| 摘 要： | 通过在江西省红壤地区主要林区的铜鼓县和德兴县选择不同林龄（1～28年）的杉木人工林样地采用随机网格法对土壤分层取样，并对土壤样品进行分析后的研究结果表明，从造林阶段到5～8年的幼林期，包括林地凋落物层、土层厚度、有机质、全N、CEC、BS、pH和速效N、P、K在内的林地主要土壤质量性状大幅度退化。随着树龄的增大，林地土壤质量性状开始缓慢恢复。但是，即使杉木人工林进入了主伐期，土壤质量性状的恢复程度仍选低于其初始水平。 |

| Abstract: | Soil fertility quality properties were studied by random gridding sampling and analyzing of soils at artificial Chinese fir forest sites with different tree ages in T onggu County and Dexi County, which are majortimber producers in the red soil region of Jiangxi Province.Properties, including litter layer, soil depth, organic matter, total N, CEC, BS, pH and available N, P, K, degraded sharply during the first 6-8 yeas after forestation.With increase in tree ages, these properties recovered slowly.But they were far below their initial levels even when the forests reached their mature stage.This paper concluded that soil fertility quality degradation is unavoidable under the current forestry management practices, and that improving forestation and reforestation methods, establishing proper soil management practices mainly aimed at protecting surface soil under seedling tree, and increasing input to forest soil, are key measures to keep soil quality from degradation. |
