河台金矿位于中国广东西部山区，属南亚热带气候区，该区次生针阔叶混交林发育，覆盖率大于７０％。矿区植物受Ａｕ及伴生元素严重毒化，研究结果表明，河台金矿区植物叶中的Ａｕ含量比对照区高３０多倍，Ａｇ、Ｃｕ、Ｐｂ、Ｚｎ、Ｈｇ的含量均与对照区处于同一数量级；河台金矿植叶色素中的Ａｕ、Ｃｕ是对照区的２倍多，Ａｇ、Ｈｇ、Ｓ、Ｍｎ的含量均与对照区的处于同一数量级，但显弱正异常，Ｚｎ、Ａｓ、Ｓｂ、Ｍｇ也与对照区的处于同一数量级，但显弱负异常；金矿区植物叶中叶绿素和类胡萝卜素的含量均比对照区的高，叶中水含量和叶面温度则比对照区的低；金矿区的叶体细胞发生一系列变异。以上结果可作为植被地区找隐伏金矿的生物地球化学标志。
Hetai Gold Mine is located in the western mountainous area of Guangdong, China. It belongs to the southern subtropical climate zone. The secondary coniferous and broad-leaved mixed forest develops in this area with a coverage rate of more than 70%. The results showed that the content of Au in plant leaves in Hetai gold mining area was more than 30 times higher than that in control area, and the contents of Ag, Cu, Pb, Zn and Hg were all the same in control area The content of Ag, Hg, S, Mn in the pigment of the Hetai gold mine was twice as much as that of the control. The content of Ag, Hg, S and Mn were in the same order of magnitude as that of the control area, Sb and Mg were also in the same order of magnitude as those in the control area but significantly weaker than those in the control area. The content of chlorophyll and carotenoid in the leaves of the gold mining area was higher than that of the control area. The leaf water content and leaf surface temperature were higher than those in the control area Of the low; gold mine area leaf cells occur a series of variation. The above results can be used as biogeochemical markers to find hidden gold deposits in the vegetation area.
