伴随着大规模快速城市化的土地覆被变化造成了生物多样性的重大损失，迫切需要纳入生物多样性保护的城市规划。了解土地覆盖如何影响生物多样性指标物种繁殖地的分布和动态，有助于制定长期的、景观尺度的城市规划，以增强生物多样性。本文以日本神奈川市为研究对象，研究了影响生物多样性指标物种苍鹰孳生地分布和动态的土地覆盖因子。利用logistic回归模型分析了繁殖地有无数据与土地覆盖因子的相关性。为了评价繁殖地分布的动态，采用元种群动态模型分析了6年来繁殖地占用历史与土地覆被因子的关系。森林覆盖、开阔地和高度植被覆盖对苍鹰繁殖地的分布有正向影响。然而，高度植被覆盖的城市覆盖的相对重要性不如森林覆盖或开阔地。森林覆盖对当地灭绝概率有负向影响，而森林覆盖和开阔面积对当地殖民概率有正向影响。相比之下，高度植被覆盖对繁殖地分布的相对重要性较低，与繁殖地分布动态没有关系。森林覆盖和空地对苍鹰繁殖地分布和动态的重要性强调了这些土地覆盖类型对城市生活苍鹰繁殖地的重要性。因此，管理人员应注重维护森林和开放土地，以保护城市地区的苍鹰繁殖地，以促进它们的长期生存。高度植被的城市覆盖被认为对苍鹰繁殖地的长期生存能力不太重要。
Land cover change accompanying large-scale and rapid urbanization has caused major losses to biodiversity, with urban planning that incorporates biodiversity conservation being urgently needed. Understanding how land cover impacts the distribution and dynamics of breeding sites of biodiversity indicator species could facilitate the creation of long-term, landscape-scale urban planning to enhance biodiversity. Here, we identified land cover factors that influence the distribution and dynamics of the breeding sites of goshawks, a biodiversity indicator species, in the urban areas of Kanagawa, Japan. We analyzed how breeding site presence and absence data were correlated with land cover factors using a logistic regression model. To evaluate the dynamics in breeding site distribution, a meta-population dynamics model was used to analyze the relationship between breeding site occupancy history and land cover factors over 6 years. Forest cover, open land, and highly vegetated urban cover positively affected the distribution of goshawk breeding sites. However, the relative importance of highly vegetated urban cover was not as high as forest cover or open land. Forest cover negatively affected local extinction probability, while forest cover and open areas positively affected local colonization probability. In comparison, highly vegetated urban cover had low relative importance for the distribution of breeding sites, with no relationship being detected for breeding site distribution dynamics. The importance of forest cover and open land for both the distribution and dynamics of goshawk breeding sites emphasizes the importance of these land cover types for the breeding of urban-dwelling goshawks. Therefore, managers should focus on maintaining forests and open land to conserve goshawk breeding sites in urban areas to facilitate their long-term viability. Highly vegetated urban cover was considered to be less important for the long-term viability of goshawk breeding sites.
