我省北部引嫩从1976年江道枢纽工程建成至今,引水口江段一直处于发展演变之中,1987～1989年,1993年两次大的整修工程虽对保障引水起到了作用,但大江一直处于向不利于引水方向演变,引渠引水能力逐年降低.为了扭转这种不利局面,笔者认为,应在充分认识大江演变规律的基础上,全面规划,统筹兼顾,对江道进行根本性的治理,以其达到标本兼治,切实提高引水保证率,更好地为工农业用水服务的目的. Since the completion of the Jiangdu hub project in 1976 up to now, the water section of the diversion outlet has been undergoing development and evolution. Two major renovations from 1987 to 1989 and 1993 played a role in ensuring diversion of water. However, In order to reverse this unfavorable situation, the author believes that, on the basis of fully understanding the law of evolution of the great river, it should comprehensively plan and make overall plans to take all factors into consideration, To achieve both the symptoms and the root cause, and effectively improve the water diversion rate, and better service for industrial and agricultural water purposes.
