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。
以東江湖流域為研究對象,對其水汙染及其分佈情況進行瞭識彆以及對三次產業結構特彆是對農業產業結構的縯變進行描述併測算瞭Hamming貼閤度;運用典型相關分析方法研究瞭湖泊流域水環境對產業結構及農業產業結構的響應規律。研究錶明:東江湖流域近10年產業結構貼閤度較低,不閤理程度上升,第一產業農業比重過高,由此產生的農業麵源汙染是流域水環境質量下降(化學需氧量COD、總燐TP、總氮TN)的主要原因。農業結構中漁業與COD排放高度正相關,畜牧業及農業種植與COD、TP和TN呈中度正相關。因此東江湖流域產業結構優化的方嚮是降低第一產業產值比例,提高第三產業產值比例,鼓勵髮展生態農業及生態旅遊業,同時積極優化農業產業內部結構,積極髮展生態友好型農業產業。

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.
