DYNAMIC MONITORING AND MANAGEMENT STRATEGY OF FOREST CARBON SINK

ABSTRACT

As an important means to cope with global climate change, the study of forest carbon sink dynamic monitoring and management strategies is of great significance. The purpose of this study is to realize real-time dynamic monitoring of forest carbon sink through comprehensive application of remote sensing technology, geographic information system and machine learning algorithm, and propose effective management strategies. Background Based on China's rich forest resources and the increasingly severe challenge of climate change, this study selected several typical forest areas for data collection and analysis. Firstly, high-resolution satellite images were used to obtain forest cover data, and then corrected with ground measured data. Secondly, GIS technology is used to construct spatial database to realize data integration and management. Finally, the random forest algorithm is used to predict and evaluate the carbon sink. The results show that the proposed method can accurately reflect the temporal and spatial characteristics of forest carbon sink, and the prediction accuracy is more than 90%. In addition, the study also found that different forest types and management measures have significant effects on carbon sink. The conclusion shows that this study not only improves the accuracy and efficiency of forest carbon sink monitoring, but also provides theoretical basis and technical support for formulating scientific and reasonable forest management policies.
