| 摘 要： | 本文运用对比方法研究了江西省境内亚热带天然次生阔地及其砍伐迹地炼山营造杉木林后土壤系统养分状况的变化,结果表明:炼山营造杉木林使土壤系统功能恶化,土壤肥力急剧衰退.据此,本文对亚热带地区造林技术之现状提出质疑,认为,以炼山营造杉木林的方式更新阔叶林砍伐迹地不宜继续进行。

| Abstract: | This paper deals with the changes of nutrient status of the soils of broad-leaved for-est and Chinese-fir forest which were afforested over the broad-leaved forest cut slash af-ter control-burning in Jiangxi Province,China.The results show that the control-burn-ing to afforest Chinese-fir deteriorates the functions of soil ecosystem and declines soilfertilily.So it is advised in the paper that it is inapplicable to reforest the broad-leavedforest cut slash with Chinese-fir by using the control-burning. |
