中文摘要:
      精准掌握长三角地区种植业碳排放现状并因地制宜制定减排策略,对于长三角绿色低碳一体化发展具有重要意义。本研究细化了研究尺度并完善了测算体系,在市级尺度下对2000—2020年长三角地区种植业碳排放进行测算,分析其时空特征,并围绕减排措施及减排潜力展开探讨。结果表明:2000—2020年该地区种植业碳排放量呈现持续下降-波动上升-持续下降的变化趋势,2014年碳排放量达到峰值7.17×107 t;2014年后农业GDP增长率上升,碳排放量下降,呈现出强脱钩的理想状态。长三角地区种植业碳排放量呈现北高南低的态势,高排放地区集中在皖中、苏中以及苏北地区,且排放量的空间重心从江苏省南京市逐年向北部的安徽省滁州市移动。通过实施水分管理、优化施肥方式、推广低碳水稻品种、整合耕地资源等措施,预计长三角地区种植业每年可减少碳排放量约1.84×107 t。本研究揭示了长三角地区种植业碳排放的动态特征、现状规律及空间差异性,丰富了该区域碳排放研究的理论框架,为制定有效的种植业碳减排策略和实现种植业低碳化转型提供依据。
英文摘要:
      Accurately understanding the current status of agricultural carbon emissions in the Yangtze River Delta region and formulating tailored emission reduction strategies are crucial for green and low-carbon integrated development of the area. This paper optimizes research scale and improves the calculation system to estimate carbon emissions from agriculture at the municipal level from 2000 to 2020 in the Yangtze River Delta, analyzes its spatiotemporal characteristics, and discusses emission reduction measures and potential. The results showed that from 2000 to 2020, carbon emissions from the agricultural sector in this region exhibited a“steady decline-fluctuating increase-steady decline”trend, with emissions peaking at 7.17×107 t in 2014. After 2014, the agricultural GDP growth rate increased and carbon emissions decreased, presenting an ideal state of strong decoupling. The carbon emissions from agriculture showed a“high in the north, low in the south”pattern, with high emission areas concentrated in central Anhui, central Jiangsu, and northern Jiangsu and the spatial center of emissions gradually moving from Nanjing to Chuzhou in northern Anhui. By implementing water management, optimizing fertilization methods, promoting low-carbon rice varieties, and integrating arable land resources, the Yangtze River Delta region could reduce its agricultural carbon emissions by approximately 1.84×107 t annually. This paper reveals the dynamic characteristics, current patterns, and spatial differences of agricultural carbon emissions in the Yangtze River Delta region, enriching the theoretical framework of regional carbon emission research and providing a basis for formulating effective agricultural carbon-emission reduction strategies and achieving low-carbon transformation in agriculture.
