摘要：混交林凭借其较高的生物多样性和复杂的结构特征,在改善土壤质量、增强碳储存和提高生态系统功能方面具有明显优势,因此实施速生纯林混交化改造是应对土壤肥力退化的有效途径。团聚体作为土壤的基本单元,能够反映土壤健康状态的细微变化。由于混交林内部生物和环境因子的复杂关系,速生纯林混交化改造对团聚体特性的影响因素缺乏系统梳理。文中综述混交林与纯林在土壤团聚体稳定性、团聚体养分特征和固碳能力方面的差异,探讨混交林如何通过改善凋落物质量和微生物活性促进土壤团聚体的稳定性和养分有效性进而增强土壤的固碳潜力,并从3个方面对未来混交人工林团聚体特性研究进行展望,以期为实现人工林可持续经营提供理论依据。
Mixed forests,with their higher biodiversity and complex structural characteristics,demonstrate significant advantages in improving soil quality,enhancing carbon storage,and improving ecosystem functions.Therefore,the conversion of fast-growing pure forests to mixed forests is an effective approach to curb soil fertility degradation.Aggregates,as the basic units of soil,are capable of reflecting subtle changes in soil health.Due to the complex interactions between biological and environmental factors within mixed forests,few studies have been conducted for analyzing the factors influencing aggregate characteristics in the conversion process to mixed forests.This paper reviews the differences between mixed forests and monocultures in soil aggregate stability,aggregate nutrient characteristics,and carbon sequestration capacity.It further explores how mixed forests can enhance aggregate stability and nutrient availability by improving litter quality and microbial activity,thereby increasing the soil’s potential in carbon sequestration,and discusses the directions of the future research on soil aggregates characteristics in mixed planted forest from three perspectives,aiming to provide the theoretical basis for the sustainable management of planted forest.
