| 摘 要： | 运用SWAT模型对晋江西溪流域的非点源污染进行了研究．在产流、产沙模拟的基础上，利用1973—1979年晋江西溪安溪站的氨氮、矿物磷实测值对模型进行校准，氨氮、矿物磷模拟的效率系数分别为0．69和0．79．模拟结果表明，1973-1979年西溪流域年均坡面非点源总氮流失量约为1530t或6．3kg／hm^2；总磷流失量约为270t或1．1kg／hm^2；耕作农田是非点源污染的重要来源；非点源污染在西溪各子流域中的空间分布不平衡，蓝溪子流域部分污染较严重．

| Abstract: | The SWAT model was applied to stimulating the transport of nitrogen and phosphorous in Xixi watershed within the Jinjiang River Basin.Calibrated by comparing the observed ammonia-nitrogen and mineral phosphorous with the simulated results,it was found that the Ens of ammonia-nitrogen and mineral phosphorous reached 0.69 and 0.79 with the minimum relative error 5.3% and 1.4%,respectively.The simulated results also showed that the annual TN pollution from non-point source was 1 530 t,or 6.3 kg/hm2 and the ann... |
