- 摘要:
- 以30年前进行过带状皆伐带的保留带对采伐带内栽植形成的红松纯林、落叶松纯林、水曲柳纯林、云杉纯林林下土壤为研究对象,通过对皆伐带中间和边缘及保留带中间的土壤进行的分析,研究人工林对土壤物理性质的影响。结果表明:除了水曲柳中间的容重比天然林的高外,其余林下土壤的容重有所降低,降低幅度最大的是红松,影响最小的是云杉;红松人工林对于土壤孔隙的改良情况最佳,云杉的改良情况最差。
- Abstract:
- In 30 years ago after clear-cutting with retention zone on the cutting strip planting pure forest of Pinus koraiensis Sied.et Zucc.,and Larix olgensis Henry,and Fraxinus mandschurica Rupr.,and?Pinus koraiensis??Nakai as material,through the soil analysis of the middle and edge of clear-cutting strips and the middle of retained strips the its soil physical properties were studied.The results showed the soil bulk density of the middle of F.mandschurica was higher than that of the natural forest,the rest of the soil bulk density decreased,maximum reduction was?Pinus koraiensis?,minimum reduction was?Pinus koraiensis?.For the improvement of the situation of P.koraiensis plantation soil pore was the best,Pinus koraiensis??was the worst.
