Abstract: About one-third of the global population lives in coastal areas, where they are not only typical areas of rapid globalurbanization but also important regions for the integrated and coordinated development of land-sea linkage and complex ecological functions. Focusing on the coast zone of Lin-gang Special Area, a rapidly urbanizing land-sea linkage area in Shanghai and based on 0.25 m-resolution aerial remote sensing images, the three-dimensional green volume and bird habitat quality were extracted from four rapid urbanization periods of 1987, 2010, 2015 and 2020 in order to explore the spatio-temporal dynamics of three-dimensional green volume and its impact on bird habitat qualities. Results indicate that firstly the green area and three-dimensional green volume in this area had increased from 1987 to 2020, with a 4.44-fold increase in green area and a 5.98-fold increase in three-dimensional green volume over the 33 years. The trend of the average habitat quality in Lin-gang Special Area exhibiting a V-shaped pattern that can be divided into a decline period from 1987 to 2015 and a recovery period from 2015 to 2020. Affected by reclamation disturbances, the area of high-quality habitats has gradually reduced during the urbanization of land-sea succession in the past 33 years. Secondly, correlation analysis using a 300 m×300 m grid reveals that there was a significant negative correlation between the three-dimensional green volume and bird habitat quality in this area before 2015. However, the relationship turned significantly positive afterwards, displaying a clear V-shaped reversal trend. The continuous increase in the three-dimensional green volume along the coastal zone has played a significant role in improving bird habitat quality. Therefore, the three-dimensional green volume can also be an important consideration when constructing bird ecological corridors.
