摘　　要：应用生物地球化学方法对北山地区公婆泉铜矿区进行了区域植物地球化学试验研究 ,表明一些荒漠植物对生存环境中某些元素的富集具有很好的示矿性 ,尤其是该区植物中和第四系沟谷粗碎屑中的铜具有非常强烈的相关性 ,它们在区域含量分布上也有一定的相似性。部分区域的植物和粗碎屑的锌、银、铅含量具可比性。本区植物测量的铜、锌、银和铅具找矿意义 ,钼、砷、钴对铜矿示踪没有特殊的地质意义。Using the biogeochemical method, the authors made regional botanogeochemical experimental researches in the Gongpoquan copper ore district of Beishan area. It is shown that some desert plants have good ore-indicating significance to some elements in their living environments, that the plants of that area demonstrate especially strong correlation with copper in Quaternary coarse fragments within ravines and valleys, and that their regional distribution also assumes some similarity. In some districts, plants are comparable with coarse fragments in contents of such elements as Zn, As and Co. It is also concluded that in vegetation survey of this area, Cu, Zn, Ag and Pb have ore-prospecting indicator significance, whereas Mo, As and Co have no special tracing significance for copper deposits.
