采用样地调查法，对紫金山金铜矿废弃地2003年以来进行的植被生态恢复情况进行调查，分析紫金山矿山开采前后植被恢复覆盖度和物种多样性；结合测定恢复地重金属污染情况，综合评价紫金山矿区废弃地生态恢复效果。结果表明：紫金山金铜矿矿区生态植被群落恢复中，乔木层覆盖度和物种多样性均较少；灌木层恢复较好，物种已达到12种；草本层覆盖度和物种多样性都呈上升趋势；土壤重金属污染程度明显降低，生态恢复效果较为显著。
採用樣地調查法，對紫金山金銅礦廢棄地2003年以來進行的植被生態恢複情況進行調查，分析紫金山礦山開採前後植被恢複覆蓋度和物種多樣性；結閤測定恢複地重金屬汙染情況，綜閤評價紫金山礦區廢棄地生態恢複效果。結果錶明：紫金山金銅礦礦區生態植被群落恢複中，喬木層覆蓋度和物種多樣性均較少；灌木層恢複較好，物種已達到12種；草本層覆蓋度和物種多樣性都呈上升趨勢；土壤重金屬汙染程度明顯降低，生態恢複效果較為顯著。

Survey ecology restoration of gold and copper Wasteland in Zijin Mountain since 2003,using the method of sample investi-gation,Analysis of vegetation coverage and species diversity before and after mining;combined with the determination of heavy metal pollution, comprehensive evaluation of the Zijin Mountain Mine Spoils ecological restoration effect.The results show that the purple mountain gold mine in the mining area ecological vegetation recovery,tree layer coverage and species diversity are less;the shrub lay-er recovery,species has reached 12;herb layer coverage and species diversity are on the rise,significantly decreased soil heavy metal pollution degree and the ecological restoration effect is significant.
