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。
By reviewing a large number of research materials on soil nutrients in nature reserves of forest ecosystems, the effects of environmental factors and man-made factors on forest soil nutrients in protected areas were reviewed. The research on soil quality evaluation and soil nutrient correlation in forest protected areas The article is intended to provide an in-depth study of the soils of forest protected areas and provide guidance on their protection. The distribution of soil nutrient in forest has significant spatial heterogeneity, and its final distribution pattern is the result of the interaction of environment and human factors such as topography, vegetation, soil type, seasonal variation and soil microorganism. In natural ecosystems, environmental factors are the main determinants of soil nutrient differences. Effective man-made management can promote the accumulation of nutrients in forest soils, and undue interference will lead to significant loss of nutrients. Accurate evaluation of soil quality can objectively understand the impact of different soil management measures on soil and help to timely adjust management measures. The establishment of long-term monitoring stations for forest soils in protected areas is a good way to comprehensively grasp the influencing factors and influencing mechanisms of forest soil nutrients in protected areas and ultimately provide theoretical guidance for the sustainable and healthy management of the forests in the protected areas.
