摘　　要：沉积物氮矿化在水生态系统氮循环中扮演着重要作用,是氮循环中重要的一环,影响着生态系统的生产与稳定。通过总结现阶段湖泊沉积物氮矿化的研究现状和影响因素,分析沉积物的固有特性、环境因子、水生生物对沉积物氮矿化的影响,指出沉积物有机质与氮矿化关系密切,且是今后沉积物氮矿化的研究热点。Sediment nitrogen mineralization plays an important role in the nitrogen cycle of aquatic ecosystems,which is an important part of nitrogen cycle affecting its production and stability.This article summarizes the current research status and influencing factors of nitrogen mineralization in lake sediments,analyzes the influence of factors including the inherent characteristics of sediments,environmental factors,aquatic organisms on sediment nitrogen mineralization.And it points out that there is a close relationship between organic matter and sediment nitrogen mineralization,which would be a hotspot on sediment nitrogen mineralization in the future.
