基于可拓学的护城河水环境质量评价

针对护城河的水环境质量问题,以CODMn、氨氮、TN、TP、NO3-N为评价指标,采用可拓学物元分析方法,研究了荆州护城河的水环境质量状况。结果表明,与水质单指标评价比较,得出影响荆州护城河水质类别的主要因子为:TN、CODMn、氨氮、TP和NO3-N。对溶解氧的参数做了敏感性分析,表明溶解氧参数在本例中不敏感。

Aiming at the problem of water environment quality in Jingzhou Moat, taking CODMn, NH3-N, TN, TP and NO3-N asevaluation indexes and adopting the method of extension matter-element analysis, the water environment quality status of JingzhouMoat was studied. The results show that the main factors affecting the water quality of Jingzhou Moat are院 TN, CODMn, NH3-N, TPand NO3-N, compared with the evaluation of single index of water quality. The sensitivity analysis of the dissolved oxygen parametersshows that the dissolved oxygen parameters are insensitive in this case.
