| 摘 要： | 对辽东山区生态公益林进行抚育间伐效果研究表明:间伐11 a后,蒙古栎林中度间伐区林分平均胸径生长率最大;杂木林弱度间伐区林分平均胸径生长率最大。蒙古栎林和杂木林的蓄积生长率均是中度间伐区最大。蒙古栎林中度间伐区叶面积指数最大;杂木林弱度间伐区叶面积指数最大。林下植物生物量以中度间伐区最大。间伐提高了蒙古栎林、杂木林的凋落物储量和最大持水量及林分土壤的持水能力,其中以中度间伐区最明显。 |

| Abstract: | A survey was conducted to study the effects of thinning on non-commercial forests in the eastern mountainous region of Liaoning Province by setting up sample plots in a Quercus mongolica forest and a weed-tree forest.The highest growth rates of diameter at breast height were found in the Q.mongolica forest 11 years after medium thinning and in the weed-tree forest after light thinning,while the highest growth rates of volume and biomass of undergrowth plant species were observed in both Q.mongolica forest a... |
