摘要
监测结果表明，营造山桂花、西南桦、马尖相思、高阿丁枫四树种的人工纯林及其混交林数年后，对土壤pH值和交换性能等，一般无不良影响，与天然林相近甚至略优。其中，效果较好的林分类型有：西南桦×马尖相思、西南桦×肉桂等，效果最差的是高阿丁枫×西南桦。
Accordng to the investigation data relevant to soil characteristics on pure plantation forest of Cinnamomum cassia, Betula alnoides, Acacia mangium, Altingia excelsa and mixture forests consisted of every 2 species afforementioned for several years, the results showed that these types of stands almost had no influences on pH value and exchange function of forest. The influences on forest soil close to or better than that of natural forests.Among which the stands with better effect are Betula alnoide×Acacia mangium, Betula alnoide×Cinnamomum cassia, the worst stand is Altingia excelsa×Betula alnoides.
