摘　　要：通过在不同大气污染的环境下测定吉林市主要园林植物叶片的叶绿素a、b含量及其比率变化、电导率的变化及净光合速率(Pn)、蒸腾速率(T)、气孔导度(C)的变化,研究了不同环境条件下植物的适应性以及伤害程度,以期筛选出不同环境条件下适应生长的绿化树种。结果表明:适合在工业区种植的树种有红王子锦带、女贞、桃叶卫矛、梓树、小叶丁香;而适合在交通繁忙区种植的树种有梓树、白榆、桃叶卫矛、小叶丁香。In the environment of different air pollution of Jilin city,the chlorophyll a,b contents and their ratio changes,changes of the conductivity and net photosynthetic rate（Pn）,transpiration rate（Tr）,stomatal conductance（C） of the main garden plant leaves were determimed,the adaptability of plants under different environmental conditions as well as the degree of injury were studied to screen greening tree species under different environmental conditions.The results showed that Weigela florida,Ligustrum L.,Euonymus hamiltonianus,Catalpa ovata and Sytinga microphyla were suitable for industrial zone.Catalpa ovata,Ulmuspumila L.,Euonymus hamiltonianus and Sytinga microphyla were suitabe for heavy traffic area.
