The experimental results showed that Ulmus pumila, Cotinus coggygria and Pinus tabuliformis should be planted more in the northern brown soil hilly areas; the meadow in the central plain should be planted with Amorpha fruticosa, Koelreuteria paniculata and Platycladus orientalis, and the plants should be cross planted with garden ornamental plants; more plants such as Pinus tabuliformis, Koelreuteria paniculata and Ailanthus altissima should be planted in the southern swamp free tidal soil areas, with more ornamental plants such as Vitex negundo var. cannabifoli.
