[Objective] Aim to reveal the growth patterns of 4 street tree species and how they adapt to the change of relationship between soil structure, nutrient and water condition. And to explore the management model of soil structure and nutrients suitable for the street trees in Shanghai, so as to improve their growth in Shanghai. [Method] Planting substrate experiments were carried out by orthogonal design with three factors of soil content diameter, the proportion of structure soil and soil moisture, each in four levels. The growth of aboveground parts and the root expanding of these trees under different conditions were analyzed. [Result] The results showed that the planting substrate had significantly influences on the height of Platanus orientalis. The height in treatment 3 was 4.42 m and significant higher (11.90%) than that of the control group. In addition, different treatments significantly influenced the tree's root expanding and biomass accumulation. The results indicated that the most suitable conditio
