The biological volatile organic compounds (BVOCs) had large emissions and high chemical activity,which was of great influence on the atmospheric environment quality,the climate change,the carbon cycle and so on. The source,composition,synthesis and release mechanism of BVOCs,the emission rate of different plants,the emission flux of different dimensions in China was introduced. At last,the development of BVOCs emission model in the future was presented which could provide reference to the reasonable selection and configuration of plant species in the view of the atmospheric pollution prevention and control.
