抚顺市大气重金属污染的植物监测与分析研究

Research on Plant Monitoring and Analysis of Fushun Heavy Metal Pollution in Atmosphere

采用生物富集原理,利用松针对抚顺地区大气中重金属元素的分布情况进行了监测与分析,结果表明:抚顺地区三种不同的松树对不同金属元素的富集能力是不同的,总体上看沙松的富集能力略高于油松和落叶松;工业区、交通干道和居民区松针中富集的金属含量高于农村地区;从不同的海拔高度上来看,在500米以下的低空大气中金属元素的分布量比高海拔地区高;不同金属元素间存在一定的相关关系。

Based on biological enrichment principle, the distribution of heavy metal in atmosphere of Fushun was tested by pine needles. The results showed that the enrichment ability for different metal elements of the different pine was different. The enrichment ability of abies holophylla was slightly higher than pinus tabulaeformis and larix. The metal content of pine needles in areas around industrial zones, traffic artery and residential areas were higher than in rural areas. From the perspective of different altitudes, low - level atmosphere below 500 meters contains more metallic elements than higher altitudes. There is certain degree of correlations between different metal elements.
