皖西地区马尾松枫香混交林效益研究

Study on Ecological Effects of Mixture Plantation of Masson Pine and Sweetgum in Western Anhui Province

马尾松枫香混交林较人工马尾松纯林食物链复杂，生物多样性增加，自我调节能力增强，较有效地抑制松毛虫虫害的发生和蔓延，林下舒适度宜人，观赏价值提高。林冠对降水截持量增加，有效地减轻水土流失。提出营造马尾松枫香混交林是皖西水土流失严重、自然景观优美地区展开森林旅游，进行低产林改造的好方法。

The mixed forest of masson pine and sweetgum produced an ecologically stable population structure.The stand volume from mixed forest was 30%50% higher than that from pure masson pine stand.Dendrolimus punctatus was effectively controlled and soil erosion reduced under the condition of mixed plantation of the two species.
