摘  要：
为了解硒元素在大庆市龙凤湿地环境—植物系统中的分配特征,于2011年春季采集了龙凤湿地土壤、水、芦苇3种样品,采用原子吸收光谱法测定其中硒含量,应用统计学方法分析了3者之间的关系。结果显示,龙凤湿地土壤硒含量均值介于129.63～142.18μg/kg,水硒含量在3.87～7.02μg/kg,芦苇根、茎、叶硒含量分别为50.17,18.29,和15.68μg/kg。经分析表明,土壤硒含量与芦苇硒含量之间存在显著正相关关系,并且芦苇对环境硒的富集能力较弱,属非富硒植物。

摘  要：
In order to understand the characteristics of selenium(Se) distribution for environment-plant system in the Longfeng wetland of Daqing City,soil,water and reed were collected in the spring of 2011.The content of Se was measured using hydride generation-atomic absorption spectrometry(HGAAS) and the relationship among the three samples was analyzed by statistical methods.Results show that the content of Se in soils was 129.63~142.18 μg/kg,the mean of water Se content was 3.87~7.02 μg/L,and the contents of Se for reed root,stem and leaf were 50.17,18.29 and 15.68 μg/kg,respectively.The results show that there was a significant positive correlation in content of Se between soil and reed.Reed enrichment in Se from the environment was weak,and thergfor was a non-enriched Se plant.
