Research on Landscape Design Approach ofSpontaneous Community: Exploration on theImprovement Design of Urban Spontaneous GroundCover Plant Community Based on CSR Theory |

Abstract: |
The spontaneous community in the urban environment
is considered as a vegetation resource with extensive ecological
service functions, but it is difficult to be used in the process of urban
construction. After landscape architecture design, the spontaneous
community will have clearer community structure and aesthetic
characteristics, and will also have the value of green space design
practice. In the face of complex community composition, difficulty
in plant screening, lack of stability and aesthetic characteristics
and other issues, based on the idea of improvement design of
spontaneous groundcover plant community, this study proposes a
design approach that relies on the CSR theory to regulate the species
composition, vertical structure and landscape characteristics of the
spontaneous community, and adopts low interference management.
The competition and succession of the community were promoted
after the intervention, and finally formed a stable groundcover plant
community. A preliminary experiment was conducted to validate
the idea. After 3 years of succession, the species composition of
the experimental community shifted from R-selection dominance
to C-selection dominance, and the plant density and coverage of
the experimental community significantly increased. The structure
of the experimental community includes the main landscape
layer, bottom space protection layer, and decorative landscape
layer, exhibiting unique plant landscapes at different times. The
experimental results verify the feasibility of the approach of
improvement design of urban spontaneous plant community, and
provide a reference for ecological design of urban plant landscape. |
