摘要: : The biogenic volatile organic compounds (VOC) emitted by the vegetation of a terrestrial ecosystem play key role in both regional air quality and tropospheric chemistry. To describe general emission properties VOC different plant functional groups (PFG) typical temperate grassland Inner Mongolia, China, we randomly selected 175 species measured quantities isoprene monoterpene situ. Results showed that most plants had low potential at level, especially for some dominant plants, such as Leymus chinensis Tzvel., Stipa grandis Smirn., Agropyron cristatum Gaertn. At PFG lowest was found perennial rhizome grasses, major ecosystem. effects overgrazing subsequent succession on life form (PLFG) were also discussed. ( Managing editor: Ya-Qin HAN)
