东苕溪是太湖上游三大河流之一(另为西苕溪及荆溪),它不同于其他河流以自然形成为主,则是历代先民为兴利除害在自然水系的基础上因地制宜地不断改造而成,由此改善了流域低洼区的水环境,为之渐次开发提供了有效保障。作者解读了东苕溪名的由来及时空上的具体所指,并就其中一支余不溪之名作了新的考释;在此基础上进一步探究了东苕溪的形成和变迁,尤其是湖州境内下游的来龙去脉;揭示了它的形成过程就是先民合理利用和改造自然、有效发展该流域社会经济的过程,可谓是环境变迁与经济发展积极互动的典范。而今,它的兴废不仅关乎杭州与湖州地区的经济发展和生存环境,对整个太湖流域的经济发展和环境治理亦是至关重要的。
Dongjuxi is one of the three major rivers in the upper reaches of Taihu Lake (the other is Xitiaoxi and Jingxi), which is different from other rivers to form the main natural, it is the ancestors of successive generations in order to change the natural water system, based on the continuous transformation of natural conditions Thus, it improves the water environment in the low-lying areas of the basin, which provides an effective guarantee for the gradual development. The author interprets the origin of Dongbaoxi and its concrete meaning in time and space, and makes a new examination on the name of one of the remaining streams. On this basis, it further explores the formation and change of Dongbaoxi, especially in the downstream of Huzhou It reveals that the process of its formation is that the ancients rational use and transformation of nature and effectively develop the social economy of the basin can be described as an example of positive interaction between environmental change and economic development. Nowadays, its rejuvenation is not only related to the economic development and living environment in Hangzhou and Huzhou, but also vital to the economic development and environmental governance of the entire Taihu Lake Basin.
