摘要
对于海量的区域土壤地球化学数据,快速准确的处理与分析评价是其迫切要求。本文根据土壤环境质量标准,结合层次分析法对因子权重进行确定,并采用加权平均型综合指数法进行污染程度分析,结合GIS空间分析技术,对萧山区进行较为系统的环境地球化学质量评价,并重点对该区的重金属元素污染进行了评价。结果表明,萧山区有不同程度的砷、汞、镉、锌、铜和铅重金属污染,尤其以城镇及其城郊尤为严重。
Quick and correct disposal and analysis of the spatial data of regional geochemical is urgently needed. And in the filed of regional geochemical quality evaluation, introduce the GIS technology may be introduced to evaluate quality of geochemical and select geochemical tiny element which can influenced agriculture, stockbreeding and fishing for mapping and evaluation. Then geochemical quality was analyzed and evaluated through displaying the maps by grade and layers, using advanced computer method and evaluating thinking in order to instruct the adjusting of the structure of the agriculture, stockbreeding, fishing and optimizing the environment.
