Investigation of Species and Application of Color-Leafed Plants in Shanghai

Color-leafed plants played an important role in urban landscapes because of their special decoration effects to environment. We investigated the species and application of the color-leafed plants planted in the arterial roads, parks, public green spaces, residential districts and schools in municipal districts of Shanghai. The result showed that about 45 species or varieties of color-leafed plants had been applied in Shanghai and the majority of them were trees or shrubs. Including Prunua cerasifera cv. Atrupurpurea, Loropetalum chinense vat. rubrum, Liguatrum x Vicoryi and Berberis thunbergii, which were the most common color-leafed plants employed in garden construction in Shanghai city. From our investigation, the color-leafed plants had been applied in every district of Shanghai, while the area of application was limited and the application forms were relatively monotonous. They were usually planted in isolated grasslands as parterre or hedgerow and in lawns of parks through the form of group, massive or stroll planting. On the basis of investigation and analysis, we raised the application proposal of color-leafed plants in Shanghai in the future.
