Study on Ecological Structure and Landscape Optimization of Urban Landscape Plant Community Based on 3d Virtual Technology

Abstract

Urban gardens are artificial ecosystems, and whether their functional systems can achieve a virtuous cycle depends on the stability of artificial plant communities. Compared with nature, the resources and space in the city are very limited, and every living thing in the garden needs a certain amount of space and resources. Therefore, when constructing the ecological garden plant community, it is necessary to determine the species of dominant tree species and associated tree species in the community according to the niche principle. Plant community directly determines the structure and function of green space. Therefore, people pay more and more attention to whether the selection and application of urban greening tree species are scientific and reasonable, and how to change the traditional plant configuration without considering the defects of community structure and functional characteristics. Based on three-dimensional virtual technology, combined with seasonal changes of plants, this paper creates space-time artistic conception, creates suitable landscape features according to different functional requirements, and utilizes suitable silviculture measures to control community succession, optimize the landscape structure of plant communities, and construct an urban landscape with optimized structure, powerful functions and beautification.
