| 摘 要： | 在辽宁省本溪市草河口镇设置固定标准地,观察不同间伐强度下杂木林的生长状况。结果表明:在中度间伐区内的杂木林生长良好,活立木蓄积生长率最大,其他依次为弱度间伐区、对照区和强度间伐区。强度间伐区内的草本和木本植物多样性最高,对照区、中度间伐区次之,弱度间伐区最低。从土壤理化性质改良效果来看,弱度间伐区最好,对照区、中度间伐区次之,强度间伐区最低。

| Abstract: | The monumented sample was set in the Caohekou town Benxi city Liaoning province and looking into the growth in the different thinning intensity.After analysis,the shaw in the mid-thinning intensity grows well and its rate of stand volume was largest,then it was,and high-thinning.the plant diversity of herbage and wood in high-thinning was the largest,then it was contrast,mid-thinning and ebb-thinning.For improving effect of physicochemi-property,ebb-thinning was the best,and then it was contrast,mid-thinning and high-thinning. |
