System for assessing population dynamics, primary productivity, and carbon flux of northward shifting mangrove forests

By coupling the ecological module and the hydrodynamic module in the assessment system, the problem of assessing the community development and carbon sequestration capacity of mangroves after northward migration was solved. This system enables accurate assessment of the community development and carbon sequestration capacity of mangroves after northward migration and prediction of future trends, supporting the protection of coastal wetlands and the management of blue carbon resources after the northward migration of mangroves.

AI Technical Summary

Technical Problem

Existing technologies are insufficient to accurately assess the development of mangrove communities and their carbon sequestration capacity after northward migration. They also fail to effectively consider the impact of complex climate, hydrology, and sediment changes on coastal wetland landforms, vegetation carbon sequestration, and systemic carbon cycling, leading to uncertainty in assessment results and deviations in simulation accuracy.

Method used

Develop a system for assessing the population dynamics, primary productivity, and carbon flux of northward-migrating mangroves. By coupling ecological and hydrodynamic modules, considering the impact of tidal processes on tidal flat landform changes and ecosystem carbon exchange, and refining the multi-process carbon cycle calculation module, the system can assess the community development and carbon sequestration capacity of mangroves after northward migration.

Benefits of technology

This study enabled accurate assessment and prediction of future trends of mangrove community development and carbon sequestration capacity after northward migration, providing a scientific basis for the protection and restoration of coastal wetlands and the management of blue carbon resources after mangrove migration, and improving the accuracy and reliability of the assessment.
