| Abstract: | Stable isotopes are extensively applied into areas of ecology,such as pollutant compounds of carbon and nitrogen attenuation,metabolic process and elements trace in ecosystem,etc.Through the review on research of denitrification process in riparian area,including limiting factors,rate and mechanism,the main advantage of approach is explained as the capability to indicate and discern the cumulative effect of spatial and temporal change on substance transfer.Mechanisms on how to realize a healthy state of rip... |
