摘要：2007年，污染物总量管理系统（TPLMS）第一次用于韩国高度发达的马山湾流域。为了评估污染物总量管理系统对水质的改善效果，本文分析了2005年到2010年间河流和海湾中化学需氧量（COD）、悬浮物（SS）、总氮（TN）和总磷（TP）的变化情况。在此期间，陆源污染物总量都有所下降，尤其是化学需氧量和悬浮物总量有显著降低（ρ < 0.01）。同时，海水中的化学需氧量也有明显下降（ρ < 0.01）。从化学需氧量和叶绿素a反应的滞后性可以估算出海水的停留时间为一个月。海水中陆源营养物质总氮（ρ < 0.01）和总磷（ρ < 0.05）也有显著减少，但是海湾中确没有明显降低，这说明有其他的非点源营养物进入到海湾中。

Abstract: The total pollution load management system (TPLMS) was first applied in 2007 to the highly developed Masan Bay watershed, Korea. To evaluate the effect of TPLMS on water quality improvement, we analyzed the water qualities in rivers and bay during 2005–2010, targeting chemical oxygen demand (COD), suspended sediment (SS), total nitrogen (TN), and total phosphorus (TP) loads. Land-based pollutant loading all decreased during this period, with a significant reduction in COD and SS loads (ρ < 0.01). The COD reduction in seawater, following the TPLMS implementation, was also significant (ρ< 0.01). Time-lagged responses in COD and Chl-a supported an estimated seawater residence time of ∼1 month. Land-based nutrient loads were also significantly reduced for TN (ρ< 0.01) and TP (ρ< 0.05), however, significant reductions were not observed in the bay, indicating potential alternative nutrient inputs from non-point sources into the bay system.
