中国蘭州市の農業生産システムを対象に、2000～2023年の炭素排出量と作物の炭素固定量を排出係数法で分析。プラスチックフィルムと肥料が主要排出源であり、羊の年間平均排出量は畜産全体の約半数を占める。作物の炭素固定量は年平均1.1%増加したが、排出量の増加率を下回り、農業持続可能性指標は54%となった。モンテカルロ法を用いた将来予測では、主要家畜の規模抑制が排出量抑制に有効と示唆。
English
This study analyzes carbon emissions and crop carbon sequestration in Lanzhou's agricultural system (2000–2023) using the emission factor method. Plastic film and fertilizers are major emission sources; sheep contribute about half of livestock emissions. Crop sequestration grows at 1.1% annually, slower than emissions, yielding a sustainability index of 54%. Monte Carlo simulations suggest limiting livestock scale to curb future emissions.

📄 Abstract（原文）
Strengthening the carbon sequestration function of agriculture and reducing carbon emissions during production are critical for enhancing the carbon neutrality capacity of agricultural systems. This study focuses on Lanzhou City in the arid northwest region of China, and uses the emission factor method to analyze carbon emissions and crop carbon sequestration within the local agricultural production system (2000–2023). The results indicate that plastic film and fertilizers, as agricultural production inputs, contribute substantially to the total carbon emissions of the planting industry, while the annual average carbon emissions from sheep account for approximately half of the total annual carbon emissions from animal husbandry. The annual average carbon sequestration of crops is 366,057 tons, with an average annual growth rate of 1.1%. The ratio of crop carbon sequestration to the total carbon emissions from planting and animal husbandry is approximately 2.1:1. Although the carbon sequestration of crops has increased over time, its average annual growth rate remains lower than that of carbon emissions from planting and animal husbandry, resulting in an Agricultural Sustainable Development Index of 54%. Therefore, further efforts are needed to control carbon emissions and increase the carbon sequestration capacity of crops to improve the sustainability of agriculture development in the region. Finally, the Monte Carlo algorithm is used to simulate and predict future carbon emissions from animal husbandry within the agricultural production system, thereby obtaining the relative trends in total carbon emissions from pigs, cows, and sheep over a given period. Limiting the scale and growth rate of major livestock populations can help limit the increase in carbon emissions from animal husbandry.
