摘要
通过对杨庄乡各村庄地下水水质分析,确定出水中超标物质主要为总硬度、氯化物、氨氮、铁和铅,超标率依次为83.33%、50.00%、88.89%、72.22%和55.56%。利用集对分析法对该地区地下水进行评价,在研究的20个村庄中有11个水质级别为Ⅲ级水,不适合作为饮用水,主要集中在杨庄乡东北部的沙质土区域和西部京杭运河东岸各村庄。另外,有9个村庄点位水样为Ⅰ级水和0个村庄点位水样Ⅱ级水。其评价结果将对改善该地区农村生活饮用水质量和对地下水的管理及合理利用提供指导。
The groundwater quality of Yangzhuang Township is analyzed. Results show that the main exceeding materials are identified to be total hardness,chlorlde,ammonia nitrogen,iron and lead. There over limit rates are 83.33% ,50. 00% ,88.89% ,72.22% and 55.56% respectively. The groundwater of this region is evaluated by Set Pair Analysis Method, showing that among 20 villages, water in 11 belongs to grade Ⅲ, which is not fit for drinking and mainly concentrated in sandy soil region in the northeast of Yangzhuang Township and villages on the east coast of Beijing-Hangzhou Grand Canal in the western. Water in the other 9 belongs to grade Ⅰ and without grade Ⅱ. With the evaluate results, the scientific basis is provided for improving the quality of rural life drinking water and groundwater management.
