泾、浜发展与吴淞江流域的圩田水利(9-15世纪)

The development of Jin-Bang and the Wei-field irrigation in Wusong river valley 9th-15th century

自宋代的塘浦系统开始瓦解以来,吴淞江流域的泾浜体系开始发展。泾浜水系和以后溇的出现,基本上人为形成的。在不断的历史发展中,泾浜体系形成具有干枝结构的网状水系,这种结构非常稳定地存在了近500年。这种结构下的圩田水利模式一般是小圩模式。在冈身感潮地区,泾浜体系比较密集,且末端水系有弯曲化现象;在低地地区,为了排水的方便,河道的干枝体系较为顺直。在这种体系下,治水必须与治田相结合。到后期,随着圩田治理的深化,进一步出现了称为溇的末端水系。

After the Tang-Pu systems had been collapsed since Song dynasty, the Jin-Bang system began to develop. Jin-Bang system and the river terminus called Lou, were totally developed by human action. In the process of the developing, Jin-Bang systems formed branches and trunk structure in hydrographic net system. The structure had gotten a very stable acting mode in 500 years. Wei-field irrigation in this river structure was small Wei-field pattern. In ridge area where rivers affected by tide, Jin-Bang system is more concentrated, and the terminus of river system were curved; in lower ground, branches and trunk of river was more straight for draining off water. In this system, water control must united with field managing. In the later period, as the development of field managing, a terminus of river system be call as Lou is emerged.
