三峡工程库区文物保护实施阶段的序幕,是从三峡工程实现大江截流的1997年拉开的。三峡工程实行分期蓄水,从1997年大江截流到2003年6月,属于二期阶段。配合三峡工程的库区文物保护工作也相应按照水位高低的原则,制定出阶段性目标,这就是:2003年6月前,重庆库区在地下文物方面涉及310项,要完成的发掘总面积为57.0965万平方米,勘探总面积为677.2808万平方米。如果把发掘面积换算为约2米宽度的探沟,它可以在从巫山到涪陵的二期水位范围内,遍布长江两岸,勘探面积则以20余米的宽度遍布长江两岸。
The prelude to the implementation stage of cultural relics protection in the reservoir area of the Three Gorges Project was opened from 1997 when the Three Gorges Dam was closed. Three Gorges Project implementation of staging water, from the river closure in 1997 to June 2003, belong to the second phase. In line with the Three Gorges reservoir area cultural relics protection work is also in accordance with the principle of high and low water levels to develop a phased goal, which is: Before June 2003, Chongqing reservoir area involving 310 underground cultural relics, to be completed to explore the total area of 57.0965 million square meters, the total exploration area of 6,772,800 square meters. If the excavation area is converted into a trench of about 2 meters in width, it can be found across the Yangtze River in the second stage of water level from Wushan to Fuling. The exploration area covers a total area of more than 20 meters across the Yangtze River.
