【摘要】 采用野外调查结合人工熏气法,在不同浓度梯度下对60种植物进行测试。从中筛选了樟树、杧果、夹竹桃等21种植物,它们对SO₂抗性较强,可作为绿化城市植物种,玫瑰、夜来香、四季海棠等9种植物,对SO₂具有显著敏感性,可作为污染“监测器”。更多还原

【Abstract】 We have done some tests on various concentration gradients among sixty kinds of plants through field survey and the method of artificial vaporization. We have chosen twenty-one plants such as the Cinnamomun eamphora, the Mangifera indica and the Nerium indicum for the plant species in and around the cities because their endurance against SO₂ is quite strong. We have also chosen nine plants such as the Rosarugosa, the Cestrum nocturnum and the Begonia semperflorens for the contamination "Monitor" because their sensibility against SO₂ is obvious.更多还原
