[Research progress on phosphorus budgets and regulations in reservoirs].

Phosphorus is an important limiting factor of water eutrophication. A clear understanding of its budget and regulated method is fundamental for reservoir ecological health. In order to pro- mote systematic research further and improve phosphorus regulation system, the budget balance of reservoir phosphorus and its influencing factors were concluded, as well as conventional regulation and control measures.

[Responses of riverine nitrogen export to net anthropogenic nitrogen inputs: a review].
