树木越来越多地种植在城市的铺砌环境中。然而，很少有人知道树木的生长反应，不同的路面。在这项研究中，三个流行的城市森林树种，松（油松卡尔。），在不同铺筑和未铺筑的地块（透水砖铺筑、不透水砖铺筑和未铺筑作为对照）上以三种不同的间距（0.5 m × 0.5 m、1.0 m × 1.0 m和2.0 m × 2.0 m）种植白蜡（Fraxinuschinensis）和枫树（AtertruncatumBunge）。结果表明，路面显着增加表面温度，改变土壤水分，并降低枫树的成活率，以及所有三个物种的高度和基径增量，除了在0.5 m × 0.5 m的间距灰。铺装层和间距对树高和地径生长量有显著的交互作用。线性回归分析表明，增加表面温度是减少树木的生存和生长的主要贡献者。因此，缓解路面引起的地表温度升高对保证树木的存活和生长至关重要。(C)2017爱思唯尔B.V.保留所有权利。
Trees are increasingly planted within paved environments in cities. However, little is known regarding growth responses of trees to different pavements. In this study, three popular urban forest tree species, pine (Pinus tabuliformis Carr.), ash (Fraxinus chinensis), and maple (Ater truncatum Bunge), were planted on different paved and unpaved plots (pervious brick pavement, impervious brick pavement, and no pavement as the control) at three different spacing (0.5 m x 0.5 m, 1.0 m x 1.0 m, and 2.0 m x 2.0 m apart). Results showed that pavement significantly increased surface temperature, changed soil moisture, and decreased survival rate of maple, and height and basal diameter increments of all three species, except for ash at the 0.5 m x 0.5 m spacing. There were significant interactions between pavement and spacing on tree height and basal diameter increments. Linear regression analysis showed that increased surface temperature was the primary contributor to decreased tree survival and growth. Therefore, alleviating the increased surface temperature induced by the pavement is important for guaranteeing tree survival and growth. (C) 2017 Elsevier B.V. All rights reserved.
