摘　　要：土壤重金属的污染会对生态系统产生严重的危害,已经引起广泛关注。矿山开采、金属冶炼、燃煤、工业废水等是重金属人为污染源。为了评价兖矿地区的重金属分布的状况,采用网格布点法,对兖矿地区的农田进行采样并分析,对土壤中的铅、镉、锌和镍等六种重金属含量进行检测,获得了大量数据。基于内梅罗污染指数提出了加权土壤污染评价指数,并用GIS展绘成图。结果表明,一部分地区表土中重金属含量较高,镍、镉等重金属有可能对该地区农业生产构成威胁,应当引起足够的重视。The soil pollution caused by some heavy metals can be harmful to the ecological system seriously and has led to the people＇s extensive concerns. In order to assess the heavy metal pollution of the farmland of Yanzhou mining area, 144 top soil samples were collected and 36 compounded samples were made from them. Six heavy metals, including lead, cadmium, chromium, copper, zinc and the content of nickel were analyzed using atomic absorbent spectrometry analyzer （AAS）. Then modified synthetic pollution index for soil was given in the paper. Assessment result shows that a part of Yanzhou mining area has been polluted by the heavy metals. Measures should be taken to deal with it as soon as possible.
