摘要:在29 a生1代杉木林采伐迹地上用5种林地处理方式进行2代杉木人工林营造,并研究处理后3 a土壤体积质量、pH值、有机质的变化。结果表明:BL3BM0(收获树干和树皮、加倍采伐剩余物)处理方式对降低土壤体积质量和提高土壤pH值的作用最大,是最佳的立地管理措施,而BL0BM0(收获地上所有有机质)处理的作用正相反,增加土壤体积质量和降低土壤pH值的幅度最大,对土壤肥力的维持最为不利。火烧采伐剩余处理并非最差的立地管理方式。

Abstract: The second-rotation Chinese fir (Cunninghamia lanceolata) plantation was established with 5 kinds of site management treatments on the cleared area of a 29-yrea-old first-rotation Chinese fir plantation. And 3 years after treatments, changes of soil bulk density, pH value (H2O) anic matter were studied. The results showed that: ‘double slash’ treatment (BL3BM0), which decreased soil bulk density and increased pH value the most, was the best measures for site management. In contrast, the ‘removal of all anic matters’ treatment (BL0BM0), which increased soil bulk density and decreased pH value the most, had th
