| Abstract: | The paper summarized the fundamental mechanism,application way,application method and advance of traces istopes C and N in agriculture and forestry.The application of isotope C mainly involved in soil C cycling processes,photosynthesis and the production of photosynthesis transportation and distribution,tree water use efficiency,land use conversion,residual,metabolism and decomposition of pesticides.The application of isotope C mainly involved in the mechanism N releasing from a N2O storage in agriculture and forestry,analysis of N fixation abilty,N mineralization,use efficiency of nitrogenous fertilizer.It will provide further reference for Tracer Isotope C and N in Agriculture and foresty. |
