稳定氮同位素示踪技术在农业面源污染研究中的应用

摘要

The theory of 15N trace was briefly summarized. And its applications on tracing nitrogen source, nitrogen cycling process and fate of nitrogen fertilizer were reviewed and discussed. The prospective of the research on agriculture non-point source pollution was proposed.%在对稳定氮同位素示踪技术的基本原理进行了简要的论述后,从示踪氮源、氮循环过程和化肥氮去向3个方面探讨稳定氮同位素示踪技术在农业面源污染中的应用,并结合该领域现状探讨其研究前景.
