Research On The Multi-model Construction For Coastal Reclamation Scale And Control

In view of the coastal reclamation is in the rapid development process,herecomes the reality problem that the scientific basis and the effective,quantitativecontrol standards of reclamation scale control is lacking. This paper established theoverall research route of demand and supply evaluation and the comprehensiveoverall balance of reclamation, from the research on method and paradigmconstruction of reclamation scale by reference to the similar subjects ideas. Firstly,mathematical statistics method used to make review and assessment of the overseasrepresentative reclamation area, summarize demand index, benefit index, and changelaw on historical accumulation of reclamation scale. Secondly, maximum supplyability of the general area of coastal reclamation under practical conditions wasevaluated based on the state-space method. The abstract mathematics formula forsupply scale computing was given, and a three-dimensional evaluation model ofvisual expression constructed. Then, we made comprehensive balance of supply anddemand analysis the by system dynamics method to establish a evaluation systemmodel that is comprehensive, systematic, objective, quantifiable, and easyreclamationfor scale under the guide of sustainable development concept of reclamation area.Taking the Binhai New Area reclamation of Tianjin for examples, using the model, wealso validated prediction on the future dynamic development. In addition, this papersummarized the main influence factors of the reclamation scale, combed the relevantevaluation index system., and empirical compared of many schemes of thereclamation processunder different development conditions. Finally, through the studyand analysis on determination of the land reclamation scale, this paper proposed ninerecommendations of control standards and planning policys form three aspects ofselection, total land controling, proportional controling of reclamation area.
