中文摘要：
采用二次热解析仪与GC—FID联用技术对沈阳地区8种典型绿化树种生物源挥发性有机物（BVOCs）的排放速率进行了观测和研究。结果表明：银中杨和垂柳的BVOCs排放量显著高于其它6种树木，排放速率分别为97．63和18．24μg·（g·h）^-1。阔叶树中银中杨、垂柳、丁香、水腊主要排放异戊二烯，排放速率分别为97．33、17．71、3．78、0．13μg·（g·h）^-1，榆树、皂角、银杏主要排放柠檬烯，排放速率分别为0．60、1．64、2．00μg·（g·h）^-1；而针叶树油松以排放α-蒎烯为主，排放速率为2．25μg·（g·h）^-1。
英文摘要：
An experiment was conducted to determine the emission rates of Biogenic Volatile Organic Compounds （BVOCs） from eight major afforestation tree species in Shenyang area by twice thermal desorption instruments using GC-FID techniques. Results showed that the emission rates of BVOCs from Populus alba x P. berolinensis and Scdix babylonica were 97.63 and 18.24 μg·g^-1·h^-1 respectively, which were significantly higher than those of the other six tree species. The deciduous trees, such as P. alba × P. berolinensis, S. babylonica, Syringa oblata and Ligustrum obtusifolium, mainly emitted isoprene, and their emission rates were 97.33, 17.71,3.78, 0. 13 μg·g^-1·h^-1, respectively; while Ulmws pumila, Gleditsiajaponica and Ginkgo bilotm predominantly emitted linaonene, and their emission rates were 0. 60, 1.64, 2.00 μg·g^-1·h^-1, respectively. The coniferous trees like Pinus tabulaeformis mainly released cz-pinene, and its emission rate was 2.25 μg·g^-1·h^-1.
