摘要
以河南省济源市大沟河林场营造的栓皮栎人工公益林凋落物为研究对象,采用样地随机布置凋落物收集框的方法来收集凋落物,并对数据进行统计分析,结果表明:①在2006年9月—2007年5月,20,30,40年生栓皮栎的凋落物输出量分别为5 594,8 358,6 397.6 kg/hm2.②在20,30,40年生栓皮栎人工林凋落物的对比中,凋落物总量比较为30年生(8 358 kg/hm-2)>40年生(6 397.6 kg/hm2)>20年生(5 594 kg/hm2).③凋落量动态随季节变化明显,其凋落量的季节变化为秋季>春季>冬季,凋落量的峰值出现在10,11,12月,主峰在11—12月.
Taking litterfall for artificial public welfare of the Quercus variabilis Blume in the Henan province Jiyuan city big brook tree farm as research,useing the type place stochastic arrangement to wither and fall the collection frame＇s method to collect withers and fails and monitoring data, the results show as a follow： ①From September, 2006 to May, 2007, the falling output of the 20, 30 and 40 years Quercus variabilis Blume is 5 594, 8 358, 6 397.6 kg/hm^2. ②The forest weakly falling contrast of 20,30 and 40 years fresh Quercus variabilis Blume planted is, total quantity of the weakly falling is 30 years lives （8 358 kg/hm^2）〉40 years lives （6 397.6 kg/hm^2）〉 20 years lives （5 594 kg/hm^2）. ③The quantity dynamical of weakly failings is obviously along with the seasonal variation, the seasonal variation for the quantity of the weakly failings is： the autumn〉 the spring〉 the winter, litter production both peaked in October, November and December with the highest in November and December.
