| 摘 要： | 应用混合加权模式对天津城郊农田土壤的重金属污染进行评价,并与内梅罗指数法计算的综合污染指数进行对比,以GIS输出表达,认为混合加权法对环境质量具有较好的灵敏性,能将环境质量的差别较好的区分开来。根据混合加权的计算结果,利用地统计方法,在GIS的支持下,得出天津城郊混合加权的分析结果。

| Abstract: | Assessment of pollution of heavy metals in soils of Tianjin suburb land was done by a mixed weighted model and the results were compared with Nemerow index.Both analysis results were displayed on GIS in the present investigation.It could be concluded that the mixed weighted model was characterized by a better sensitive to express environmental quality and its computing answer was capable of distinguishing the studied area environmental quality at high reality.Using geostatistical techniques,the analysis results of the mixed weighted model based on GIS was also concluded in our study. |
