Abstract: Under the concept of neo-naturalism, herbaceous plant community plays an increasingly more important role in the construction of ecological smart cities and urban quasi-natural landscape because of the remarkable advantages of low maintenance and long cycle. Therefore, it is urgent to explore innovative methods of spatial design of herbal plant community under the concept of ecological planting in order to guide the construction of urban quasi-natural landscape. This paper reviews cases on planting space design of typical herbaceous plant communities under the concept of neo-naturalism planting, summarizes the role of each type of herbaceous plants in community spatial design. Taking four stable herbaceous plant combinations in our ecological herbaceous experimental base as examples, the paper summarizes the spatial design patterns of four herbaceous plant communities, which are expected to contribute to the application of the ecological planting paradigm of new herbal plant community to the construction of urban quasi-natural landscape space in the future.
