| 摘 要： | 为了进一步明确煤粉尘的沉降特征及其对植物抗逆系统的影响，笔者通过室外定期收集降尘及室内植物生理指标分析等方法，研究了孝义市梧桐镇某焦化厂储煤场周围下风向400 m范围的总降尘和煤粉尘的沉降规律，及其煤粉尘对该范围内所种植苗期玉米抗氧化系统的影响。结果表明，随着距储煤场距离的增加，总降尘和煤粉尘的量显著减少，而苗期玉米叶片的总抗氧化能力（T-AOC）、双氧化物岐化酶（SOD）、脱氢酶（CAT）、丙二醛（MDA）也均显著降低，尤其是SOD酶活性表现更为敏感。总之，煤粉尘的降落促进了玉米体内抗逆系统的防御能力，因而导致T-AOC、SOD、CAT抗氧化指标的增加，减少了对玉米的氧化伤害。

| Abstract: | In order to further clarify the deposition law of coal dust and its effects on antioxidant system of the plants,effects of coal dust from the coal storage area of a coke oven plant in Taiyuan on antioxidant system of the surrounding maize within 400 m range were investigated,under outdoor coal dust was regularly collected and indoor plant physiology index analysis.Results indicated quantities of total dust and coal dust in the distance apparently decreased with away from the coal storage area.Moreover,the a... |
