长江上海段疏浚土有益利用的框架性建议

摘要:
疏浚土是水利水运工程衍生的一种宝贵资源。在长江上海段,针对上游来沙量持续减少、河口砂土资源日趋紧缺、海洋倾倒区逐渐受控等新形势,开展港口航道疏浚土的有益利用是涉水部门的共同期望。依据工程现场调查资料,分析了长江上海段疏浚土有益利用的现状和存在的主要问题,结合新形势和新要求提出了疏浚土有益利用的框架性建议。研究分析表明,近10年来,长江上海段疏浚土有益利用实现了从无到有的历史性跨越,用于吹填造地的长江口深水航道疏浚土数量较为可观。但存在疏浚土利用方式单一、利用率总体偏低、相关体制机制尚未完善等诸多现实问题。为进一步提高长江上海段疏浚土的有益利用水平,提出框架性建议如下:加紧疏浚土有益利用关键技术研发,加快转变疏浚土资源化利用方式,以及加大疏浚土有益利用体制机制创新力度等

Abstract:
The dredged material is a valuable resource derived from hydraulic engineering and waterway engineering. At the Shanghai reach of the Yangtze River, beneficial use of the dredged material from port and navigation channel is the common expectation of water departments under the new situation of declining sediment discharge from upstream, shortage of sand resources and limitation of ocean dumping sites in the estuary. Based on the investigated data collected from engineering field, beneficial use of the dredged material at the Shanghai reach of the Yangtze River has achieved a historic leap from nothing to something in recent 10 years, and the quantity of the dredged material from the Yangtze estuary deepwater navigation channel used for land reclamation is considerable. But at the same time, there are lots of realistic problems such as simple use of the dredged material, low ratio of utilization, and imperfect system. For the purpose of further improving the utilization level of the dredged material at the Shanghai reach of the Yangtze River, some framework suggestions are as follows: strengthening the research and development of key techniques, speeding up the transformation of utilization mode of the dredged material, and increasing the innovation of related systems and mechanism.
Key words:  dredged material  beneficial use of the dredged material  Shanghai reach of the Yangtze River  framework suggestions
