摘　　要：为探究边缘效应对林区边缘地带生物多样性的影响,采用样方法获取山西省霍山七里峪的4个落叶阔叶林地和2个针叶林地样方,测量每个样方中灌木地上部分的鲜质量和干质量,计算其干质量与鲜质量之比,并记录落叶阔叶林和针叶林边缘特征种和指示种。结果显示:落叶阔叶林的灌木地上总生物量在林地边缘-5 m左右达到最大值26.57 kg;针叶林的灌木地上总生物量在林地边缘-5 m左右达到最大值3.58 kg。林地边缘不同区域的物种生物量不同,各物种生物量沿边缘表现为边缘±5 m区域>边缘-5 m以外区域>边缘5 m内区域。综上,研究结果对指导林区边缘地带的生态环境保护具有重要的参考价值。To explore the impact of edge effects on the biodiversity of forest margins, four samples of deciduous broad-leaved forests and two samples of coniferous forests in Qiliyu zone of Huo mountain in the Shanxi Province were obtained by sampling method. The fresh and dry mass of the above-ground shrubs in each quadrat were measured. The ratio of dry mass to fresh mass was calculated.The characteristic and indicator species on the margins of deciduous broad-leaved and coniferous forests were recorded. The results found that the total biomass of shrubs in the deciduous broad-leaved forests reached a maximum value of 26.57 kg at the edge of woodland edge(-5 m). The total biomass of shrubs in the coniferous forests reached a maximum value of 3.58 kg at the edge of woodland edge(-5 m). The biomass of different species was various in different areas at the edge of woodland. The biomass of different species at the woodland edge showed a trend: biomass at ±5 m area > biomass beyond-5 m area > biomass within 5 m area. In conclusion, the results have important reference value for guiding the ecological environment protection in the marginal zone of the forest area.
