Analysis of the impact of highway engineering construction on birds in coastal wetlands
[Objective]The Mangzhou Wetland is located in the Hengqin Guangdong-Macao Deep Cooperation Zone of Zhuhai City,which is an important relay station on the migration route of"East Asia Australia"migratory birds.In order to study the impact of the construction and operation of the Honghe Bridge project on the birds in Mangzhou Wetland and provide reference for the bird protection work of other highway projects crossing coastal wet-lands.[Method]this article uses a field survey method with fixed sampling lines to compare the bird situation before the construction of the Honghe Bridge project in Zhuhai.It analyzes the impact of the construction and operation peri-ods of the project on the species and quantity,residential types,and key protected birds of birds in the Mangzhou Wetland.[Result]The research results indicate that from 2013 to 2022,a total of 123 bird species belonging to 15 or-ders,44 families,were recorded in the Mangzhou Wetland;From 2018 to 2020,due to the construction of the Honghe Bridge,the species,quantity,and dwelling types of birds in the Mangzhou Wetland significantly decreased.The con-struction period of the Honghe Bridge had a significant impact on the number of bird species in the Mangzhou Wet-land.After ecological restoration in 2021,the species,quantity,and dwelling types of birds in the park showed an up-ward trend;During the construction of the Honghe Bridge,the species of resident birds in the Mangzhou Wetland re-mained basically stable;Compared with the survey results before construction,the trace of rare protected birds found in the survey and monitoring during the construction and operation period of the project has been found,and the num-ber of rare protected birds has increased significantly during the operation period,but there are also some birds,which only appeared in 2013 or 2018,and there is no record in the future.[Conclusion]The impact of the Honghe Bridge construction project and operation on birds mainly comes from human interference,noise disturbance,and light source influence during the project construction and operation period;The main impact objects of engineering construction and operation are winter migratory birds;After the completion of the project,there has been a significant increase in the number of species,including protected birds;The impact of highway engineering on coastal wetland birds mainly occurs during the construction period,and protection measures should be strengthened during the con-struction period.
