| 摘 要： | 简述了城市降雨径流非点源污染的特征、影响因素和危害．在GIS技术支持下，估算了厦门岛内氮磷污染负荷的分布特征．在12mm雨量下，厦门岛城市径流的单位TN负荷量为44．09kg／km2，TP负荷为2．86kg／km2，氮磷污染主要来源于城市道路，其次为商住区与工业区，三者的TN、TP之和分别占全岛负荷的93．4％和92．0％．最后分析了厦门不同城市用地的降雨径流氮磷污染差别的原因，提出了减少城市径流污染的相关建议．

| Abstract: | Characteristics,influencing factors and hazards for urban rainwater runoff non-point pollution were introduced.Based on GIS,nitrogen and phosphorus load were calculated and displayed as spatial maps.With the 12 mm rainfall,total nitrogen and phosphorus load for this urban runoff of Xiamen island were 44.09 kg/km2 and 2.86 kg/km2.Urban roads are the main sources for nitrogen and phosphorus pollution.Commercial and industry areas follow.Among the three,total nitrogen load accounts for 93.4% and total phosphor... |
