Abstract: Birds, as an important component of urban biodiversity and an indicator species for the health of urban ecosystems, are critical for improving urban human well-being. With the rapid development of urbanization, the bird habitats were destroyed and the number of birds were decreased, which even threatened the sustainable development of human society. Urban parks become the last shelter for urban birds. Therefore, the research on the impact of plant communities in urban parks on bird diversity is the key issue in current research on biodiversity conservation. This study reviewed the impact of park plant communities on bird diversity from five aspects: vegetation patch area, plant community type, plant community composition, plant community structure and vegetation coverage, in order to provide reference for future research on the influence of park plant communities on bird diversity, and provide specific measures and new ideas for the future urban construction of park vegetation construction based on bird attraction and bird protection.
