中文摘要	2017年7月,采用动态箱采样法对内蒙古沙漠化草原的生物源挥发性有机物(BVOC)进行了研究,同时记录了温度、湿度和光合有效辐射等参数.结果表明:沙漠化草原羊草和冰草均排放了异戊二烯、alpha-蒎烯、beta-蒎烯、alpha-水芹烯、3-蒈烯、alpha-萜品烯、对伞花烃、柠檬烯、gamma-萜品烯、萜品油烯、罗勒烯和崁烯等12种挥发性有机化合物,羊草和冰草排放的BVOC平均排放通量分别为:(578.7692.39),(35.5120.23),(23.625.62),(380.48206.97),(15.704.72),(36.2110.53),(62.4610.36),(36.6322.83),(85.4448.33),(5.595.33),(17.623.32),(173.39201.97)mug/(m~2·h)和(587.36298.57),(7.240.28),(80.090.32),(204.49122.10),(4.640.83),(9.963.32),(18.865.73),(4.494.37),(63.0227.51),(7.265.09),(23.061.86),(32.3026.29)mug/(m~2·h);羊草和冰草BVOC 排放通量与温度和光合有效辐射变化规律呈现一致性,但各草种所受影响因子不尽相同,且其排放过程复杂,除冰草异戊二烯排放通量在15:00和17:00达到峰值外,其余BVOC排放通量与羊草BVOC排放通量均在11:00和15:00达到峰值.
英文摘要	In July 2017,a dynamic chamber system,simultaneously recording air temperature,relative humidity and photosynthetically active radiation,was employed to study the emission of biogenic volatile organic compounds (BVOC) from desert grassland of Inner Mongolia.The results showed that Leymus chinensis and Agropyron cristatum growing in desert grassland emitted isoprene,alpha-pinene,beta-pinene,alpha-phellandrene,3-carene,alpha-terpinene,p-cymene,limonene,gamma-terpinene,terpinolene,ocimene and camphene,with the average emission fluxes of (578.7692.39),(35.5120.23),(23.625.62),(380.48206.97),(15.704.72),(36.2110.53),(62.4610.36),(36.6322.83),(85.4448.33),(5.595.33),(17.623.32),(173.39201.97)mug/(m~2·h) from Leymus chinensis and (587.36298.57),(7.240.28),(80.090.32),(204.49122.10),(4.640.83),(9.963.32),(18.865.73),(4.494.37),(63.0227.51),(7.265.09),(23.061.86),(32.3026.29)mug/(m~2·h) from Agropyron cristatum,respectively.The changes of BVOC emission fluxes were consistent with that of air temperature and photosynthetic effective radiation,but the influencing factors were different from plant to plant,and the emission processes were complex.The emission fluxes of BOVCs peaked at 11:00 or 15:00,except isoprene emission from Agropyron cristatum were higher at 15:00 and 17:00.
