以东江湖流域为研究对象，对其水污染及其分布情况进行了识别以及对三次产业结构特别是对农业产业结构的演变进行描述并测算了Hamming贴合度；运用典型相关分析方法研究了湖泊流域水环境对产业结构及农业产业结构的响应规律。研究表明：东江湖流域近10年产业结构贴合度较低，不合理程度上升，第一产业农业比重过高，由此产生的农业面源污染是流域水环境质量下降（化学需氧量COD、总磷TP、总氮TN）的主要原因。农业结构中渔业与COD排放高度正相关，畜牧业及农业种植与COD、TP和TN呈中度正相关。因此东江湖流域产业结构优化的方向是降低第一产业产值比例，提高第三产业产值比例，鼓励发展生态农业及生态旅游业，同时积极优化农业产业内部结构，积极发展生态友好型农业产业。

A case study on water environmental deterioration from change of industry structure in Dongjiang lake basin was conducted.Firstly the kind of water pollution and its distribution were identified,then the evolution of industry structure especially agriculture structure in the last ten years and its Hamming ap-proach degree were studied,and the corresponding response of water environment of the lake basin was ana-lyzed with canonical correlation analysis.The results show that the Dongjiang Lake industry structure evolved unreasonably with the decreasing of its Hamming approach degree and with the increasing proportion of agricul-ture.So the pollutants from agricultural structure caused water deterioration including chemical oxygen demand (COD),total phosphorus(TP) and total nitrogen(TN).And in agriculture structure fishery was highly positive correlated with the COD emission,while farming and animal husbandry were moderately positive correlated with the COD,TP and TN emission.The conclusion can be drawn that the ratio of first industry i.e.agriculture struc-ture should be decreased so as to optimize the industry structure of Dongjiang Lake basin,and that of the third industry,such as ecological tourism,should be incteased.In addition the internal structure of agriculture should be optimized,and ecological farming be developed.
