Study on the Application of Shade-tolerant Ground-cover Plants in the Green Space of Park in Guangdong Region

【Objective】The application of plants in different canopy closure was researched to provide references for the landscape construction of special ground-cover plants.【Method】Taking the ground-cover plants in the park green space of Guangzhou and Shenzhen as the research objects, the green space with better undergrowth vegetation landscape was randomly selected as the plot. By measuring the canopy closure under the forest, the suitable species, constitutive features and configuration characteristics of ground-cover plants under different canopy closure environments were analyzed.【Result】 A total of 92 species（varieties）of shade-tolerant ground cover plants were recorded, of which most species belong to the family Asparagaceae, Marantaceae, and Araceae. Forty-three species had high shade tolerance, which were suitable for growing under forests with a canopy closure more than 0.9, and 31 species of ground-cover plants had a wide range of adaptation to the illumination. Most flowering plants had good flowering performance in the forest space with the canopy closure less than 0.8. The application of ground-cover color leaf plants could make up for the lack of color of the landscape under the forest. The patterns of plant configuration under the forest were mainly based on flat planting, column planting, band planting and natural configuration, and it should be rationally selected according to the characteristics of the landscape and the theme of the park layout.【Conclusion】The regional park green space of Guangdong is rich in shade-tolerant ground-cover plants, and the plants are mainly in natural configuration pattern.
