The assessment of the green sustainability of landscapes is currently the focus of research. This article uses a new ecological assessment -emergy method to evaluate quantitatively the ecological sustainability of Nanjing Green Expo Park. The results show that the non-renewable energy value of the main plant occupies a major position, which is much higher than the amount of renewable energy. Among 18 species of plants, tulips and citrons have absolutely more energy. The values of sustainability are: ELR=289; NEYR=2.01; ESI=0.007. The results indicate that the overall environmental loading capacity of the Green Expo Park is large, the net energy production is low, and the degree of sustainable development is extremely unreasonable. Based on emergy theory, this paper discusses the sustainability assessment of the Green Expo landscape and provides a new idea for the sustainability assessment of landscapes.
