In order to deal with the global warming, the invention provides a systematic method for ecologically reducing the emission of carbon, in particular relates to a systematic method for reducing the emission of carbon which includes the raw material resource, preparation process, storage and functional use of ecotype stabilized functional carbons (SFCs). .The method reduces the total volume of carbon cycle, and has the scope feasibility, economic feasibility, resource feasibility, ecological feasibility and technical feasibility of reducing 5-100 hundred million tons of carbon emission all over the world. The SFCs are obtained by carrying out seven thermochemical processes and dehydration and drying process on vegetable or animal organic substances with the carbon conversion rate being not less than 75%. The method converts the biological organic substances which is readily decomposed by biological oxidation into the SFCs with the carbon structure which has a stable sate period of more than 40 years, realizes primary ecological carbon emission reduction and non-carbon element emission reduction with the stable carbon storage bank of the SFCs, and realizes the advanced ecological carbon emission reduction and the non-carbon emission reduction by controlling and reducing the carbon emission at a plurality of carbon emission sources with the functional carbon utilization bank of the SFCs.
