摘要: 通过对帽儿山7种典型森林类型(示范区)植被恢复的调查,以生物多样性为研究对象,应用主成分分析、典型相关分析的方法,对各示范区恢复情况进行评分,并分析示范区植被恢复效果与影响因素之间的关系。结果表明:恢复时间、采伐方式对生物多样性的恢复和分布起主导作用,示范区Ⅵ(白桦-水曲柳混交林)营造樟子松与水曲柳带状混交林的恢复效果最好,示范区Ⅶ(白桦-山槐混交林)恢复效果次之。研究结果为森林生物多样性恢复方式的选择提供决策支持。

Abstract: This article studied seven typical forest types(demonstration areas)in the Maoer Mountainous Region. Taking biodiversity as the criterion, using principal component analysis and the CCA methods, this study analyzed the relationship between the restoration condition and environmental factors. Results showed that harvesting method is the dominant factor affecting the restoration of biodiversity. Among the sites studied, demonstration area Ⅵ (Betula platyphylla-Fraxinus mandshurica mixed forest) showed the best restoration results where Fraxinus mandshurica and Pinus sylvestris var. mongolica belt-shaped mixed forest is developed, followed by demonstration area Ⅶ (Betula platyphylla-Maackia amurensis mixed forest). The study results provide supports for the management decision of the optimized biodiversity restoration techniques in the region.

Key words: biodiversity, forest type, restoration result
