| 摘 要： | 基于ArcGIS软件,依据土地利用、土壤类型等遥感数据生成聊城市东昌府城区的土地利用图,统计不同土地利用类型的面积,将研究区域按不同功能分为居住区、交通区、工业区、绿化用地、公共建设用地和未利用土地,选择不同CN(Curve Number)值,采用SCS径流曲线模型计算2009年的径流深度和年径流量。结果表明:聊城市东昌府区2009年不同功能分区的降水径流深度分别为272.47 mm、465.00 mm、277.16 mm、30.68 mm、128.47 mm、167.51 mm,同时,根据研究区域内悬浮物(SS)、化学需氧量(COD)、总氮(TN)、总磷(TP)等污染物的平均浓度,估算得出它们的负荷量分别为8 558.8 t、2 415.32 t、201.29 t、10.08 t。 |

| Abstract: | Based on ArcGIS software as well as remote sensing data of land use and soil classification,the land use map of urban area of Dongchangfu,Liaocheng was generated for the statistics of different land uses.The study area was divided as residential area,traffic area,industrial zone,green land,public construction land and unused land.2009 runoff depth and annual volume of runoff was estimated using SCS runoff curve model by different curve number(CN) values.Results showed that 2009 rainfall runoff depth of different functional divisions in Dongchangfu District,Liaocheng were 272.47 mm,465.00 mm,277.16 mm,30.68 mm,128.47 mm and 167.51 mm respectively.Based on average concentration of different pollutants,the pollutants loads of SS,COD,TN,TP were calculated as 8,558.8 t,2,415.32 t,201.29 t and 10.08 t respectively. |
| Keywords: | urban surface runoff SCS model volume of runoff pollution loads |
