| 摘 要： | 黑龙江多宝山铜成矿区属于大兴安岭森林沼泽景观区,在该区进行植物地球化学找矿具有一定优势。在植物地球化学找矿中,有效指示元素和有效指示植物是主要评价指标。本文研究目的是如何确定有效指示元素和有效指示植物。通过多宝山铜成矿区和相邻对照区植物地球化学对比研究,提出有效指示元素和有效指示植物选择的原则和方法。提出利用衬度系数(KCD)、组合衬度系数(ZKCD)、屏障系数(KPZ)等多指标方法选择有效指示植物。研究认为,多宝山成矿区有效指示元素为Cu及Ag、Mo、Co、Pb、Zn、W,白桦和胡枝子可作为有效指示植物。

| Abstract: | Abstract: The Duobaoshan copper ore district is located in the Da Hing An Ling forests marsh landscape area. There are some advantages for phytogeochemical prospecting in this area. Effective indicating elements and effective indicator plants are essential evaluation indicators in phytogeochemistry prospecting. The purpose of this paper is to define the effective indicator elements and effective indicator plants. Based on the studies of phytogeochemistry in the Duobaoshan copper ore district and comparison with neighboring areas, the principle and selection method for effective indicating elements and plants were proposed. The contrast coefficient (KCD), combination contrast coefficient (ZKCD) and shielding coefficient (KPZ) were put forward for selecting effective indicating plants. The elements Cu, Mo, Co, Pb and Ag, and the plants platyphylla and lespedeza can be regarded as effective indicators in the Duobaoshan copper metallogenic field. |
