| 摘 要： | 对小兴安岭5类典型泥炭沼泽土壤水分物理性质进行对比研究,结果表明:落叶松-杜香-泥炭藓沼泽土壤容重最小,非毛管孔隙最高,持水性最好;漂筏苔草沼泽和油桦-笃斯越桔-修氏苔草沼泽次之,修氏苔草沼泽和白桦-油桦-小叶章沼泽相对较差.落叶松-杜香-泥炭藓沼泽0～40 cm平均土壤容重为0.06g·cm-3,非毛管孔隙31.69%,总孔隙度高迭87.19%,平均土壤质量含水量、最大持水量、毛管持水量和最小持水量分别为1130.1%、1586.57%、1007.71%和882.70%,是对照林地的56.6倍、26.4倍、24.9倍和25.5倍.在5类泥炭沼泽中,白桦-油桦-小叶章沼泽0～40 cm平均土壤容重最高(0.74 g·cm-3),总孔隙度最低(62.02%),土壤各持水指标均最小,但其持水指标均显著高于对照林地. |

| Abstract: | Soil water physical features of five kinds of typical peat swamps were compared in Xiaoxing'anling Mountain,and the following results were obtained.The Larix gmelinii-Ledum palustre-Sphagnum swamp had the least soil density,the highest non-capillary porosity and the optimum water holding,and the Carex pseu-docuraica swamp,the Betula ovalifolia Ruprecht-Vaccinium uliginosum-Carex schmidtii swamp,the Carex schmidtii swamp,as well as the Betula platyphylla-Betula ovalifolia Ruprecht-Deyeuxia angustifolia swamp... |
| Keywords: | Xiaoxing'anling Mountain peat swamp soil bulk density porosity water retention |
