Abstract: The rain garden, which is represented by the low-impact development model, is a green “sponge” constructed in a sponge city. In view of the climate adaptability of plants, this research focused on the selection and allocation of plants and recorded the undergrowth plant landscape in plant configuration of rain garden by the methods of field survey and data analysis. Analytic hierarchy process was used to evaluate the distribution effect of undergrowth plants in the garden. The result showed that the commonly used plants in rain gardens in Gongkang Rain water Garden were mainly drought-tolerant and had well-developed roots. The main plant species were as follows: trees, such as Metasequoia glyptostroboides, Salix babylonica, Paulownia tomentosa, Acer palmatum ‘Atropurpureum’; shrub species, such as Fatsia japonica, Aucuba japonica ‘Variegata’, Loropetalum chinense; herbs, such as Hemerocallis fulva, Farfugium japonicum, Stipa tenuissima; aquatic plants, such as Phragmites australis, Gladiolus× gandavensis, Iris pseudacorus, Iris tectorum, Lythrum salicaria, Cyperus alternifolius. According to the growth area and ornamental characteristics of plant, plant species and distribution pattern of undergrowth plants with good landscape effect were selected as follows: mode A, Iris pseudacorus+Thalia dealbata+Lythrum salicaria+ Phalaris arundinacea+ Typha orientalis+ Iris germanica; mode B, Lythrum salicaria+ Cordyline fruticosa+ Iris tectorum+ Cyperus alternifolius+ Thalia dealbata+ Gladiolus × gandavensis+ Juncus setchuensis; mode C, Cyperus alternifolius+ Iris germanica+ Iris tectorum+ Cordyline fruticosa+Hemerocallis fulva+Thalia dealbata+Iris pseudacorus.

Key words: rain garden, plant selection, undergrowth plant configuration, analytic hierarchy process
