| 摘 要： | 按8km×8km的网格将聊城市耕地分为137个采样点，调查砷、镉、铬、铜、汞、镍、铅、锌等重金属的污染状况。采用国家土壤环境质量标准、农产品安全质量标准和绿色食品产地环境条件作为评价标准，采用单因子指数和综合指数为评价方法进行污染评价。研究表明，聊城市土壤污染强度依次为铜〉镍〉锌〉砷〉铬〉镉〉铅〉汞，但均未超标。以GIS为操作平台显示聊城市重金属空间分布状况，并对区域耕地进行了功能的定位。聊城市西南部土壤质量最优，适宜种植绿色食品；无公害蔬菜和安全粮食种植区在各县市均有不同程度的分布。

| Abstract: | As,Cd,Cr,Cu,Hg,Ni,Pb and Zn in 137 soil samples had been monitored in Liaocheng.Soil environmental quality standard,agricultural products safe standard and green food origin environmental conditions were chosen to evaluate the soil heavy metals.During the evaluation,single index and integrated index were used.The results showed that the polluted degree of heavy metals is: Cu>Ni>Zn>As>Cr>Cd>Pb>Hg.All land hasn't been polluted by heavy metals.Geography information system was used to show the distribution of d... |
