冰期输水安全问题是目前北方缺水地区引水,调水一个值得研究的重要问题。1981年冬季引黄济津过程中,南运河沧州地段发生了较为严重的流冰、壅冰现象,严重地影响了輸水安全。为了摸清该地区的冰情规律,确保今后冰期输水的安全,我们观测并调查了这次冰情发生、发展的过程,并结合1953年～1974年南运河捷地站有关冰情、水温、气温等观测资料
The issue of water transport safety in glaciation is an important issue that is worth studying for water diversion and water diversion in the northern water-scarce regions at present. In the winter of 1981, during the process of diverting the Yellow River and the Yellow River, severe ice-flow and ice-icing occurred in the Cangzhou section of the South Canal, which seriously affected the water transport safety. In order to find out the law of ice conditions in the region and ensure the safety of water transport in the future ice age, we observed and investigated the occurrence and development of the ice conditions. In connection with the ice conditions and water temperature at the South Grand Canal Station from 1953 to 1974, , Temperature and other observation data
