摘要

Large-scale airport construction removes large quantities of earth materials, resulting in serious environmental pollution and ecosystem damage. However, studies of environmental concerns caused by the materials used in airport construction are still preliminary, and those case studies on the impacts of large-scale offshore airport development are very limited. China's Dalian Offshore Airport is considered here to study the environmental value loss from 240 million m(3) of materials excavations and 21 km(2) of artificial island infillings. The findings show that the calculated annual environmental value loss for the development of the Dalian Offshore Airport is approximately US$7.75 million, including US$1.81 million and US$1.47 million of direct economic loss of timber resources and marine biology resources, respectively, and US$1.53 million and US$2.79 million value losses of forest and marine ecosystem services damaged caused by materials excavation and infilling, respectively. The conclusions of this study provide an important foundation to quantitatively analyse the environmental impact of the Dalian Offshore Airport's development and can be used as a reference for similar engineering and environment impact assessment programs.
