Habitat loss, fragmentation and land-use change caused by the continued expansion of human settlements pose a threat to global biodiversity. Residential green spaces (RGs) are widespread throughout urban areas, providing benefits to human health and well-being and opportunities to conserve biodiversity. While RGs are fragmented by buildings and frequent human activities, little is known about their ability to support and conserve biodiversity relative to that of urban parks. To assess the ability of these green spaces to support biodiversity, we compared the bird species diversity, community composition, and influencing factors in RGs with those in urban parks of different scales. Our results revealed that, similar to medium-sized urban parks, RGs are associated with high bird species richness and abundance. Distance from waterbodies was the only common factor affecting bird species richness in RGs and urban parks. Moreover, RGs were favoured by native birds and urban dwellers, and the bird communities in RGs differed from those in urban parks. The results demonstrated that RGs can provide opportunities for bird conservation and serve as the most convenient place for humans to interact with animals in nature. We recommend that urban planners and managers consider blue–green spaces and habitat construction to improve bird diversity within residential areas.

鸟类住宅绿地的价值：与不同规模城市公园的比较研究


人类住区的持续扩张导致栖息地丧失、破碎化和土地利用变化，对全球生物多样性构成威胁。住宅绿地 （RG） 遍布城市地区，为人类健康和福祉带来好处，并有机会保护生物多样性。虽然 RG 因建筑物和频繁的人类活动而分散开来，但相对于城市公园，人们对它们支持和保护生物多样性的能力知之甚少。为了评估这些绿色空间支持生物多样性的能力，我们将 RG 中的鸟类物种多样性、群落组成和影响因素与不同规模的城市公园中的鸟类物种多样性、群落组成和影响因素进行了比较。我们的结果表明，与中型城市公园类似，RG 与高鸟类物种丰富度和丰度相关。与水体的距离是影响 RG 和城市公园鸟类物种丰富度的唯一共同因素。此外，RG 受到本地鸟类和城市居民的青睐，RG 中的鸟类群落与城市公园中的鸟类群落不同。结果表明，RG 可以为鸟类保护提供机会，并成为人类与自然界动物互动的最便利场所。我们建议城市规划者和管理者考虑蓝绿空间和栖息地建设，以改善住宅区内的鸟类多样性。
