摘要/Abstract

摘要： 根据对人工营造20年生阔叶红松林典型样地的调查,分析了人工阔叶红松林的生产力、植物多样性及其相互关系.结果表明,人工营造的20年生红松-白桦、红松-色赤杨、红松-水曲柳混交林林地生产力分别达.529、4.9和5.82 t·hm^-2·yr^-1,高于同龄人工红松纯林(3.812 t·hm^-2·yr^-1);而红松-刺楸、红松-紫椴混交林分别为2.945和2.84 t·hm^-2·yr^-1,低于人工红松纯林.人工阔叶红松林乔木层、灌木层、草本层植物多样性均高于红松纯林;红松纯林内的植物种数仅为人工阔叶红松混交林的42%～52%,植物总数量也只有混交林的11%～37%.人工营造阔叶红松林是迅速恢复、发展顶极阔叶红松林的一种有效措施,但要经历相当长的时间和人为的不断调控.

Abstract: An investigation in the typical plots of 20-yr artificial broad-leaved Korean pine forests in eastern Liaoning mountainous areas showed that the productivity of mixed forests Pinus koraiensis-Betula platyphylla,P.koraiensis-Alnus tinctoria,and P.koraiensis-Fraxinus mandshurica was 6.529,4.966 and 5.682 t·hm^-2·yr^-1,respectively,much higher than that of pure Korean pine forest (3.812 t·hm^-2·yr^-1),while mixed forests P.koraiensis-Kalopanax septemlobus and P.koraiensis-Tilia amurensis had a productivity of 2.945 and 2.84 t·hm^-2·yr^-1,respectively,lower than that of pure Korean pine forest.The plant species diversities of arbor,shrub and herb layers of artificial broad-leaved Korean pine forests were all higher than those of pure Korean pine forests.The plant species number in pure Korean pine forests only accounted for 42%～52% of artificial broad-leaved Korean pine forests,and the tree number of vegetation only accounted for 11%～37% of mixed forests.These results suggested that artificial broad-leaved Korean pine forests could provide the chances for the succession of secondary forest systems to regional climax,but it would take a long time to reach the climax.
