| 摘要: |
| 为掌握滇池流域花卉大棚种植区的非点源污染特征，提高和改善滇池水环境质量，本研究选取呈贡县斗南村花卉大棚种植区作为研究对象，在实测降雨径流数据的基础上，通过建立Storm Water Management Model模型分别对全年连续降雨条件下和典型设计降雨条件下的降雨径流水质、水量进行了模拟.研究结果表明：1）模型的流量、化学需氧量（CODCr）、悬浮物（SS）、总氮（TN）和总磷（TP）的Nash-Sutcliffe效率系数分别为0.858、0.835、0.803、0.712和0.752，能够较好地模拟研究区域的水质、水量变化.2）研究区域的平均径流系数为0.59，CODCr、SS、TN和TP的单位面积负荷率分别为118.34、82.90、54.64和5.46 kg/（hm2·a），TN和TP是主要控制的污染物.3）各污染物浓度峰值的出现时间均早于流量峰值出现的时间，因此对滇池东岸花卉大棚种植区应进行污染物尤其是TP、TN浓度与流量错峰控制. |

| Abstract: |
| In order to improve water quality of Lake Dianchi,the characteristics of non-point source pollution from flower green-house area along the east bank of the Lake Dianchi were explored.The Storm Water Management Model (SWMM) was built with measured rainfall runoff data to simulate the quantity and quality of rainfall runoff under both continuous and typical rainfall condi-tions in a flower greenhouse area in Dounan Village,Chenggong County.The results indicate that:1) The Nash-Sutcliffe efficiency coefficients of the flow,chemical oxygen demand (CODCr),suspended solids (SS),total nitrogen (TN) and total phosphorus (TP) in the SWMM are 0.858,0.835,0.803,0.712 and 0.752,respectively,so that the SWMM model can be used to predict the quantity and quality of rainfall runoff in the area.2) The average runoff coefficient of the area is 0.59.The annual loads per unit area of CODCr,SS,TN and TP are 118.34,82.90,54.64 and 5.46 kg/(ha·a),respectively.TN and TP are major pollutants.3) The peaks of every pollutant concentrations appeared earlier than the flow peak so controlling the pollutant load should be ad-vanced,especially for TN and TP controlling. |
