IMPACTS OF URBAN EVOLUTION ON BIODIVERSITY CONSIDERING THE SUSTAINABLE DEVELOPMENT OF THE ECOSYSTEM

The life of urban residents demands sufficient material supply and a good eco-environment. The rapid expansion of cities has stimulated the urban population and economy, exerting irreversible changes on the eco-system. During the urban evolution, it is of great importance to evaluate the overall impacts of urban development on biodiversity. The evaluation aims to integrate biodiversity protection into urban development and maintain it in a harmonious and stable state. Focusing on ecosystem sustainability, this paper designs the architecture to evaluate the impacts of urban evolution on plant diversity, and creates an integrated evaluation system for biodiversity from five perspectives, namely, species richness, species diversity, species evenness, species importance and population diversity. On this basis, the proposed system was applied to assess the biodiversity in a city. The assessment results show that continuous biodiversity evaluations can ensure the sustainable development of species during urban evolution. The research findings provide new insights into the diversity and sustainability of urban species.
