| 摘 要： | 为了解于桥水库菹草腐烂分解后对水体理化指标和氮磷释放规律,在室内进行为期57 d的菹草腐烂分解试验。通过水质监测和取样化验,结果表明：菹草腐烂分解不伴随放热反应;分解分为前期的快速分解和后期的稳定释放2个过程;菹草体内磷的释放过程缓慢;在水体中氮磷不被转移的情况下,40 d左右菹草腐烂分解释放到水体中的氮磷达到峰值。

| Abstract: | In order to understand physical and chemical indicators of water bodies after Potamogeton crispus decomposing and phosphorus release pattern in the Yuqiao Reservoir,a interior test of Potamogeton crispus decomposing in water with the period of 57 days was carried out.Through water quality monitoring and sampling detection,it＇s concluded that decomposition of Potamogeton crisp us wasn＇t accompanied by an exothermic reaction.The decomposing process was constituted by two processes as early rapidly decomposition and later stably release.The release process of phosphorus was slow in Potamogeton crispus ,and the release peak arrived at about 40 days when nitrogen and phosphorus released into the water without transfer. |
