天然次生针阔混交林不同定株抚育强度下林木生长状况差异研究
Study on the Differences of the Growth Status of Natural Secondary Coniferous and Broad-Leaved Mixed Forest Under Different Tending Intensity of Singling
摘要
Abstract
In the case of forest stand,canopy densities and stand age under the similar conditions,forest tending to natural secondary coniferous and broad-leaved mixed forest were carried out according to different tending intensity of singling 5％,10％,15％,20％,25％.The difference of DBH growth between the plots mainly came from the tending intensity of 5％,10％ and 15％.When the tending intensities was more than 15％,increasing the tending intensities did not significantly increased the growth of DBH.Raising the tending intensities had no significant effects on the growth of the tree height.Increasing the intensities of tending can further increase the growth of tree volume,but when the tending intensities reaches a certain level (15％),increasing tending intensities can't increase the growth of tree volume significantly.关键词
