Research on Ecological Restoration Strategy in the Semi-enclosed Sea Area: A case study in the Bohai Sea

Abstract

As the only semi-enclosed sea area in China, the Bohai Sea is the strategic support and key support for the vigorous development of Beijing-Tianjin-Hebei Urban Agglomeration. The stability of its ecological environment is closely related to the well-being of coastal human beings, and its ecological environment restoration has become a research hotspot in recent years. This study focused on the analysis of the impact of global climate change and human activities on the ecological environment of the Bohai Sea, and comprehensively compared and analyzed the successful cases of ecological restoration in similar waters at home and abroad. Based on the characteristics and present situation of the Bohai Sea, some ecological restoration principles such as dynamic thinking and holistic preservation, habitat connectivity restoration principles, and different spatio-temporal scale restoration principle were proposed. It also pointed out that the ecological restoration of the Bohai Sea required rational planning of fishery economic activities, and overall consideration of the relationship between the Bohai Sea ecology and flushing water. It was recommended to use a forward-looking thinking model and concept, reasonably predict, plan, locate, configure, implement and maintain the stability of the Bohai Sea ecosystem, and focus on exploring the best adaptive management strategies to deal with global climate change.
