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.
