This invention relates to the field of wetland ecological environment monitoring and greenhouse gas emission reduction technology, specifically to a method for assessing the impact of microplastics on methane emissions from wetland soils based on soil carbon composition. This invention assesses the degree of change in methane emissions from wetland soils after the addition of microplastics by measuring changes in the content of organic carbon components in the soil. Results show that, without relying on the detection of functional genes such as methanogens and methanogens, changes in the content of only two key carbon components—dissolved organic carbon and mineral-bound organic carbon—can accurately and quickly assess the direction and intensity of the impact of microplastics on methane emissions from wetland soils. This demonstrates the feasibility, scientific validity, and practicality of the method, providing a simple, efficient, and easily scalable new approach for assessing methane emissions from greenhouse gases under microplastic pollution stress in ecosystems.

The present application relates to the technical field of wetland ecological restoration, and particularly relates to a nitrogen reduction, carbon fixation and emission reduction method for coastal wetlands based on iron cycle. The present application mixes biochar raw materials with water, and then performs hydrothermal reaction to obtain biochar precursors; the biochar precursors are immersed in a tannic acid modification solution to perform modification to obtain modified biochar precursors; and the modified biochar precursors are pyrolyzed under the condition of ferrocene vapor and inert atmosphere to obtain modified biochar.
