For evaluation of reclamation potential of Saccharum arundinaceum Retz. grown under heavy metal contaminated soils, the field investigation was conducted in Shaoguan mine areas in June 2011 with four indicators including heavy metals concentrations in soil and in S. arundinaceum, soil animal community structure, and soil pH. The sampling plots were located at Xinwenwu Village (XwV) and Jianwu Village (JwV) (respectively corresponding to the currently in production of copper ore and lead-zinc mine near), Xiatang Village (XtV) (near to tungsten mine, shutdown 25 years ago), and Tongziping Village (TzV) (with no mine pollution in the vicinity). The results show that a) pH value of sampling plots was ranked as XwV (3.84) 25.01 to 27.01 (XtV) > 7.33 (XwV) > 1.12 (TzV); c) enrichment factor of S. arundinaceum was ranked as 6.16 for XwV > 4.71 for TzV > 0.77 to 2.50 for XtV > 0.29 for JwV; d) soil animal biodiversity index for these plots was ranked as TzV > XtV > JwV > XwV, which was based on Shannon-Wiener Diversity Indices (H) and Simpson Dominance Indices (C), and TzV > XwV > JwV > XtV which was based on Pielou Uniformity Indices (E); and e) Jaccard Similarity Index (JSI) was 71.43% for plots from XwV contaminated with copper iron mine and JwV contaminated with lead-zine waste mine, and 60% for plots from XtV adjacent to tungsten mine cut-off 25 years and TzV without mine pollution in the vicinity, respectively. And these two types of plots were with different degrees of contamination. So JSI of these two types of plots varied from 25% to 30%, to be moderate degree of non-similarity. These results indicate that there was difference in the community structure of soil fauna in the S. arundinaceum community grown at different soil habitats with different degree of contamination, and diversity index was decreasing with increasing degree of pollution. These factors were the dominant factor in the decline of soil animal diversity including ISI, strong soil acidic, and continued pollution of irrigation water. At the same time, the heavy metal enrichment capacity of S. arundinaceum had little effect on the soil animal community structure diversity.%为评价斑茅对重金属污染土壤的复垦潜力,2011年6月分别对韶关矿区新温屋村和简屋村(分别对应于正在生产中的铜铁矿和铅锌矿附近)、下塘村(位于停产25年的钨矿附近)和无矿场污染的桐子坪村这4个样地的斑茅Saccharum arundinaceum进行土壤pH、土壤重金属、斑茅重金属及根系下土壤动物群落结构调查分析.研究结果如下:土壤pH从小到大的排序是:新温屋村(3.84)＜下塘村(5.74～6.07)＜桐子坪村(7.23)＜简屋村(7.24)；综合污染指数结果是:简屋村(31.54)＞下塘村(25.01～27.01)＞新温屋村(7.33)＞桐子坪村(1.12)；斑茅对Cu富集系数结果是:新温屋村(6.16)＞桐子坪村(4.71)＞下塘村(0.77～2.50)＞简屋村(0.29)；土壤动物群落多样性结果是:Shannon-Wiener多样性指数(H)和Simpson优势度指数(C):桐子坪村＞下塘村＞简屋村＞新温屋村；Pielou均匀性指数(E):桐子坪村＞新温屋村＞简屋村＞下塘村；Jaccard相似性指数结果:地处污染源附近的铜铁矿污染的新温屋村与铅锌尾矿污染的简屋村的相似数指数为71.43％,而停产钨矿的下塘村和无矿场的桐子坪村相似数指数为60％,且二类样地间两两相似性指数均达到中等程度不相似,其值在25％和30％之间.本研究表明,斑茅根系下土壤动物的群落结构及多样性受矿区污染的影响明显,多样性指数随污染程度加重而递减；土壤综合污染严重、土壤强酸性和灌溉水的持续污染是造成土壤动物多样性下降的主要因素；斑茅对重金属的富集能力的大小与其根系下土壤动物群落结构多样性关系不大.
