摘要
源头溪流是流域污染负荷控制的关键节点。源头溪流接纳流域内输入的污染物后,通过促进污染物在河道内的滞留及消减,降低对流域下游的输出,为下游水域水环境治理减轻压力。本文从暂储理论出发,对源头溪流营养盐滞留的研究进行了综述。介绍了暂储的定义,探讨了影响暂储区的水文、地形地貌及生物因素,分析了暂储区对溪流中营养盐滞留的作用,辨析了目前研究中存在的不足,指出未来宜在国内诸多源头溪流尽快开展相关工作,研究暂储区变化对营养盐滞留的影响机理,从而为下游流域污染负荷削减、河流廊道生态恢复提供支撑。
Headstream water is the key zone for the pollution management in a basin.The pollutants imported from the basin into the headstream water can be detained or reduced,resulting in less pollutants being transported into downstream,thus beneficing the water environmental protection in the downstream rivers.This paper reviewed the studies on the nutrient retention in headstream water based on transient storage.The concept and the types of the transient storage and transient storage zones were shown,the impacts from hydrological,geomorphic and biological factors on the transient storage zones were discussed,and the effects of the transient storage zones on the nutrient retention were also addressed.Therefore,the deficien.cies were proposed.It is urgent to undertake actions about the nutrient retention in headstream water based on transient storage in domestic rivers in future.The results will provide benefits for the pollution load reduction and the ecological restoration of the river corridor.
