模糊综合评价法在土壤环境质量评价中的应用实例

Application of fuzzy comprehensive assessment in soil environmental quality evaluation

采用模糊综合评价法对土壤环境质量进行评价,可有效地克服土壤环境污染状况的渐变性和模糊性。通过对阜新污灌区5个不同地块土壤环境质量进行模糊综合评价实例验证结果表明:该评价方法可以科学、有效地应用监测数据,评价结果较为可信,能较科学地判定土壤环境质量级别,同时也可反映各污染因子对土壤环境质量的影响程度,并对污染程度加以区分和量化。该方法可为土壤环境规划及污染防治提供依据。

The soil environmental quality was evaluated by fuzzy comprehensive assessment method, which could decrease the gradual change and fuzz of soil environmental pollution. The soil environmental quality at five plots of sewage irrigation region in Fuxin was validated by fuzzy comprehensive assessment method. The results indicate that this assessment method is feasible. And the method can also detect the soil environmental grades scientifical- ly. The effects of different pollution factors on soil environmental quality can be estimated, and the pollution grades can be divided and evaluated. The method can provide the base for soil environmental plan and pollution prevention and cure.
