| 摘 要： | 采用污染现场定点采样,分析叶片受害后的生理生化指标数值变化。与对照区相比,以SO2、NO2为主要复合污染源的绿化区4种乔木的叶绿素含量下降区间是5.42%～55.11%,其中广玉兰在纸浆厂下降幅度最大达55.11%,发电厂最小是17.81%,重阳木在钢铁厂下降幅度最大达32.93%,纸浆厂最小为18.20%;香樟、杜英均是电厂污染下降幅度高于钢铁厂,纸浆厂下降幅度最小,广玉兰、重阳木则以钢铁厂下降幅度高于电厂。发电厂中各树种叶片可溶性糖含量的降低幅度依次是：广玉兰（20.35%）〉杜英（18.63%）〉重阳木（14.29%）〉香樟（12.63%）,钢铁厂是：重阳木（37.66%）〉香樟（37.20%）〉杜英（28.45%）〉广玉兰（14.11%）,纸浆厂是：重阳木（49.42%）〉杜英（42.72%）〉广玉兰（30.59%）〉香樟（23.08%）。发电厂各树种叶片质膜透性的增长率为38.48%～60.67%,钢铁厂为91.76%～110.96%,香樟增长率最高,其次是重阳木、杜英,广玉兰增长率最小;纸浆厂增长率为29.95%～106.49%,其中广玉兰增长率最高,杜英、香樟次之,重阳木最小。3类企业各树木叶片超氧化物歧化酶（SOD）含量较对照区增长范围22.99%～143.93%。叶片过氧化物酶活性（POD）的变化,各树种在电厂增加幅度是31.46%～67.23%,钢铁厂各树种叶片POD含量增加序列是：广玉兰（21.30%）〈杜英（41.77%）〈香樟（48.63%）〈重阳木（56.86%）,增加幅度是21.30%-56.86%,在纸浆厂则是广玉兰（6.14%）〈香樟（25.19%）〈杜英（25.60%）〈重阳木（31.74%）,增加幅度是6.14%-31.74%。综合分析得出,四种树木的抗污能力差异显著,并且相同树种对于不同企业污染的反应存在差异。对于抵抗厂区大气复合污染能力的高低序列是：广玉兰〉香樟〉重阳木〉杜英,结果为有针对性地开展污染企业绿化树种选择提供依据。

| Abstract: | Using collected leaf sampling in polluted area and analyzing the change of indicator of physiological and biochemical of leaves suffered from multiply pollution consisted with SO2 and NO2 in three enterprises.In compared with clear sited,the declined range of chlorophyll of 4 arbors was 5.42% - 55.71%,especially it was the highest reached 55.11% for Magnolia grandiflora in paper mill and the lowest was 17.81% in power factory,and the lowest decline was 18.20% in paper mill while the highest reached 32.93% in steel plant for Bischofia polycarpa.The declined range of Cinnamomum camphora and Elaeocarpus sylvestris in power factory were higher than that in steel plant,M.grandiflora and Ischemia polycarpa were on the other foot.Research results showed that the order of declined value of the content of dissolve sugar in leaves was follows： M.grandiflora（20.35%）〉E.sylvestris（18.63%）〉B.polycarpa（14.29%）〉C.camphora（12.63%） in power factory,it also showed that’s B.polycarpa（37.66%）〉C.camphora（37.20%）〉E.sylvestris（28.45%）〉M.grandiflora（14.11%）in steel plant while it was showed that B.polycarpa（49.42%）E.sylvestris（42.72%）M.grandiflora（30.59%）C.camphora（23.08%）in paper mill.The range of increase ratio of membrane permeability of cell of leaves was 38.48% - 60.67% in power factory,and it was 91.76% - 110.96% in steel plant,C.camphora has highest growth rate,followed by B.polycarpa and E.sylvestris,and M.grandiflora has the smallest growth rate;then increase ratio was 29.95% - 106.49% in paper mill,M.grandiflora has highest growth rate,followed by E.sylvestris and C.camphora and B.polycarpa has the smallest growth rate.The content of SOD in leaves in 3 kinds of enterprises was much more than 22.99% - 143.93% to clear areas（CK）,while range of increase ratio for the POD was 31.46% - 67.23% in power factory,21.30% - 56.86% in steel plant and 6.14% - 31.74% in paper mill.The order of content increment ratio to clear areas of POD was B.polycarpa（56.86%）C.camphora（48.63%）E.sylvestris（41.77%）M.grandiflora（21.30%）in steel plant while it was B.polycarpa（31.74%） E.sylvestris（25.60%） C.camphora（25.19%） M.grandiflora（6.14%）in paper mill.It was comprehensively analyzed that there existed obvious different ability of anti-pollution for four tree species above mention,and significant different response for the same tree species to various enterprises pollution,the order of anti-multiply pollution ability was as follows： M.grandiflora C.camphora B.polycarpa E.sylvestris,thus it can provide theory of choosing better tree species for greening in various enterprises. |
