| 城市化是导致生物多样性波动的主要因素之一。为了探讨城市公园特征参数（如公园面积、林地面积和距市中心距离等）对城市鸟类物种多样性和功能多样性的影响，于2021-04—2021-08，采用样线法对广西柳州12个城市公园进行鸟类监测。利用多元回归和广义线性模型分析公园特征参数对鸟类物种多样性和功能多样性的影响。结果显示：城市公园面积与鸟类物种丰富度呈正相关，鸟类功能多样性RaoQ指数与距离市中心距离呈正相关，鸟类功能均匀度指数与林地面积和距离市中心距离呈负相关，这表明城市化程度对鸟类功能多样性有显著影响。柳州市繁殖鸟类功能性状呈聚集趋势，随机过程可能是群落组配的主要驱动力，标准化效应值（SES.MNTD.FD）与林地面积呈正相关性。强调了城市公园特征参数对鸟类多样性影响的多维性，研究结果为柳州市及其他类似中小型城市提供了鸟类多样性保护和城市公园规划的重要数据支持和实践指导。建议通过增加城市公园和林地面积，以及减缓城市化进程，有效保护和提升城市鸟类的物种多样性和功能多样性。 |

| Abstract: |
| Urbanization is recognized as one of the primary drivers of biodiversity fluctuations. To examine the influence of urban park characteristics （such as park area， woodland area and the distance from the city center） on the species diversity and functional diversity of urban birds， we conducted bird detection by the line transect method in twelve urban parks in Liuzhou， Guangxi from April to August 2021. We employed multiple regression and generalized linear models to assess the influence of park characteristics on avian species diversity and functional diversity. Our findings indicated a positive correlation between the size of urban parks and bird species richness， suggesting that larger parks harbor greater species diversity. Additionally， the RaoQ index of bird functional diversity was positively correlated with the distance from the city center， while the functional evenness index showed negative correlations with both woodland area and distance from the city center， highlighting the significant impact of urbanization on functional diversity. The functional traits of breeding birds in Liuzhou exhibited an aggregation trend， and stochastic processes may be the primary driving force of community composition. Notably， the standardized effect value （SES.MNTD.FD） was positively correlated with woodland area. The study emphasizes the multidimensional impact of urban park characteristics on bird diversity. The results provide significant data support and practical guidance for bird diversity conservation and urban park planning in Liuzhou and other similar small and medium-sized cities. From the perspective of species conservation， it is recommended that increasing the size of urban parks and woodland areas， coupled with a slowdown in the pace of urbanization， can effectively protect and enhance the species diversity and functional diversity of urban birds. |
