氧同位素技术在土壤-植被-生态-环境研究中的应用进展与展望
Research progress and prospect of oxygen isotope technique in soil-vegetation-ecology-environment studies
摘要
Abstract
This paper is the result of environmental geological survey engineering. [Objective]Oxygen is one of the basic elements that make up living matter,and the oxygen cycle in nature is the basic guarantee for life activities.Oxygen isotope technology is a powerful tracer that can effectively indicate biogeochemical cycling processes and has been widely used in ecological and environmental research.[Methods]This paper reviewes the fractionation mechanism of oxygen isotopes and its application in soil-vegetation-ecological environment by reviewing a large number of literatures on oxygen isotopes.[Results]Depending on the large isotope mass ratio difference,oxygen isotopes can undergo the greatest degree of isotope fractionation under natural conditions.The application of oxygen isotopes mainly includes three aspects:(1)Tracing the source of environmental pollutants;(2)Paleoenvironment and paleoclimate restoration;(3)Tracing the geographical origin of food(animals).[Conclusions]In practice,oxygen isotopes are usually used together with other isotopes(hydrogen,carbon,nitrogen,etc.)to track multi-dimensional climate,vegetation development,and geographical location.In the future,oxygen stable isotopes can be combined with substitute models in the fields of global change,such as tree rings,foraminifera,loess,and salt lakes,and play a more important role in environmental ecology research.关键词
