摘要
当前,我国农业面源氮污染对水体氮负荷的贡献率为60%~80%,面临点源面源治理失衡、政策碎片化及农户参与不足等困境,且现有生态补偿机制忽视氮污染的迁移性与乡村社会资本。该研究聚焦我国农业面源氮污染治理难题,通过构建“污染溯源—标准测算—制度设计—政策协同”全链条解决方案,创新设计生态补偿机制,并在长江中下游水稻种植区进行实证,从而验证了“经济激励—技术赋能—社区治理”三螺旋驱动模型的有效性,并提出精准补偿四象限政策启示,为农业面源氮污染治理提供参考。
Currently,agricultural non-point source(ANPS)nitrogen pollution contributes 60%to 80%to the nitrogen load in water bodies in China,facing challenges such as imbalanced point and non-point source governance,fragmented policies,and insufficient farmer participation.Further⁃more,existing compensation mechanisms often overlook the migratory nature of nitrogen pollution and rural social capital.Focusing on the tough issue of governing ANPS nitrogen pollution in China,this study constructs a full-chain solution encompassing"pollution source tracing—standard mea⁃surement—system design—policy coordination"to design an innovative ecological compensation mechanism.This mechanism was empirically tested in the rice-growing areas of the middle and lower reaches of the Yangtze River.The results verify the effectiveness of the"Three-Helix"driving model(integrating economic incentives,technological empowerment,and community governance)and derive policy implications for precise compensation based on a four-quadrant framework,provid⁃ing a reference for ANPS nitrogen pollution governance.
