中文摘要: 当前,长江黄金航道面临着长江三峡枢纽和上游水库群联合运行带来的水沙条件新变化,以及防洪、航运、发电、供水、生态等水资源综合利用的新需求,亟待深入认识新水沙条件下航道演变机理及发展趋势,科学评估航道承载力及提升潜力,系统研发水资源综合高效利用目标下的航道整治技术,有效促进航道整治与生态环境保护的协调融合。"长江黄金航道整治技术研究与示范项目"以提高航道通过能力,实现长江航道资源高效利用为目标,凝练了四大关键科学和技术问题:1)水沙变化条件下长江航道演变机理及发展趋势;2)长江重要生物-生境对航道整治工程的响应机制;3)多因素影响下长江航道滩群联动整治方法与技术;4)基于河流完整性的航道整治生境融入及再造技术。结合关键科学问题和技术内涵,提出五大重点研究内容:1)研究长江不同类型河段复杂动力过程与滩槽演变的相互作用机理,预测长江航道演变趋势;2)研究长江生态航道的架构及评价体系;3)评估多功能河流航道承载力及可提升潜力;4)研究多库联调下山区河流卵石滩群联动航道整治技术、防洪-通航协同下中游强冲刷河段航道整治技术、下游复杂多分汊河段航道滩槽调控技术、径潮流河段深水航道协调治理与减淤技术等;5)研究长江航道整治工程的生境融入及再造技术,构建生态友好型航道整治模式。最后,将五大重点研究内容细分为八大前沿研究方向:1)新水沙条件下长江航道演变机理及趋势预测;2)长江生态航道架构及评价方法体系;3)多目标协同下长江黄金航道承载力及提升潜力;4)多库联调下卵石滩群联动航道整治技术;5)防洪-通航协同下强冲刷河段航道整治技术;6)复杂多分汊河段航道滩槽调控技术;7)径潮流河段深水航道协调治理与减淤技术;8)长江典型生态保护段航道整治技术。基于以上内容,初步构建长江航道整治技术研究体系,以期为提高黄金航道通过能力提供理论基础和技术支撑。
Abstract:At present,the ‘Golden Waterway’ of the Yangtze River confronts with new changes of flow and sediment conditions induced by integrated operation of the Three Gorges dam and its upstream reservoir groups.Meanwhile,there are new demands from flood risk management,navigation,electricity generation,water supply and ecology,etc.It is urgent to reveal mechanism of bed morphology evolution and predict its tendency,to develop methods for evaluating waterway capacity and potential,to develop novel waterway technologies satisfying demands of the integrated high efficiency utilization of water resources,and to merge waterway regulation and ecology protection.In the view of actual waterway situation,the project,aiming to enhance the transportation capacity of the Yangtze River and improve the water resources utilization efficiency,has condensed four key scientific issues:1) mechanism of waterway evolution and its tendencyunder variation condition of water and sediment;2) biology and habitat response to waterway regulation;3) theory and technology for shoals groups regulation of the Yangtze River under multi-factors;4) merge and rehabitated technology of waterway regulation based on river completeness.Moreover,combining the connotation of the key scientific issues,five key research contents have been proposed:1) investigate complex dynamic process and interaction between channel and bar for different types reaches,and predict waterway evolution trend;2) build framework and evaluation system for ecologic waterway of the Yangtze River;3) evaluate waterway transportation capacity and its potential for the multi-function river;4) study on technologies for gravel bar groups interlocking in the mountain river under operation of multi-reservoirs,strong erosion in the middle Yangtze River with demands of both flood defense and navigation,channel and bar regulation featuring with multi-channel branches in the lower Yangtze River,coordination regulation and deposition mitigation in the reaches under influence of river and tidal;5) develop merging and rehabitation technology of waterway in the Yangtze River,build framework for ecology-friendly waterway regulation.Finally,eight frontiers have been specified from the five key research contents:1) river evolution mechanism and trend prediction under new water and sediment condition;2) framework and evaluation system for ecological waterway in the Yangtze River;3) transportation capacity and potential of the golden Yangtze River with multi-targets;4) regulation technology of gravel bar groups interlocking under operation of multi-reservoirs;5) regulation technology for strong erosion reaches with demands of both flood defense and navigation;6) regulation technology for channel and bar regulation featuring with multi-channel branches;7) regulation technology for coordination regulation and deposition mitigation under influence of river and tidal;8) regulation technology for typical ecological protection reach in the Yangtze River.Thus,the research system of waterway regulation of the Yangtze River is initially constructed,aiming to provide a theoretical and technical foundation for enhancing the navigation capacity of the ‘Golden Waterway’ of the Yangtze River.
