• Mixed diversity of spontaneous and landscape plants in urban linear informal green spaces: adaptive configuration patterns and functional evaluation (2026) · Frontiers in Environmental Science · doi

  the into habitat configuration resources, maintaining The significance of this study lies in revealing the important value of plant diversity in urban linear informal spaces and exploring plant strategies based on plant diversity characteristics. The study systematically incorporates IGS plant framework of urban biodiversity configuration conservation and ecological network construction, emphasizing that the mixed planting of self grown plants and garden plants is not only for landscape purposes, but directly contributes to the stability and resilience of the overall urban ecosystem through providing population communication, and enhancing habitat connectivity. The study provides a scientific basis for optimizing urban green space layout and enhancing green space ecological service efficiency by evaluating the functions of different plants in air purification, spatial organization, and other aspects. By evaluating the aesthetic value of plants, a reference for plant configuration patterns is provided for urban greening and beautification, which helps to create urban landscapes with regional characteristics, enhance urban image and residents’ quality of life. For the improvement of IGS in urban planning, a classified plant configuration strategy should be established; The urban management department can formulate the “Technical Guidelines for Plant Configuration of Urban Linear Informal Green Spaces”, clarify the plant selection list, configuration ratio, and maintenance standards for different types of IGS, and promote the transformation of IGS from a “spontaneous state” to a “standardized guidance”. In highaltitude or subtropical cities with climate conditions similar to Kunming, the indicator system and weight structure of this study can be directly referenced; When applying, special attention should be paid to the localization adjustment of the “ecological adaptation and functionality” dimension. in order Looking ahead, we will further explore the node and corridor functions of different types of IGS in regional ecological networks, the differences and commonalities of plant focusing on configuration patterns in different climate zones and urban scales, to construct a more comprehensive and systematic theoretical system of plant configuration. Meanwhile, we fully recognize that Kunming, as a biodiversity hotspot, boasts plant resources that extend far beyond the scope covered by the current recommended list of landscape plants.

• Herbaceous Plants as a Phytoremediation Tool in Urban Areas: A Review (2026) · Plants · doi

  The paper identifies a gap in the use of herbaceous plants for phytoremediation in urban areas. It highlights the need for strategic planning to expand and improve urban green spaces. The paper notes that prior work has focused on the potential of herbaceous plants, but a systematic examination of their phytoremediation capabilities is lacking.

• Multi-layered Urban Forests: can a City be dense and green? (2026) · Frontiers in Sustainable Cities · doi

  The paper identifies a gap in current greening practices, which tend to support more ubiquitous or cosmopolitan urban species. The paper argues that remnant green space habitats support more unique biodiversity, such as rare and threatened species. The paper identifies a need to distinguish between remnant green spaces and designed green spaces.
