Abstract:

Herbaceous spontaneous plants can grow spontaneously in urban environments, which not only reduces maintenance and management costs, but also significantly enhances urban biodiversity. To explore the potential application of herbaceous spontaneous plants in urban greening, the article took landscape preference theory as the research basis, and uses habitat type, plant ornamental characteristics, and combination elements as factors for photo simulation. Questionnaire survey and field investigation were used, combined with on-site interview results for analysis. The research results indicated that there were a total of 212 species in 176 genera and 60 families of herbaceous autotrophic plants. After the introduction of herbaceous autotrophic plants, the overall popularity of the public had increased; Among the habitat types of herbaceous autotrophic plants, waterfront lawns had the highest preference; The preference for flowering species was the highest among plant species. By using appropriate design techniques, the preference for spontaneous foliage plants could be effectively enhanced; The aesthetic preferences of herbaceous plants were largely related to the social attributes of the public themselves. More ornamental species should be preserved in maintenance and management; The most suitable application scenario for herbaceous self growing plants was in forest grasslands; Control the height of leaf autotrophic plants below 30 cm; Foliage plants higher than 60 cm should be kept in the forest grassland; Enriching the species composition of autotrophic plant communities to achieve maximum ecological benefits. The conclusions and suggestions of this article can provide effective guidance for the promotion and application of herbaceous spontaneous plants, and provide reference for the future application practice of herbaceous spontaneous plants in urban greening.
