摘 要:The studies were carried out on the absorption and accumulation of heavy metals in the hilly region of Southern Jiangsu *** results showed that:the forest soil in studied areas was not been polluted,owing to forest s function of accumulating heavy *** content of Zn was bigger man other 4 heavy metals in the organs of Phyllostachys *** total storage of heavy metals were ZnCuPbNi*** the enrichment coefficient of heavy metals were *** annual uptake of Cr, Cu,Ni,Pb,Zn for Phyllostachys pubescens were 29.19g/hm,278.31g/hm,89.44g/hm,87.43g/hm, 184.69g/hm respectively,annual return of Cr,Cu,Ni,Pb,Zn for Phyllostachys pubescens were 5.79g/hm, 25.84g/hm,5.12g/hm,42.06g/hm,172.56g/hm respectively,and the turnover period of Cr,Cu,Ni,Pb,Zn was 5、11、17、2、11a for Phyllostachys *** to the results of assessment,the Phyllostachys pubescens has lower enrichment coefficient,it has better ability to absorb and accumulate heavy metals in soil,owning to the bigger biomass and productivity.
