| Research Abstract |
Floodplain forestation in a river channel increases the risk of floods and also deteriorates the original ecosystem. The soil of a floodplain is usually sterile and has very limited in nitrogen content. Therefore, plant succession in the floodplain is largely governed by the availability of soil nitrogen. The nitrogen pool in the floodplain soil expands due to atmospheric fallout and microbial N-fixation. However, the nitrogen enrichment in soil and its processing at the plant-soil interface is often intervened by the flooding events. After evaluating these processes, the prediction model of the plant succession was developed.
