对辽东山区生态公益林进行抚育间伐效果研究表明:间伐11a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.
對遼東山區生態公益林進行撫育間伐效果研究錶明:間伐11a後,矇古櫟林中度間伐區林分平均胸徑生長率最大;雜木林弱度間伐區林分平均胸徑生長率最大.矇古櫟林和雜木林的蓄積生長率均是中度間伐區最大.矇古櫟林中度間伐區葉麵積指數最大;雜木林弱度間伐區葉麵積指數最大.林下植物生物量以中度間伐區最大.間伐提高瞭矇古櫟林、雜木林的凋落物儲量和最大持水量及林分土壤的持水能力,其中以中度間伐區最明顯.

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 and weed tree forest after medium thinning. The Q. mongolica forest after medium thinning and the weed tree forest after light thinning exhibited the highest leaf area indexes. Thinning has a significant effect on improving the amount and maximum moisture capacity of the litter and the water holding capacity of the soils in the Q. mongolica forest and weed tree forest, especially for the medium thinning.
