摘要: 人工林碳汇在全球碳循环及温室气体减排中发挥着重要作用。人工林是处于人为调控下的生态系统类型,经营管理措施是影响人工林土壤碳平衡的重要因素。通过科学合理的生态系统管理,增强人工林的土壤碳汇,对减缓气候变化具有十分重要的意义。本文综述了主要经营管理措施(造林树种、轮伐期、采伐、灌溉和施肥)对人工林土壤碳储量与碳通量影响的研究进展,结果表明:人工林经营管理措施可通过改变林地的温度、水分、养分和土壤结构,来影响土壤有机碳储量和土壤呼吸等碳循环过程。但目前人工林管理对土壤碳影响的研究还很不足,一些营林措施还未展开相关研究。未来应针对人工林管理措施对土壤碳的影响做更全面的定量研究。

Abstract: Forest plantation carbon sink plays an important role in the global carbon cycle and the reduction of greenhouse gases emission, while management practice is an important factor affecting the soil carbon balance of forest plantations. Appropriate ecosystem management can improve the soil carbon sequestration of forest plantations, being of great significance in mitigating the impact of climate change. In this paper, the research advances on the effects of main management practices, e.g., species selection, rotation period, cutting, irrigation, and fertilization, on the soil carbon stock and soil CO2 efflux of forest plantations were reviewed. These practices could impose great effects on the soil carbon stock and soil respiration via regulating soil temperature, soil water content, soil nutrient contents, and soil structure. However, up to now, the researches on the effects of management practices on forest plantation soil carbon have not been adequate, and some of the management practices have not been examined yet. Therefore, more comprehensive and quantitative researches on the effects of management practices on forest plantation soil carbon should be further made.
