摘要:
在滆湖磷的来源途径调查和磷迁移过程模型建立的基础上,计算了磷的平衡及磷浓度的变化趋势。结果表明,滆湖磷的年入湖量为270t,年出湖量为174.5t,滞留系数为0.35。在适当控制和合理利用磷资源的情况下,滆湖水体将继续维持目前的中营养水平;反之,隔湖磷浓度将逐年上升,湖水富营养化的进程将会大大加快。

Abstract:
On the basis of phosphorus source investigation and transportation modelling, the phosphorus balance ivS studied and the phosphorus concentration dynamics predicted. In Gehu Lake, the total input for phosphorus ivS 270t/a, and output 174.5t/a, with a deposit coefficient of 35%. The main input ways are inflow current, cage aquaculture and feeding. The main output ways are outflow current, harvest of fish and harvest of aquatic plants. The models of phosphorus transportation processes show that Gehu Lake will remain mesotrophic under the maintenance of macrophyte biomass. Otherwise the phosphorus concentration would be raised, and algea will become dominent to make the lake eutrophic.
Key words:  Phosphorus prediction  management  macrophyte maintenance  Gehu Lake
