长江白鹤梁72个历代枯水位水文统计表测算纪实

Record of hydrological statistics of 72 dry water levels calculation in White Crane Ridge Inscription in Changjiang River

长江重庆市涪陵白鹤梁石鱼题刻,是享誉世界的一座“古代水文站”。白鹤梁的72个历代枯水位高程数据,在1972年就已测定推算完成,是白鹤梁唯一的一份72个枯水位水文统计表,一直没有对外公开发表其具体内容。现今在社会各界的研究文章和宣传展览中,虽有谈及白鹤梁的72个水文年份之事,但都不知道这72个水文年代的详细数据和内容,甚至还有多处错误。为了社会各界学者们能正确完整地使用白鹤梁的72个历代枯水水文年份统计数据,现将调查组当年参与调查和测算白鹤梁72个水文年份的工作过程纪实进行说明,包括新、旧两代石鱼水标的辨识与确定以及石鱼水标高程测定与72个水文题刻的推算,并首次将1972年“长江流域规划办公室和重庆市博物馆枯水调查组”推算的白鹤梁72个历代枯水位高程统计表全部数据公布。

The White Crane Inscription of stone fishes(Baiheliang Inscription)in Fuling District,Chongqing City,is a world-famous"ancient hydrological station"of the Changjiang River.The 72 ancient dry water levels data incised on White Crane Inscription was determined and calculated in 1972,forming the only hydrological statistics table of 72 dry water level about the inscription,however its specific contents have not been publicly published.Nowadays,in the research articles and publicity exhibitions from all walks of society,although there are talk about the 72 dry water level hydrological years of Baiheliang,they don t know the detailed data and content of these 72 hydrological years,and there are even many mistakes.For correctly and completely using the statistics of the 72 dry hydrological years in Baiheliang,the work process of investigating and measuring the 72 hydrological years of Baiheliang in the previous exploration was explained in this paper,including the identification and determination of new and old generations stone fish-like water gauge,the elevation measurement of stone fish water gauge and the calculation of the 72 hydrological inscriptions.For the first time,all the data of the 72 dry water level statistical tables of Baiheliang Inscription are released,which were calculated by the Changjiang River Basin Planning Office and the Chongqing Museum Dry Water Investigation Team in 1972.
