报告摘要： 

Carbon neutrality requires both deep emission reductions and active removal of CO? from the atmosphere. Carbon-negative ecosystem technologies enhance natural sinks, stabilize biomass carbon, and reduce greenhouse gas emissions from waste treatment and land management. This study examines biochar production and soil application, black soldier fly (BSF) bioconversion, integrated COMBI systems, field trials with Pennisetum, and biomass conversion into DMF, hydrogen, and biodiesel. Available evidence indicates that biochar can stabilize biomass carbon and improve soil carbon stocks; BSF can divert organic waste carbon into larval biomass and lower greenhouse gas emissions compared with composting or landfilling; and integrated systems may achieve net-negative emissions when coupled with renewable energy and product substitution. However, the evidence remains preliminary. Methodological details, uncertainty analysis, long-term field data, and published references are limited. Key uncertainties include carbon accounting boundaries, biochar carbon durability, BSF scalability and life-cycle performance, and the external validity of field trials. Future work should standardize carbon accounting, conduct long-term multi-site trials, complete full life-cycle assessments, clarify biochar–BSF mechanisms, and develop transparent AI-assisted optimization platforms. These technologies are promising but require stronger evidence before large-scale deployment.
