磷同位素示踪技术在生态与资源环境科学研究中的应用

he use of tracers are widely to plant-soi-manue duction-environment systems which study activity of phosphorus,forms changes,utilization and changes.It induces the development of ecology and sorce environment.This review shows the approache of tracer in plant-soi-manue duction-environment systems which include direct labeling technique, indirect labeling technique or exposed directly. The use of stable isotopes of oxygen in phosphate made it possible to quantify the phosphrus cycling under field canditions and aer system.But it is limited in plant and soil systems. NMR techniques was widely used to sduty the changes of phosphorus forms.It suplyes a new tools to qanlity and quantity of diffrenct forms of phophrus.
