摘　　要：通过疏浚土资源调查及疏浚土利用现状和形势分析,评价了长江口航道疏浚土对不同利用方式的适宜性,提出了“十四五”期疏浚土综合利用的方向和建议。结果表明:(1)长江口航道疏浚土丰富,“十四五”年产量在5800万m3以上,且土质优良、清洁无污染;(2)深水航道南港圆圆沙段和南槽航道九段沙灯船以上段疏浚土适用于筑堤利用和吹填上滩,深水航道北槽中下段及南槽航道九段沙灯船以下段疏浚土可用于滩涂湿地修复和吹填上滩;(3)“十四五”期,建议横沙浅滩利用北槽中下段深水航道疏浚土进行滩涂整治修复,南汇东滩促淤区利用南槽航道疏浚土吹泥上滩储备资源;在破解相关制约因素的基础上,九段沙湿地可利用深水航道北槽中下段和南槽航道九段沙灯船以下段疏浚土实施保育修复,周边涉水工程可利用深水航道南港圆圆沙段和南槽航道九段沙灯船以上段疏浚土开展充填筑堤。Based on the investigation of the amount,quality and utilization situation of dredged soil in Yangtze Estuary navigation channel,this paper evaluates the suitability of dredged soil for different utilization modes,and puts forward suggestions for comprehensive utilization of dredged soil during the 14th Five-year Period.The conclusions are drawn as follows:the annual output of channel dredged soil is estimated to be more than 58 million m~3 in the 14th Five-year Period,and the soil quality is fine and clean.The dredged soil from the South Channel and Yuanyuansha section of Deepwater Channel(SYDC)and the South Passage Channel(SPC)upstream of Jiuduansha Lightship(JL)is suitable for diking and filling,while the dredged soil from the Middle-lower section of North Passage of Deepwater Channel(MNDC)and the SPC downstream of JL can be used for wetland restoration and filling.In the 14th Five-year Period,it’s suggested to use dredged soil of the MNDC to restore Hengsha Shoal,and to use dredged soil of SPC to reserve resources in the siltation promoting project of East Nanhui Shoal.On the basis of solving of relevant constraints,the dredged soil of the MNDC and the SPC downstream of JL can be used for conservation and restoration of Jiuduansha wetland,and the dredged soil of the SYDC and the SPC upstream of JL can be used for embankment construction in the adjacent wading project.
