| 摘 要： | 以兰州市常见的绿化树种槐树(Sophora japonica L．)的成熟叶片为材料，从细胞膜渗漏率、光合色素含量、叶提取液pH值、脯氨酸含量、SOD酶活性等方面探究了兰州不同地区大气污染对植物生理特性的影响．不同污染地区国槐叶片的叶绿素含量、可溶性糖的含量、叶提取液pH值随污染程度的加剧而减少，而细胞膜渗漏率、脯氨酸含量SOD酶活性则上升．数据综合分析表明：大气污染对植物生理特性的影响呈现连锁性状态．5个研究地点的污染程度由大到小的顺序为：白银(重工业污染区)＞西固区(重工业区)＞城关区(交通枢纽区)＞安宁区(居民区)＞红古区(轻度污染区)．

| Abstract: | Using mature leaves of one of familiar virescence trees species-Sophora japonica L.as experimental material,the effects of air pollution on plant physiology at different sites in Lanzhou City are studied from multi-facet,such as:cell membrane leakage rates,the contens of tissue water,SOD-amylase activtities,prolinc content and so on.The content of chlorophyll and the soluble sugarand and the pH value in leaves at five experimental sites decreased with the aggravation of pollution,cell membrane leakage rates and the contens of proline and the SOD-amylase activtities increased.The sequence of integrative pollutant index in different experimental sites from heavy to light is Baiying City>Xigu District>Chengguan District>Anning District>Honggu District. |
