滨海湿地生态修复与环境优化研究进展、战略机遇与挑战

Abstract

Abstract:

Coastal wetlands are mainly waters with a depth of less than 6 m during low tide and their coastal wetted areas. It includes permanent water bodies, intertidal zone and coastal low-lying areas with a water depth of no more than 6m. Wetlands have values such as regulating flows, preventing seawater intrusion, supplementing the sedimentation of nutrients from groundwater, regulating climate, maintaining biodiversity, protecting coasts, carbon sequestration and storage, developing ecological tourism, and undertaking education and scientific research. The global coastal wetland area is approximately 142000000 hm², and China has approximately 5940000 hm² at present. With the rapid growth of population, socio-economic development, and industrialization and urbanization processes in coastal areas, the global coastal wetland ecosystems are being severely degraded, and comprehensive protection measures are urgently needed. This article summarizes the technological progress of coastal ecological restoration and environmental optimization both domestically and internationally, and analyzes relevant achievements and cases. It summarizes the characteristics and advantages of China's coastal wetland ecological restoration technology, especially the new achievements made ever since the implementation of the Beautiful China Ecological Civilization Project, which has important reference significance and demonstration role for coastal ecological restoration and environmental optimization, and proposes suggestions and promotion measures for ecological restoration and environmental optimization of the China's coastal wetlands, to support the construction of the national “Carbon Peaking and Carbon Neutrality” strategy and sustainable development of marine economy.

Key words: coastal wetlands, ecological restoration, environmental optimization, opportunities and challenges
