【摘要】 用喷淋法对110种供试树木的枝条分别进行不同pHAR处理和在开顶式熏气罩内进行不同浓度的SO2暴露试验，以及先喷AR后接触SO2的复合暴露试验．结果表明，不同树种对AR和SO2暴露显示了不同的抗耐性和敏感性．更多还原

【Abstract】 This peper described the response of 110 species of trees which were exposed to acid rain and SO2 aloneand in combination. The twigs of the trees were treated by spraying AR (pH 2. 0, 3. 0, 4. 5 and 5. 6, respectively) or exposing to SO2[ρ(SO2) 1. 0, 2. 0, 3. 0 4. 0 mg/m3, respectively ] in open top field chambers. In the test of complex exposure, The twigs were firstly treated by spraying AR and then by axposing toSO2. The results indicated that the resistance and sensitivity to AR and SO2 varied with different species oftrees,and their damages also varied in different ways.更多还原
