苏州市吴中区是洞庭碧螺春茶叶的原产地，茶产业的发展不仅是当地农业的重要发展产业之一，还为当地带来了可观的经济效益，然而当地茶园的碳排放量和碳汇能力尚未明晰。以吴中区17个生态茶园的生产物资投入产出数据为基础，基于净碳足迹的研究方法，估算了茶叶生产的碳排放强度和碳汇能力，并据此进行了低碳生态茶园的发展分析。结果表明:在苏州市吴中区17个茶园的生产过程中，上游农资投入所产生的总平均碳排放量为27410。33kg CO2eq，因肥料施用所产生的碳排放量占总碳排放量的比例最大为90。94％，劳动力、农药和柴油等农用生产资料所产生的碳排放量分别为2131。48、204。92、147。71 kg;茶园生态系统所固定的总碳量为38632。77 kg CO2eq，其中茶园的平均净碳足迹为-11222。44 kg CO2eq，单位面积碳足迹为210。15 kg CO2 eq/亩，可有效固定环境中的温室气体，起到固碳增汇效果。通过研究分析比较可知，当地茶园在固碳方面仍具有较大的潜力，因此应通过优化茶园肥料施用、加强生态茶园理念推广和专业人员的作业能力以及建立生态茶园碳汇方法评价体系等来实现洞庭碧螺春生态茶园的未来低碳产业可持续性发展。
Carbon Footprint Estimation of Dongting Biluochun Tea Production in Suzhou,China
Suzhou City is the origin of Dongting Biluochun tea.The development of the tea industry is not only one of the important development industries of local agriculture,but also brings considerable economic benefits to the local community.Nevertheless,the carbon emission and sink capacity of local tea plantations are not yet clear.Based on the input and output data of 17 eco-tea gardens in Wuzhong District,this study estimates the carbon e-mission intensity and sink capacity of tea production based on the net carbon footprint research approach,and an-alyzes the development of low-carbon eco-tea gardens accordingly.The results showed that during the production process of 17 tea gardens in Wuzhong District,Suzhou City,the total average carbon emissions from upstream ag-ricultural inputs were 27,410.33 kg CO2eq,and the carbon emissions due to fertilizer application accounted for the largest proportion of the total carbon emissions of 90.94％.The carbon emissions from agricultural means of pro-duction such as labor,pesticides,and diesel fuel were 2,131.48,204.92,147.71 kg,respectively;the total carbon fixed by the ecosystem of the tea plantation was 38632.774 kg CO2 eq,of which the average net carbon footprint of the tea plantation was-11222.444 kg CO2eq,and the carbon footprint of per667m2 was 210.154 kg CO2eq,which can effectively fix the greenhouse gases in the environment,and play the effect of carbon sequestration and sink enhancement.Through research and comparison,it can be seen that local tea gardens still have great potential in carbon sequestration.So,the future sustainability of low-carbon industry in Suzhou's eco-tea gardens should be a-chieved by optimizing the application of fertilizers in the tea gardens,strengthening the promotion of the concept of eco-tea gardens and the operational capacity of professionals,as well as establishing an evaluation system of eco-tea gardens'carbon sinks methodology.
