摘要本研究的目的是分析三个商业用地的径流和污染物输出特征：一个没有雨水控制措施（NoTreat），一个有湿滞留盆地（WetBasin），一个有低影响开发（LID）措施。这些地点位于北卡罗莱纳州中部的皮埃蒙特和海岸平原地理区域。使用自动雨量计和采样器对每个站点的降雨量、径流和污染物浓度进行了一年多的监测。径流中总凯氏定氮（TKN）、硝态氮+亚硝酸盐氮（NOx-N）和总磷（TP）的风暴事件平均浓度（EMCs）普遍低于美国其他许多城市地区的相应EMCs。此外，EMCs与北卡罗来纳州八个停车场的EMCs相似。NoTreat站点的暴雨径流与降雨量之比最大，而WetBasin站点的最小，这是可以预料到的，因为NoTreat站点没有滞留/储存，而WetBasin位于…
AbstractThe purpose of this project was to characterize runoff and pollutant export from three commercial sites: one with no storm water control measures (NoTreat), one with a wet detention basin (WetBasin), and one with low impact development (LID) measures. The sites were located in the Piedmont and Coastal Plain physiographic regions of central North Carolina. Rainfall, runoff, and pollutant concentrations were monitored at each site for more than one year by using automated rain gauges and samplers. The storm event mean concentrations (EMCs) of total kjeldahl nitrogen (TKN), nitrate+nitrite nitrogen (NOx-N), and total phosphorus (TP) in runoff were generally less than corresponding EMCs for many other urban areas in the United States. Also, EMCs were similar to those found for eight parking lots in North Carolina. Storm runoff to rainfall ratio was greatest for the NoTreat site and least for the WetBasin site, which was anticipated because the NoTreat site had no detention/storage and the WetBasin sit...
