荆汉生态新水道实施对长江中游航运的影响分析

Analysis on impact of Jinghan Ecological Waterway on navigation in middle reaches of Changjiang River

针对长江干线航道“中梗阻”问题,学界提出了荆汉生态新水道的系统解决方案。通过梳理长江中游地区航运发展条件,从航道、港口、运输安全等方面,分析了荆汉生态新水道的实施对长江中游航运发展的综合影响。研究结果表明:①荆汉生态新水道的建设,在长江中游区域将形成“双通道”的运输格局,促进长江干线航道区段标准统一和区域高等级航道网络化,形成与长江上游地区的便捷通道,大幅提高长江干线大型船舶的通达程度,实现更高层次、更高水平的江海联运、江海直达运输。②新的深水岸线将为区域港口带来良好的发展条件,使高等级航道沿线港口枢纽作用得到增强,但对岳阳港会带来一定的不利影响。③提升区域航道通航的整体安全性,但会增加新老水道交汇区域的通航复杂性,给局部水域带来一定的安全风险。

Aiming at the“middle obstruction”problem in the main channel of the middle Changjiang River,a system solution named Jinghan Ecological Waterway was proposed.Through sorting out the development conditions of waterways and ports in the middle reaches of the Changjiang River,we analyzed the comprehensive impact of the implementation of the Jinghan Ecological Waterway on the development of navigation from the aspects of waterways,ports and transportation safety.The research results show that:①The construction of Jinghan Ecological Waterway will form a pattern of dual channel transportation in the middle reaches area,promote the unification of channel section standardization of the Changjiang River and the networking of regional high-grade channels,forming a convenient channel to the upper reaches of the Changjiang River,greatly improving the accessibility of large ships on the main channel of the Changjiang River,and realizing a higher-level river-to-sea intermodal and direct transportation.②The new deep-water shoreline will bring good development conditions for regional ports,enhance the role of port hubs along new waterways,but it will bring certain adverse effects on Yueyang Port.③Jinghan Ecological Waterway will improve the overall safety of navigation in the midstream region,but it will also increase the complexity of navigation of the intersection area of the new and old waterway,which will bring certain safety risks to local waters.
