| Abstract: | It has been an increasing trend of the studies in ecological research using stable isotope techniques since recent two decades.In this paper,the progress of the application of stable isotope techniques in the study on soil salinization at home and abroad is briefly reviewed.As the new but useful techniques,stable isotope techniques have been widely applied in the studies on the dynamic change of soil water evaporation,soil salinization and soil improvement as well as the salt-tolerant plant breeding.However... |
