不同抚育强度对米槠生长过程的影响

摘要

对梅列区不同抚育强度米槠林标准木的胸径、树高和材积生长情况进行分析，结果表明抚育强度影响米槠胸径、树高、材积的生长过程，抚育强度越大，米槠胸径、树高、材积的生长高峰来得越早，胸径总生长量随着抚育强度的增大而增大，树高和材积总生长量均表现为中度抚育>强度抚育>对照>弱度抚育。%The growth of diameter at breast height,height and volume with different tending intensity was studied. The results show that tending intensity effects the growth of diameter at breast height,height and volume. The higher the tending intensity,the peak of diameter at breast height,height and volume comes sooner. The total growth of diameter at breast height is higher when the tending intensity is greater. The total growth of height and volume is the most high in the middle tending forest,the second in the great tending forest,the third in the compared forest,and the last in the least tending forest.
