| 摘 要： | 桉树是保障我国木材产业的重要树种,在产生巨大社会及经济效益的同时,桉树造林所引发的生态环境问题不容忽视。综述了桉树林地土壤物理性状、养分和微生物群落发生变化的成因,桉树自身水分消耗特征、土壤容重和孔隙度的变化、林下植被和枯枝落叶以及连栽和炼山等人为生产经营活动,是导致桉树造林过程中林地土壤物理性质变化的重要原因;桉树自身对养分的需求量大、连栽、炼山、翻耕、除草、轮伐以及营造桉树人工混交林、土地利用类型转变是导致桉树造林过程中林地土壤养分变化的重要因素;桉树造林对林地土壤理化性质的影响、凋落物分解和根系分泌物释放以及炼山、翻耕、间伐和施肥等管理行为,都直接或者间接地影响林地土壤微生物群落。通过对桉树造林过程中维护和提升土壤生态系统服务功能的相关措施进行展望,旨在为推进我国现阶段桉树产业可持续发展提供理论参考。

Research Progress in Effects of Eucalyptus Plantation on Soil Physical Properties, Nutrients and Microbial Community |

| Abstract: | At present, Eucalyptus is one of the most important species for wood industry in China. Eucalyptus plantation has been producing great social and economic benefits, however, the ecological and environmental problems caused by Eucalyptus plantation should not be ignored. This paper briefly summarizes the causes of changes in Eucalyptusplantation soil physical properties, nutrients and microbial community as follows: first, water consumption characteristics of Eucalyptus, changes of soil bulk density and porosity, undergrowth vegetation and litters, successive planting, controlled burning and other man-made production and operation activities are important reasons for the changes of soil physical properties within the period of Eucalyptus plantation; second, a large demand for nutrients by Eucalyptus, successive planting, controlled burning, ploughing, weeding, rotation cutting, and creating a good intercropping models of Eucalyptus and other plants, changes of land use types are important factors causing the changes of soil nutrient contents in Eucalyptusforest; third, changes in soil physical and chemical properties due to Eucalyptus plantation, litters decomposition and root exudates release as well as management behaviors such as controlled burning, ploughing, intermediate cutting and fertilization directly or indirectly affect soil microbial community. Finally, some measures to maintain and enhance the service function of soil ecosystem during the Eucalyptus plantation are prospected with a view to provide a theoretical basis for promoting the sustainable development of Eucalyptus industry in China. |
