【摘要】 中国正在建设各种大、中型水电站,各种大、中型水库数量也相应增加。水流进入库区后,流速将减缓,因此,库区水体更容易出现富营养化问题,而氮、磷是影响水体富营养化发生的主要因素,为保护库区生态环境,有必要将库区底泥对氮磷的吸收规律进行研究,以便对库区水体中的总氮和总磷进行控制,从而防止库区水体发生富营养化。文章采用实验方法将白鹤滩库区底泥对水体中总氮和总磷的吸收进行了研究,得到了底泥中总氮和总磷的吸收规律,为进一步进行白鹤滩库区富营养化研究提供了基础数据。更多还原

【Abstract】 China is now constructing every kind of hydropower station and the amount of reservoir increases accordingly.After water flow entering reservoir area,the velocity of flow will decrease,and therefore the ecological problem will emerge out more frequently.Nitrogen and phosphorus is the main cause for water ultra-nutrition.In order to protect the ecological environment,it is necessary to research the law of total nitrogen and phosphorus absorption in sediments so as to control it.As a result,prevent water Eutrophication.The absorption of total nitrogen and phosphorus from sediments in Baihetan is studied in this paper.We gained the law of total nitrogen and phosphorus absorption in sediments.All these work could offer the basic database for the further study of water ultra-nutrition.更多还原
