摘  要：
在2002年开展抚育的6 a生刺槐林中布设样地,以未抚育处理为对照,对抚育当年、4 a后(2006年)、8 a后(2010年)和12 a后(2014年)林地枯落物层的持水能力进行研究,结果表明:随着林木的生长,抚育样地和对照样地枯落物层的最大持水量和最大持水率均呈现梯度升高趋势,而抚育样地升高幅度更明显。抚育当年与4a后,抚育样地与对照样地的枯落物层最大持水量和最大持水率相比较均无显著性差异;抚育8 a后,两者差异达到显著水平(P<0.05);抚育12 a后,两者差异达到极显著水平(P<0.01)。抚育能够有效提高林地枯落物层的最大持水量和最大持水率。

摘  要：
The forest land litter layer water holding capacity was researched after tending in the very year,4 years( 2006) 、8 years( 2010) and 12 years( 2014). The sample plot was laid in 6 years Robinia pseudoacacia forest which was tended in2002. The no tending treatment was chosen as the control. The result showed that the maximum water holding capacity and water holding ratio of litter layer of tending and control sample plot presented gradient rise trend along with the growth of forest wood while the ascending range of tending sample plot was more obvious. There was no significant difference with maximum water holding capacity and water holding ratio of litter layer of tending and control sample plot after the very and 4years. The difference reached significance level after tending 8 years. Furthermore,it achieved extreme significance level after tending 12 years. The forest land litter layer maximum water holding capacity and water holding ratio can be raised effectively by tending.
