| 摘 要： | 以三江平原的3种主要沼泽类型——小叶樟沼泽、乌拉苔草沼泽、毛果苔草沼泽为研究对象,对其土壤和植物中的总硫质量分数及水中硫酸盐质量分数进行分析。3种沼泽土壤总硫质量分数的顺序为小叶樟沼泽(622.4 mg/kg)<乌拉苔草沼泽(820.5 mg/kg)<毛果苔草沼泽(1022.4 mg/kg);植物总硫质量分数的顺序为小叶樟(1638.5 mg/kg)<乌拉苔草(1796.9 mg/kg)<毛果苔草(1892.8 mg/kg);水中硫酸盐的质量分数为小叶樟沼泽(1.69 mg/kg)<乌拉苔草沼泽(1.81 mg/kg)<毛果苔草沼泽(2.00 mg/kg)。并探讨了典型湿地生态系统中硫质量分数的影响因素。

| Abstract: | Three important marsh types including Calamagrostis angustifolia marsh, Carex lasiocarpa marsh and Carex meyeriana marsh were studied in this paper. The total sulfur in these soils and plants, and sulfate in water were analyzed. The order of the total sulfur in the soils of three marshes was Calamagrostis angustifolia marsh (622.4 mg/kg) < Carex meyerianan marsh (820.5 mg/kg) Carex lasiocarpa marsh (1022.4 mg/kg), the order of the total sulfur in the three plants was Calamagrostis angustifolia (1638.5 mg/kg) < Carex lasiocarpa (1796.9 mg/kg) < Carex lasiocarpa (1892.8 mg/kg), and the order of sulfate in water was Calamagrostis angustifolia marsh (1.69 mg/kg) < Carex meyerianan marsh (1.81 mg/kg) < Carex lasiocarpa marsh (2.00 mg/kg). At last the factors affecting sulfur in the typical wetland ecologies were discussed. |
