| 摘 要： | 三峡库区消落带"冬水夏陆"的水文生态过程形成了典型的淹水-落干的干湿交替环境,在这种独特的环境变化下,土壤氮矿化也独具特色。综述了库区消落带在淹水-落干条件下土壤氮矿化特征,并分析了主要影响因素(包括土壤理化性质、生物因素、外源性有机物),提出了三峡库区消落带土壤氮矿化今后应关注的重点,主要从加强野外原位监测、分析不同类型消落带不同土壤类型时空变化特征、揭示土壤氮矿化影响机理及氮转化过程等方面深入开展研究。

| Abstract: | The water level fluctuation zone (WFLZ) in the Three Gorges Reservoir (TGR) undergoes an annually cyclic inundation and exposure due to the TGR operation, forming an unique dry and wet environments. The special environment leads to unique effect on soil nitrogen mineralization in the WLFZ. The paper summarized soil nitrogen mineralization characteristics under the condition of dry-wet cycle, and analyzed the main influence factors including soil physical and chemistry property, biological factors and exogenous organic matter. The paper suggested to carry out through studies on the following key points: enhancing field in-situ monitor; analyzing space-time characteristics of different soil types at nitrogen mineralization on different WLFZ; revealing influential mechanism on soil nitrogen mineralization and nitrogen transform process. |
