| 摘 要： | 选择京承高速公路沿线蔬菜地、粮田及果园3块典型的农产品产地作为研究对象,采用地积累指数法和生态危害指数法分别对其重金属污染状况进行评价.地积累指数法评价结果表明:蔬菜地中突出污染元素为Zn,地积累指数为0.17,达到轻度～中等污染水平；粮田中主要污染元素为Cu,地积累指数为0.6,同样为轻度～中等污染水平；果园中突出污...

| Abstract: | To evaluate the heavy metal pollution of farmland in Beijing suburbs,the vegetable farm,grain field and orchard along the Jingcheng Expressway were investigated in terms of the index of geo-accumulation(I_(geo))and the potential ecological risk index(RI).The I_(geo) evaluation result indicated that Zn was the most serious pollution element on the vegetable farm,the I_(geo) was 0.17,and the vegetable farm was at a low or medium pollution level;Cu was a main pollution element in the grain field,the I_(geo) wa... |
