Succession of bacterial community structure and function in wetland soil under drought and flooding

The metabolic activity of bacteria and their responses to the changes of water status may greatly influence the ecological functions of wetlands. However, few people consider the changes of soil function and bacterial community under drought and flood conditions. Soil was collected from a typical seasonally flooded wetland transect on the Bang Lake basin . The collected soil was packed into 15 pots in January 2015 and five moisture gradients were conducted to simulate the hydrological conditions of the Lake wetland. Soil samples were collected at the 1, 21, 132 d were conducted to the bacterial community composition analysis.

细菌的代谢活性及其对水分状况变化的响应，可极大影响湿地的生态功能。然而，目前鲜有研究关注干旱与淹水条件下土壤功能及细菌群落的变化。本研究的土壤样品采集自邦湖流域典型的季节性淹水湿地样带。2015年1月，将采集的土壤分装至15个盆钵中，并设置5个水分梯度以模拟该湖泊湿地的水文条件。分别于第1天、第21天、第132天采集土壤样品，开展细菌群落组成分析。
