| 摘 要： | 对乐安江水系的底栖动物及其生活环境进行的研究表明，位于乐安江上游的德兴铜矿排出的大量酸性废水对主活在该水系中的底栖动物的分布及其群落结构会产生直接影响．废水中的各种污染物质，尤以重金属（特别是铜和铅、锌、镉）对底栖动物群落的抑制作用最大．在下游，随着同污染源距离的增加，河流的污染状况逐渐减轻，底栖动物种类多样性逐渐增加，清洁种类逐渐恢复．另外，河流水量的季节性变化对河流自身的净化作用会产生很大影响．

| Abstract: | The result from the steady on the biological effects of Dexing copper mine drainage on the Lean River,Jiangxi Province confirmed that the metal pollutants(especially Cu,Pb,Zn and Cd)produced a direct effect on the distribution and community structure of benthic macroinvertebrates.In the seriously polluted areas,almost all the orsanisms were extinct. In the lower reaches,the benthic comnunity gradually restored. Due to the seasonal changes of water flow coming from the upper reaches,the purifitution capability of the river itself was fluctuated sisnilicantly. |
