|
摘要
于2014年3月20日,分别在中国科学院三江平原沼泽湿地生态试验站内碟形洼地的漂筏薹草(Carex pseudocuraica)+芦苇(Phragmites australis)群落、毛薹草(Carex lasiocarpa)群落、乌拉薹草(Carex meyeriana)群落和沼柳(Salix brachypoda)+小叶章(Calamagrostics angustifolia)群落区中,采集了0～50 cm深度的土壤样品,测定土样的全铁含量,分析其影响因素。研究结果表明,0～50 cm深度土壤中的全铁质量比为16 398.06～36 152.33 mg/kg;在水平方向上,由碟形洼地中心到边缘方向,0～50 cm深度土壤中全铁含量的平均值逐渐增大,漂筏薹草+芦苇群落区土壤中的全铁含量平均值最小,为21 318.37 mg/kg,沼柳+小叶章群落区土壤中的全铁含量的平均值最大,为25 375.56 mg/kg;在垂直方向上,各植物群落区土壤中的全铁含量最大值都出现在30～40 cm深度,最小值都出现在0～10 cm深度;在20～40 cm深度,随着土壤深度增加,土壤中的全铁含量逐渐增大;土壤有机质含量是研究区土壤全铁含量的主要影响因素。
In order to clarify distribution characteristics of total iron contents in the soils with Carex pseudocuraica+ Phragmites australis community, Carex lasiocarpa community, Carex meyeriana community, and Salix brachypoda+Calamagrostics angustifolia community in saucer depression in Sanjiang Plain Experimental Station of Wetland Ecology, Chinese Academy of Sciences, soil samples at 0-50 cm depths were taken on March 20, 2014, and influencing factors were analyzed. The results showed that the total iron contents in soil of 0-50 cm depth were 16 398.06-36 152.33 mg/kg. In the horizontal direction, from the center to the edge of the saucer depression, the average of total iron contents in soil of 0-50 cm depths increased gradually. The highest was 25 375.56 mg/kg occurred in Salix brachypoda + Calamagrostics angustifolia community area,and the lowest was 21 318.37 mg/kg occurred in Carex pseudocuraica+ Phragmites australis community area. In the vertical direction, the highest of total iron contents in each community area occurred in soil of 30-40 cm depths, the lowest of total iron contents occurred at 0-10 cm depths. With soil depth increasing, total iron contents in soli increased gradually at 20-40 cm depths. Organic matter content in the soil was the main influencing factor for total iron contents in the soil in the study area.
