论唐代引泾灌渠的渠系变化与效益增加

Discuss about the Irrigation System Changes on the Jing River in Tang Dynasty and the Increased Benefits

唐代引泾灌溉系统发生重大变化,原来以郑白二渠作为灌区的南北两条干渠,经过多次改建,郑国渠的渠首段到唐代中期逐渐失去效用,其下游的冶、清、浊、漆、沮诸水各自形成了独立发展的灌渠系统。唐后期的引泾灌溉系统以白渠为主,逐步发展成南北中三条干渠,设三限闸、彭城堰,分水设施健全,干支斗渠配套,灌溉体系趋向完善,管理技术空前先进,发挥出了巨大的经济效益。

The irrigation system on the Jing river changed a lot during Tang dynasty. The Zheng Guo channel and Bai channel used to be the arterials from north to the south in the area. After several times rebuilt, the head part of Zheng Guo channel gradually lost its efficiency in the mid-Tang dynasty .Its downstream ,such as Ye fiver, Qing river ,Zhuo river, Qi river, Ju river all formed their own independent irrigation system .The Jing river＇s diversion system mainly by the Bai channel, gradually developed into three trunk from the south via middle to the north, those are, the three gateway, Peng Cheng weir, and the tapping facility worked sound, the trunk and the branch matched well, and the irrigation system tends to be perfect, managerial technique advanced unprecedented .What we mentioned above had bring into play huge economic efficiency in that time.
