The Impact of Urbanization on Biodiversity and Its Regulation Countermeasures

Biodiversity is the basis of ecosystem services and the guarantee for survival of human society. The process of urbanization has brought a series of urban population, resources and eco-environment problems, which has a huge impact on urban biodiversity and has seriously restricted the urban sustainable development. So, it is of great significance to strengthen the research on urban biodiversity for maintaining the urban ecosystem health and regional ecological security and promoting urban sustainable development. This paper analyzes the main problems of urban biodiversity, such as the reduction of biological quantity, species specialization, structure simplification, function degradation and so on. The main reasons are the fragmentation of landscape caused by urbanization, the deterioration of urban ecological environment, the interference of human activities on urban organisms, improper management measures and so on. According to the above analysis, this paper puts forward protection and regulation countermeasures for urban biodiversity from the aspects of strengthening basic research, planning, design, restoration and management, so that this paper can provide references for future urban biodiversity protection and management
