| 摘 要： | 以关帝山华北落叶松人工林为研究对象,通过对不同强度间伐后林下植物群落调查,分析了抚育间伐对林下植被组成、物种多样性和水文生态特性的影响。研究结果表明,抚育间伐后林下植被草本植物的丰富度、多样性和均匀度都随抚育间伐强度的提高而增大,林下植被木本植物各指标都随抚育间伐强度的提高而减小,抚育间伐对林下植被草本植物的影响显著大于对林下木本植物的影响,各林分水分指示植物以潮润型为主,伐后林下潮湿型指示植物较未间伐林分增加;间伐后短期内灌木层的植物丰富度、多样性、均匀度都有所下降。

| Abstract: | This paper studied Larix principis-rupprechatii plantation in the Guandi mountain.Undergrowth were investigate and analyzed.The result showed that the richness,evenness index,and diversity index of herb layer were ranked in the order: heavy thinning>medium thinning>light thinning>CK after tending.Forest indicator with 3 degree after tending had an advantage in stand majored with 2 degree,which was opposite to shrub layer.Thinning had larger effects on herb layer. |
