摘　　要：基于市域尺度揭示了2006—2020年江苏省沿江地区耕地面源污染的时空演变特征,并借助Tapio脱钩模型进一步探究了耕地面源污染与农业经济增长的脱钩关系,以期为江苏省沿江地区耕地面源污染防治工作和长江流域农业绿色发展提供参考依据。结果表明,江苏省沿江地区耕地面源污染状况明显好转,且农药面源污染相较于化肥面源污染空间差异更明显;种植业单位面积产值总体呈上升趋势,且具有明显的空间差异性;农业生产与耕地面源污染的脱钩关系呈现出阶段性特征,且强脱钩聚集区出现位移。今后要持续推进化肥农药减量增效工作,加强耕地质量监测评价并建立土壤养护机制,整区域推进高标准农田建设,以实现农业生产与耕地面源污染的强脱钩。To provide a reference basis for the prevention and control of non-point source pollution of cultivated land in the area along the Yangtze River in Jiangsu Province and the green development of agriculture in the Yangtze River basin,based on the city scale,the spatio-temporal evolution characteristics of non-point source pollution of cultivated land in the area along the Yangtze River in Jiangsu Province from 2006 to 2020 were revealed,and the Tapio decoupling model was used to further explore the decoupling relationship between non-point source pollution of cultivated land and agricultural economic growth.The results showed that the non-point source pollution of cultivated land in the area along the Yangtze River in Jiangsu Province had significantly improved,and the spatial differences in pesticide non-point source pollution were more significant compared to fertilizer non-point source pollution.The overall output value per unit area of the planting industry was on the rise,with significant spatial differences.The decoupling relationship between agricultural production and non-point source pollution of cultivated land showed a phased feature,and the strong decoupling aggregation area showed displacement.In the future,the reduction and efficiency increase of chemical fertilizers and pesticides should be promoted,the monitoring and evaluation of cultivated land quality should be strengthened,soil conservation mechanisms should be established,and the construction of high standard farmland throughout the region should be promoted,to achieve strong decoupling between agricultural production and non-point source pollution of cultivated land.
