| 在 “双碳” 目标战略指引下，我国农业生物质资源的高效开发及能源化利用已成为推动农业绿色低碳转型的重要路径，但在用能需求高的发达地区生物质能实际应用尚不充分，且对南方含水量高的生物质能源转化规律研究较少。基于此，本文立足于地处大湾区用能需求大的广东省，以省内农业发达的南雄市为主要研究对象，以期探索出符合我国南方地区农业生物质资源能源转化潜力及其规律。本研究依托南雄市国民经济和社会发展统计公报及实地调研数据，系统分析南雄市主要农作物种植情况及乡域分布特征，并开展生物质资源转化潜力评估。研究得知，2018到2022年南雄市粮食作物产量整体保持上升趋势，2023年南雄市主要农作物秸秆理论年产量达2.69×105 t，且以稻谷秸秆为主，占全市秸秆总量的60.22%；其中乌迳镇是南雄市秸秆资源最丰富的乡级区域，粮食作物稻谷占全市总量的8.61%，经济作物占全市总量的10.31%；以南雄市的水稻秸秆作为原料进行生物质制气，其产气量可达到3.89-4.76×107 m3·a-1，不考虑秸秆种类差异，南雄市可利用的秸秆资源总产气量高达4.11-5.09×107 m3·a-1，体现出巨大的产气潜力，且碳减排量能达到7.81-9.67×104 t CO2。在此基础上，提出生物质制气厂设置等相关建议，以实现更高效的秸秆资源化利用。该研究不仅可为地方生物质资源开发利用提供科学决策依据，也可为南方农作物秸秆规模化、高效化利用探索提供可复制推广的实践路径。 |

| Abstract: |
| Under the strategic guidance of China's "dual carbon" goals, the efficient development and energy-oriented utilization of agricultural biomass resources have become a crucial pathway for promoting green and low-carbon transformation in agriculture. However, the practical application of bioenergy remains insufficient in high energy-demand developed regions, and research on the conversion patterns of high-moisture biomass prevalent in southern China is relatively scarce. Addressing this gap, this study focuses on Guangdong Province—a major energy consumer within the Greater Bay Area—and specifically examines Nanxiong City, an agriculturally developed area within the province, aiming to explore the energy conversion potential and underlying patterns of agricultural biomass resources in southern China. Utilizing data from Nanxiong City's National Economic and Social Development Statistical Bulletins and field surveys, this research systematically analyzes the cultivation status and spatial distribution characteristics of major crops in Nanxiong and assesses the conversion potential of its biomass resources. The findings reveal that Nanxiong's grain crop output exhibited an overall upward trend from 2018 to 2022. In 2023, the theoretical annual yield of major crop straws reached 2.69 × 105 tonnes, dominated by rice straw which constituted 60.22% of the total. Wujing Town emerged as the township with the richest straw resources, contributing 8.61% of the city's total grain crop (rice) output and 10.31% of its economic crop output. When using rice straw from Nanziong City as feedstock for biomass gasification, the gas production can reach 3.89–4.76×107 m3·a-1. Disregarding variations in straw types, the total gas production potential from utilizable straw resources in Nanziong reaches 4.11–5.09×107 m3·a-1, demonstrating substantial production capacity with an associated carbon reduction potential of 7.81–9.67×104 t CO2. Accordingly, recommendations for establishing biomass gasification plants are proposed to enhance resource utilization efficiency. This study not only provides a scientific basis for local decision-making regarding biomass resource development but also offers a replicable model for exploring the large-scale, high-efficiency utilization of crop straw in southern China. |
