Carbon Sink Grass and Its Carbon Sink Mechanism

The carbon emission reduction mechanism proposed by the Kyoto Protocol includes application of solar energy，wind power，hydropower and geothermal energy，carbon capture and storage（CCS），industrial emission reduction and carbon sink forest planting.However，such mechanisms do not actually restrain dramatic increase of atmospheric CO2.To resolve this crisis，a novel carbon sink mechanism-carbon sink grass planting was raised，and definition of carbon sink grass was confirmed in the present study.The carbon sink grass could rapidly accumulate biomass by repeated mowing，sequestration and conservation.Audited by China Quality Certification Center，the net carbon sink amount of carbon sink grass was 210 thm2 per annum.Nowadays，the global forest area and the total carbon storage are continuously decreasing，therefore the exploitation of novel carbon sink mechanism is quite urgent.Compared with the forest resources，the totally carbon sink increment in 50 years of grass is approximately 650-fold of that of the forest in same proportion.According to estimates，the total amount of CO2 in the atmosphere is about 3.11 trillion ton.Supposed 6 661 trillion ton plant carbon products could capture 9 725 trillion ton CO2 from the atmosphere，then the atmosphere CO2 concentration would decline from 0.04% to 0.0275%，which is equivalent to the CO2 concentration before industrial revolution，and to achieve this goal need plant only about 1 billion hectares of carbon sink grass.Moreover，the extremely strong survivability ensures the carbon sink grass could be planted in marginal land，polluted land，wetlands and water instead of farmlands.The novel mechanism initiated in the present research could control the global climate change and the greenhouse effect by regulating the CO2 concentration in the atmosphere.This project could not only resolve climate deterioration and environmental issues，but also obtain abundant biomass resources.
