基于提高鸟类多样性的北京城市线性公园绿地植物景观探析

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

植被覆盖率高的线性公园,可作为鸟类的迁徙途径和栖息之所,并猜测其可作为生态廊道的一部分,适宜的营造植物景观、提升植物种类的多样性对保护鸟类多样性有促进作用。因此,采用标准取样法对北京城市线性公园绿地进行研究,提取可能影响鸟类多样性的植物群落因素、植物生境因素,对提高鸟类多样性提出建设性的意见。研究结果主要表明,在线性公园绿地宽度30～200m内,随着宽度的增加,鸟类的数量有所提高;含有不同类型植物生境的线性公园绿地,对鸟类目标种的吸引力不同,植物生境类型数较多样的线性公园绿地具有较高的鸟类目标种吸引力;不同的鸟类目标种偏好在不同的树种上进行活动。

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.
