基于营养-经济-生态耦合模型的从江稻鱼鸭复合系统碳足迹研究
Research on Carbon Footprint of Yangtze River Rice Fish Duck Composite System Based on Nutrition Economy Ecology Coupling Model
摘要
Abstract
In this paper,the carbon footprint per unit area(CFA),carbon footprint per unit value(CFV)and carbon footprint per unit nutri-ent density(CFNDU)of the rice-fish-duck composite system in the Dong Township of Congjiang County,a Globally Important Agricultural Cul-tural Heritage(GIAHC),were measured based on the research data of the farmers,and the life cycle assessment method was used to compare CFA,CFV and CFNDU of the composite system with that of the traditional rice-fish symbiosis and the conventional rice cropping.The results showed that the CFA,CFV and CFNDU of the rice-fish-duck composite system were 8 338.31 kg(CO2eq)/hm2,0.05 kg(CO2eq)/yuan and 8.32 kg(CO2eq)/NDU,respectively,and that of the rice-fish symbiosis model,CFA,CFV and CFNDU were 8 057.02 kg(CO2eq)/hm2,0.10 kg(CO2eq)/yuan,and 9.85 kg(CO2eq)/NDU,respectively;and in the conventional rice-fish cropping system,the CFA,CFV,and CFNDU were 9 908.22 kg(CO2eq)/hm2,0.30 kg(CO2eq)/yuan,14.49 kg(CO2eq)/NDU.The Rice-fish-duck complex system has the high-est nutrient density output(NDU),provides a variety of food sources,and helps to enrich the dietary structure of people's diet structure.Mo-reover,it has the smallest carbon footprint per unit of output value,which has a high potential for popularization and is an agricultural produc-tion model that balances economic benefits and environmental sustainability.关键词
