摘 要:通过查阅大量森林生态系统类型自然保护区土壤养分方面的研究资料,综述了环境因素及人为因素对保护区森林土壤养分的影响,并对森林类保护区土壤质量评价及土壤养分相关性的研究进行了概述,以期为森林类保护区土壤的深入研究及对其保护提供指导。森林土壤养分的分布存在显著的空间异质性特征,其最终分布格局是地形、植被、土壤类型、季节变化、土壤微生物等环境及人为因素共同作用的结果。在自然生态系统下,环境因素是土壤养分差异的主要决定因素。有效的人为管理方式能促进森林土壤养分的积累,而不当的干扰则会造成养分显著流失。对土壤质量进行准确评价,能够客观了解不同土壤管理措施对土壤的影响,有助于及时调整管理措施。在保护区建立森林土壤长期定位监测站,是全面掌握保护区森林土壤养分的影响因素及其影响机制的较好途径,最终为保护区森林的持续健康经营提供理论指导。Based on a large number of relevant literatures, the authors summarized the effect of environmentalfactors and human factors on forest soil nutrients in nature reserve, as well as the soil quality assessment andcorrelation of soil nutrients, to provide references for a deep research on forest nature reserve soil and itsprotection. The distribution of forest soil nutrients has significant spatial heterogeneity, and its finaldistribution pattern is the result of joint action of environmental factors, including topography, vegetation, soiltype, seasonal change as well soil microorganism, and human factors. In natural ecosystem, environmentalfactors are the main factors that determine the differences of soil nutrients. Effective human management canpromote the accumulation of forest soil nutrients, but improper interference will cause a significant loss of soilnutrients. Accurate soil quality evaluation can objectively clarify the impact of different soil managementpractices on soil, contribute to the timely adjustment of management measures. The establishment of long-termsoil monitoring stations in forest nature reserves is a good way to master the influencing factors and themechanism of forest soil nutrients, and can ultimately provide theoretical guidance for a sustainable andhealthy operation of forest nature reserve.
