江苏农田土壤增强玄武岩风化的固碳潜力评估
Evaluation of Carbon Sequestration Potential via Enhanced Basalt Weathering in Jiangsu’s Farmland Soils
【摘要】 系统阐述农田土壤人工增强玄武岩风化的原理及过程,以江苏省自然条件和土地利用图为依据,科学评估其省域固碳潜力及经济成本。结果表明:江苏省玄武岩资源较为丰富,环境交通条件适宜,具有较强的固碳需求。以盱眙为中心,全省均在合理固碳范围内。若进入风化稳定期,年均可以固定CO2约3×107t,施用1 t玄武岩细微颗粒的费用在590元左右。但是这种固碳方式还存在技术不稳定、成本较高、公众接受程度较低等问题。为此,提出加强技术研究、降低应用成本、给予财政支持等措施建议。
【Abstract】 This paper systematically elaborates on the principles and processes of enhanced weathering of basalt in farmland soils.Based on the natural conditions and land use maps of Jiangsu Province, scientifically evaluates its provincial carbon sequestration potential and economic costs.The results reveal that: Jiangsu Province has relatively abundant basalt resources, suitable environmental and transportation conditions, and a strong demand for carbon sequestration.Centered around Xuyi, the entire province falls within a reasonable range for carbon sequestration.If a stable weathering period is achieved, the annual CO2 sequestration could reach approximately 3×107 tons, with the cost of applying 1 ton of finely ground basalt particles being around 590 yuan.However, this method still faces challenges such as technical instability, high costs, and low public acceptance.Therefore, the paper puts forward some suggestions; strengthening technical research, reducing application costs, providing fiscal support, and so on.
