摘　　要：从水体、底泥、土壤、生物等方面分析了洞庭湖区的环境污染状况,结果表明洞庭湖水体主要受氮磷污染,底泥和周边土壤主要受重金属Cd、Cu污染。分析认为污染物排放、地质原因、外源输入和纳污能力减弱是洞庭湖区环境污染的主要原因,并提出污染治理的相关措施。The environmental pollution of Lake Dongting has been analyzed in respect of water body,sediment,soil and organism.The result shows that the lake water body is mainly polluted by nitrogen and phosphorus,while the sediment and soil are polluted by the heavy metals like Cd and Cu.It is thought that the main causes for the pollution are pollutant discharge,geological conditions,external pollution source and reduced pollutant receptive capacity.The relative pollution control measures are proposed in this paper.
