Abstract
With the development of cities and the continuous expansion of human activities, the impact of humans on nature has gradually become prominent. After the Industrial Revolution, the relationship between humans and nature has undergone a subtle change. Whether human beings actively interfere with nature or unconsciously influence the natural environment through behavioral facts, the progress of many human societies is accompanied by the consumption and damage of natural energy. At the same time, nature is also using facts to remind humans that the environmental degradation caused by excessive intervention will eventually affect humans themselves. This study collected 2003, 2012, 2016, and 2019 survey data of seawater quality and ecological environment near the Tianjin Dongjiang Port area. Through a single factor analysis method, we found that the marine environment changes in this area in recent years. The development of Tianjin’s urban area is closely related to the development of the port. At the same time, the sea reclamation project in Dongjiang may also be one of the reasons for this change. sea reclamation project in Dongjiang may also be one of the reasons for this change.
Highlights
Tianjin Port is located in Binhaixinqu, Tianjin, China
In order to fully assess the environmental changes in the sea area before and after the Dongjiang Port Reclamation, and evaluate and analyze the degree of marine environmental changes in the sea area where the project is located, the assessment data shall be screened according to the following principles that the survey time is before, during and after reclamation construction, and the survey try to in the same season
The changes in the marine ecology of the waters near the Bohai Bay and Tianjin are closely related to the quality of seawater
Summary
Tianjin Port is located in Binhaixinqu, Tianjin, China. It is located at the western of the Bohai Bay. In 1860, Tianjin Port opened to the outside world and became a commercial port. The problem of the deterioration of the marine environment in the Bohai Bay has always existed. The reasons may lie in the following aspects. The Bohai is semi-closed inland sea, the water exchange capacity is average, and pollutants are relatively difficult to spread. The second, Bohai coasts have a high degree of urbanization. With rapid development in recent decades, cities have expanded rapidly, and discharged a lot of waste
