Study on Plant Landscape of Beijing Urban Linear Parks Based on Bird Diversity Improvement

Urban linear parks of high vegetation coverage can be used as migration routes and habitats of birds. As a part of the ecological corridors, they also contribute to the protection of bird diversity with the construction of suitable plant landscape and the promotion of plant species. Therefore, this paper studies the green space of Beijing urban linear parks with the standard sampling method, to extract the plant community factors and plant habitat factors that may affect bird diversity, and provides constructive advice on improving bird diversity. The main results of the research show that in linear parks with a span of 30~200m green space, with the width of green space increasing, the number of birds will rise. Urban linear parks with different types of plant habitats have various attractions to different species of bird target species. The linear parks with more kinds of plant habitats have higher attractions to bird target species. Different species of bird target species tend to prefer different species of trees.
