In this study, we researched quantitatively the amount of generating and flowing out non-point pollution load and we investigated the effective control method for runoff non-point pollution load with our simulation model.At first, we researched and examined the accumulated non-point pollution load in street inlets in which pollution load is flushed out from a road surface and roofs.Next, we build up a mathematical simulation model to understand mechanism of the accumulation of non-point pollution load in street inlets in urban area quantitatively.Recently, the amount of runoff pollution load has a tendency to increase and water quality become worse in receiving water area. For these problems it is effective that a controlling system for runoff storm water with storage and/or infiltration of runoff storm water covering a wide drainage area.Then we investigated the effect of this controlling system on a reduction of the amount of runoff non-point pollution load and we made clear that this controlling system has a possibility of non-point pollution load reduction.

本研究定量研究了面源污染负荷的产生量和流出量，并利用仿真模型研究了径流面源污染负荷的有效控制方法。 近期，受纳水域径流污染负荷量有增加趋势，水质恶化。针对这些问题，采用覆盖大流域的径流雨水储存和/或渗透的径流雨水控制系统是有效的。然后我们研究了该控制系统对减少径流面源污染负荷量的效果，并明确了该控制系统具有减少面源污染负荷的可能性。
