[Objective] The suitability of the plant community configuration and landscape effect of green low impact development (LID) bio-retention facilities in buildings and residential areas was evaluated to provide a practical reference for the landscape application of bio-retention facility plant communities in Beijing City.[Methods] The bio-retention facilities of the sponge city pilot at Tongzhou District, Beijing City, were examined as the research object based on expert consultation and a field vegetation survey. The analytic hierarchy process was used to propose the factors for the evaluation of the plant landscape in bio-retention facilities, and the system was constructed from three criteria layers and 10 index layers. This model was used to evaluate the plant suitability of 45 samples of 15 biological retention measures.[Results] The biodiversity was a key indicator for the evaluation of plant landscapes in bio-retention facilities. Among the five sponge city pilots, the Simpson diversity of herbaceous plants, and the Shannon-Wiener diversity and Pielou evenness index were the higher for the Bobo pilot, with diversity indexes of 2.09, 0.86, and 0.87, respectively. The plant community landscape of the biological retention facilities in Tongzhou sponge city pilot area was at a high level. The plant landscape for five biological retention facilities was grade I, whereas four, five, and one were of grade Ⅱ, Ⅲ and Ⅳ, which accounted for 33.3%, 26.7%, 33.3% and 6.7% of the evaluation units, respectively. The plants with good evaluation effects and high suitability for practical applications included Hosta plantaginea, Lythrum salicaria, Hylotelephium erythrostictum, and Pennisetum alopecuroides. The plants with a high frequency in a seasonal landscape included Iris tectorum, Hylotelephium erythrostictum, and Symphyotrichum novi-belgii.[Conclusion] In the plant community configuration, it is necessary to pay attention to matching the LID facilities and plant configuration functions, and the development and utilization of native plants to construct the plant community. The plant hierarchy and plant morphology, and ways to increase the diversity of the plant landscape in different seasons, should also be considered.
