摘　　要：为全面了解黑龙江省东部矿区废弃地重金属含量及其潜在生态危害程度,选取5种处于自然状态的典型废弃地及对照地,共采集了125个样品,测试了Pb、Zn、Ni、Cr、As、Hg等共6种重金属元素。分析和评价结果表明:黑龙江省东部矿区废弃地受多种重金属污染,各种重金属的污染程度由强至弱依次为:Hg>Cr>Ni>Zn>Pb>As;5种典型废弃地的综合污染指数由低到高排序为:矸石山<排矸场<粉煤灰堆场<石墨尾矿坝<水泥采矿坑;重金属污染物对黑龙江省东部矿区构成的潜在生态危害由强至弱依次为:Cr>Ni>Pb>Hg>Zn>As,黑龙江省东部矿区5种类型的矿区废弃地潜在生态危害普遍达到严重程度以上,其潜在危害程度由低到高的排序依次为:矸石山<排矸场<粉煤灰堆场<水泥采矿坑<石墨尾矿坝。In order to find out tlie heavy metal concentrations and their potential ecological and mining wasteland in eastern mining area of Heilongjiang Province’this program selected 125 samples from five types of typical industrial wasteland in natural state and their contrast land for analyzing Pb Hg.The results indicate that the industrial and mining wastelands in eastern mining area of Heilongjiang have been contaminated by many heavy metals.The descending order of pollution degree of various heavy metals is Hg>Cr Ni>Zn>Pb>As.The ascending order of pollution degree of industrial and mining wasteland is gangue discharged dump<gangue stacking yard<coal asli stacking yard<graphite tailings dam<cement mine open-pit.The potential ecological risk intensity caused by different heavy metals is Cr>Ni>Pb>Hg>Zn>As.The potential ecological risks generally reach more than severity of the industrial and mining wasteland in eastern mining area of Heilongjiang Province.The ascending order of the potential ecological risk index is gangue discharged dump<gangue stacking yard<coal asii stacking yard<cement mine open-pit
