Dissipation Theory-Based Ecological Protection and Restoration Scheme Construction for Reclamation Projects and Adjacent Marine Ecosystems

Abstract

According to the 2017 results of the Special Inspector of Sea Reclamation, a substantial number of idle reclamation zones existed in 11 provinces (cities) along the coast of China. To improve the protection level of coastal wetlands and strictly control reclamation activities, it is necessary to carry out ecological restoration of reclamation projects and adjacent marine ecosystems. The characteristics of Guanghai Bay and its reclamation project are typical in China’s coastal areas, making it an optimal representative site for this study. The dissipative structure and entropy theory was used to analyze ecological problems and environmental threats. The analytic hierarchy process was applied to determine the order of the negative entropy flow importance. The entropy increase and decrease mechanism was used to determine an ecological protection and restoration scheme for the reclamation, including the reclamation of wetland resource restoration, shoreline landscape restoration, environmental pollution control, and marine biological resource restoration. Finally, based on system logic, a typical ecological restoration system was constructed east of Guanghai Bay, with the mangrove wetland area as the model in the north and the artificial sandbeach recreation area as the focus in the south.

Protection pattern and driving mechanism of typical marine ecosystems: a case study of China-ASEAN countries

“…Coral reefs, seagrass beds, and mangroves are three important ecological types in marine ecosystems, and their presence and health are directly related to the stability and biodiversity of marine ecosystems (Moberg and Rönnbäck, 2003). The importance of these marine ecosystems is gradually being recognized, and various conservation measures are continuously being proposed (Huang et al, 2019). The establishment of marine protected areas plays a crucial role in the protection of typical marine ecosystems in the region (Yacob et al, 2009;Hu et al, 2020).…”

Multi-Phase Environmental Impact Assessment of Marine Ecological Restoration Project Based on DPSIR-Cloud Model

“…Many scholars have carried out various studies on ecological restoration assessment. However, most studies have focused on comparative analysis after the completion of targeted projects, putting forward measures and technologies for constructing ERP, and evaluating the technologies and schemes from the perspectives of marine health and other aspects [ 10 , 11 , 12 ]. However, the impact of these projects on the sensitive coastal environment is not mentioned, and human activities also have a destructive impact on the restored coastal environment.…”
