摘　　要：稳定性同位素技术是生态学的重要研究手段,该文将稳定性同位素技术应用于生态学开放实验教学,设计了基于稳定性同位素的有机质分解测定实验。该实验探究性强,学生参与度高,拓宽了学生对生态学研究方法的认知,有助于学生了解稳定性同位素技术在生态学研究领域中的应用,同时大大提高了学生设计、参与相关生态学实验的能力。Stable isotope technology is an important research means of ecology. In this paper, the stable isotope technology is applied to the open experiment teaching of ecology, and the experiment of organic matter decomposition based on stable isotope is designed. This experiment has strong inquiry with high students’ participation, which broadens students’ understanding of ecological research methods, helps them to understand the application of stable isotope technology in the field of ecological research, and greatly improves their ability to design and participate in relevant ecological experiments.
