| 摘 要： | 在立地条件较差的陡坡山地进行丛状造林,可以充分利用一切可以利用的山地,提高造林的成活率和保存率,迅速恢复森林的生态环境。通过对红松(Pinus koraiensis Sieb.et Zucc.)陡坡丛状造林效果的研究分析,结果表明,陡坡丛状造林以3株一丛或5株一丛为宜,在不易发生水土流失的林地,初植密度以4 400株.hm-2为宜;立地条件较差,坡度较陡,易发生水土流失的林地,以6 600株.hm-2为宜;丛状造林保存率能达到70%以上,蓄积量比对照区提高38%～50%。

| Abstract: | Massive planting which were conducted on steep slopes of mountain under poor site conditions;taking full advantage of the mountain not only can improve the survival & preservation rate,but also can quickly restore the ecological environment of the forest.Through analysis of massive plant effect on steep slopes for Pinus koraiensis,result shows that:massive planting on steep slopes being three or five trees a clump is suitable;on the forestland without soil and water losses,initial planting density should appropriately be 4 400 trees·hm-2;on the forestland with soil and water losses,poor site conditions,steep slope,initial planting density should appropriately be 6 600 trees·hm-2;preservation rate of massive planting can reach more than 70%,and its stock volume increase by 38%-50% than that of the control area. |
