摘要
根据嘉兴市实际农林产品产量和土壤含碳量测算了主要农作物和森林每年吸收二氧化碳672.8万t,释放氧气489.3万t,每年固碳制氧生态价值达102.36亿元,远超过当年度农林业产品价值60.19亿元。另外,嘉兴市土壤贮存碳汇也高达860.7万t。根据当地农业特点,提出了改造传统农业,发展低碳农业技术的策略。
On the basis of the actual output of agricultural and forestry products and soil carbon content in recent years,the absorption of CO2 by major crops and forests was 6.728 million tons and release of O2 was 4.893 million tons in Jiaxing,and the ecological value of annual carbon sequestration was 10.236 billion yuan,which was far more than the yearly agricultural and forestry products worth of 6.019 billion yuan.In addition,the soil carbon storage capacity was also high up to 8.607 million tons.According to local agricultural characteristics,the technical countermeasures in transformation of traditional agriculture and development of low-carbon agriculture were proposed.
