摘　　要：界牌河段航道整治工程于 1994年动工 ,1998年基本结束。为了防止在施工过程中对白豚和长江江豚造成意外伤害 ,并对整治该河段的环境变化对白豚和长江江豚的影响作出评价 ,作者在 1995年至 1999年在界牌河段对白豚和江豚的活动和航道整治前后的情况进行了监测。调查结果表明 ,界牌航道在整治过程中没有对白豚和江豚造成伤害 ,原来碍航严重的界牌航道得到了有效的整治 ,同时也有利于白豚和江豚的活动。The Navigation Channel Renovation Project in Jiepai Section of the Yangtze River was carried out from 1994 to 1998.For preventing incidental hurt to baiji (Lipotes vexillifer) and Yangtze finless porpoise \%(Neophocaena phocaenoides asiaeorientalis) \%by the project,activities and movements of these animals had been monitored in the period,and the environment situation was evaluated and compared before and after the project.Studies showed that there was no incidental hurt or injury for baiji and the porpoise during the period.The old navigation channel had been much improved after the project,which benefits baiji and the porpoise inhabited there.
