人工林更新对土壤物理、化学和生物学特性有着不同程度的影响,但影响程度与造林方式、树种、整地、林龄、施肥等因素密切相关。针对目前研究中存在的不足,今后的研究工作需要将对比分析研究、时间序列的研究、重复采样研究和模拟研究4种方法有机地结合起来,开展人工林土壤质量变化机理的研究,以期为科学营造和管理人工林,提高林地生态效益和经济效益提供科学依据。
Plantation regeneration has different impacts on soil physical, chemical and biological characteristics, but the degree of impact is closely related to afforestation methods, tree species, site preparation, age, fertilization and other factors. In view of the shortcomings in the current research, the future research work needs to combine the four methods of comparative analysis, time series, repeated sampling and simulation studies organically to study the mechanism of soil quality change in plantation so as to be a scientific To create and manage artificial forests, improve the ecological benefits and economic benefits of woodland to provide a scientific basis.
