Influence Of Flow Field And Sediment On The Layout Optimization Of Ecological Port

Ports have always played an important role in the development of the country’s eco nomy.As an important part of the integrated transportation network and international supply chain system,the port not only provides integrated logistics services such as tr ansit,loading and unloading and warehousing,but also integrates productivity such as people flow,goods flow,business flow,capital flow,technology flow and information flow.The basic platform of factor function is the gathering point of goods,capital,t echnology,talents and information.As a junctionof land and sea,the port is a fragile and sensitive area where water ecology and land ecology,human ecology and natural ecology interact.With the rapid development of the economy,there are more and m ore large-scale projects such as coastal development docks and artificial islands in Chi na,and the scale of the project is getting larger and larger.With the continuous expa nsion of port cities and the rapid development of port cities,a series of ecological an d environmental problems brought about by port construction have become increasingly severe.Threewastes have exceeded emission standards,biodiversity has been degraded,alien species invaded,port island heat islands,and port areas.The erosion and siltati on along the coast make the contradiction between the development of human society and the natural ecological environment.Therefore,an ecological port that realizes the concept of port green environmental protection in the whole process of port constructi on and development has emerged as the times require.An ecological port is a port that achieves good economic returns on the basis of m eeting thesustainable development of the ecological environment.The key to ecological port construction is to find a balance between ecological environment and production development,that is,port construction is within the carrying capacity of natural syste ms,and can maintain the sustainable development of the port and surrounding ecologi cal environment.The construction of ecological ports includes various aspects such as ecological cult ure,ecological environment,industrial system and infrastructure.This paper takes the example of port construction in Dalian as the object,and focuses on the construction of Taipingwan Port Area.Through the analysis of flow field and sediment,the impactanalysis method of ecological port layout optimization is proposed.The main content s of this thesis include:1.Quantitative study of the speed of water exchange in the port area by mathemati cal model.2.Through the sediment test study,analyze the distribution of sediment and the sur rounding waters before and after the implementation of different schemes.3.Through the mathematical model of water exchange and sediment analysis,establi sh the relevant impact assessment model,and establish a numerical model and logic a nalysis evaluation model.
