| 摘 要： | 不同草甸植被下土壤有机质含量变化在70.0～122.8gkg-1之间,同时,腐殖质特性亦存在较大差异。采用熊田法研究表明,可提取腐殖质中胡敏酸所占比率为47.99%～56.98%,游离胡敏酸(fHA)比率为51.67%～60.10%,游离富里酸(fFA)比率为80.01%～86.46%;此外,不同草甸植被下土壤腐殖质的相对色度(RF),E4也有明显差异。

| Abstract: | Soil organic matter content and humus properties were different under different meadow vegetations. The total organic matter content varied from 70.0 to 122.8g/kg. According to Tsutsukis method, the ratio of HA/HA was from 51.67% to 60.10%, the radio of FA/FA was from 80.01%to 86.46%, and the HA was from 47.99% to 56.98% of the total extractable humus. The RF as well as E_4 of the humus was also significantly different under different meadow vegetations. |
