land. Land pavement prevents the exchanges of water, air, nutrient, and heat between soils and other environmental compartment, and changes the microclimate of urban trees, thus significantly influences the growth of urban trees. The spacing of trees will result in plant competition for light, water and nutrients and it is also an important factor which can affect the growth of urban trees. In this study, three urban tree species, including pine (Pinus tabilaeformis Carr.), ash (Fraxinus chinensis Roxb.), and maple (Acer truncatum Bunge.), were planted on different pavement types (impervious brick pavement, pervious brick pavement, and no pavement as the control) at three different spacings, including low (0.5 m×0.5 m apart), middle (1.0 m×1.0 m), and high (2.0 m×2.0 m). After 6 years of growing, the basal diameter, height, individual biomass, and its allocation of the three tree species were investigated. Compared with the control, the height of pine, ash, and maple under impervious pavement significantly (P<0.05) decreased 13.5%-23.9%, -4.6%-20.9%, and 15.5%-22.1%, respectively. The individual biomass of ash and maple under impervious pavement also significantly (P<0.05) decreased 2.1%-27.1% and 33.6%-52.3%. While the root to shoot ratio (R:S ratio) of ash and maple under impervious pavement significantly (P<0.05) increased 3.4%-25.8% and 15.7%-23.4%. Relative to impervious pavement, the height of ash and maple under pervious pavement significantly (P<0.05) increased 11.6%-37.0% and 11.2%-26.2%. The individual biomass of ash under pervious pavement significantly (P<0.05) increased 5.3%-45.5%, R:S ratio significantly (P<0.05) decreased 11.4%-18.7%. The basal diameter and individual biomass of the three tree species were inhibited with the increase of spacing. While there was no significant difference on biomass per area between low and middle spacing for the three tree species. In addition, there was no significant interactions between pavement and spacing inhibition of basal diameter, height, individual biomass, and R:S ratio in the three urban tree species. Therefore, pervious materials are more suitable for land pavement where trees will be planted. Ash showed more tolerance to land pavement than maple, indicating that the selection of tolerant tree species is essential for urban planting. The rational close planting is also an important factor to ensure the growth of urban trees.
