摘要
以上海朱家角镇为研究对象,结合遥感影像数据分析、历史资料收集整理、实地调查访谈,探讨基于河网水系的江南水乡风貌和文化保护途径,结果显示:①2006年朱家角共有河道374条,其中88.7%为村级河道;镇内水环境质量不容乐观,除溶解氧及化学需氧量外其余监测指标均未达到Ⅱ类地表水标准;②1965~2006年朱家角河网水系结构趋于主干化和简单化,期间消失河流164条,消失河流总长达27.77km,消失河流面积共0.45km^2,消失河流均为村级河流;近40年,水乡文化在桥梁、街巷、民居、宗教性建筑及地名等要素上产生了相应变化;③从末端河道重视程度、城镇水环境整治、水乡文脉保育等方面提出建议,以便开展基于河网水系的江南水乡文化保护工作。
In this paper,Zhujiajiao of Shanghai was taken as a case to study the protection of Jiangnan water-town culture,by processing and analyzing re mote sensed images and historical data. The results show that: (1)there are 374 rivers in Zhujiajiao 2006,and 88.7% of them are village-scale rivers. All the items cannot meet the standard for surface water of class Ⅱ,expect dissolved oxygen(D0)and chemical oxygen demand(COD);(2)the structure of river system has becoming oversimplification between 1965 to 2006. Over 164 rivers,with a length about 27.77km and area about 0.45km2 disappeared,and all of them are village-scale rivers. Some cultural elements have changed over the past 40 years;(3)some suggestions were put forward on the attention degree of low class rivers,water environment improvement and conservation of specific culture,to protect the Jiangnan water-town.
