摘　　要：为进一步探明潜流带表层沉积物对地表水体的"源汇"关系及季节性转化规律,综合阐述了当前国内外在河道和湖泊潜流带方面的研究进展,包括不同区域潜流带内水流形态及其对氮素运移转化的影响机制、潜流带内部环境变化梯度和温度分布季节性变化对潜流带好氧-厌氧区分布范围及氮素硝化反硝化过程的影响、潜流带中氮素与地表水体的交换特征及季节变化规律,并结合当前的研究动态提出了潜流带水流特性及氮素运移转换研究中存在的问题并对研究进行展望。To better illuminate the relationship of surface sediment in hyporheic zones as a source or sink for surface water and its seasonal conversion rule, this review focuses on research advances in hyporheic zones of rivers and lakes in China and other countries. The main aspects of the review include the water regimes of hyporheic zones and their influence on the transport and transformation of nitrogen, the influence of interior environmental gradients and seasonal variation of the temperature distribution in hyporheic zones on the distributions of aerobic and anaerobic zones and the processes of nitrification and denitrification, and the exchange characteristics and seasonal variation patterns of nitrogen in hyporheic zones with surface water. Some research prospects are proposed based on present research trends and deficiencies in hyporheie zones.
