Research on Optimization of Green Development Management of Mangroves based on Sustainable Development

Take Guangdong Province as an Example

Abstract

As a key ecosystem in the land-sea transition zone, mangroves have core functions such as carbon sequestration, biodiversity maintenance and coastal erosion resistance, but their sustainable development faces multiple challenges. Taking Guangdong Province as an example, this paper analyzes the global mangrove area reduction (about 147,000 square kilometers in 2020) and the current status of mangrove management in China, revealing the core problems it faces, such as spatial conflicts, policy lags, weak technology and insufficient social participation. The study proposes a five-in-one countermeasure system of "spatial planning-technological empowerment-capital innovation-industrial integration-institutional coordination", including hierarchical protection, intelligent restoration, carbon sink trading, industrial complexes and provincial legislation, aiming to resolve the contradiction between ecological protection and economic development and promote the transformation of mangroves from single protection to "protection-utilization" coordination. The study provides a systematic solution for ecological governance in coastal areas and helps the construction of blue carbon economy and ecological civilization.
