摘要: The present paper is inclined to bring about its study on the evolutionary trend of the port with ecological bearing capacity of the multiple-functional development modes.For the said purpose,the paper has introduced first of all the system dynamics theory for developing such ports based on the causative loop analysis approach from the point of view of the social economy,human and material resources and the environment-development trends,for such a theory is essentially beneficial for the sustainable development of port ecosystem.In view of the insufficient account of the ecological process and the temporal dynamic features in the current research on the port ecological bearing capacity,we have paid special emphasis on the study of the characteristic features of the port ecosystem,in hoping to keep the ecological supply-demand balance of such ports,we have brought about the supply-demand balance indexes of the ecological bearing capacity in evaluating the ecological bearing capacity in hoping to provide well-investigated and well founded theoretical and applicable facts and proofs.In a case study of a port area of Dalian Port,we have simulated the evolutionary trend of such port ecological bearing capacity from 2015 to 2030 dynamically under the four developmental modes,that is,the natural development mode,the fast economic growth mode,the coordinated development mode,and the resources and environment protection mode with the annual GDP growth rate in addition to the environmental protection investment proportion,the comprehensive energy consumption per throughput,the water consumption per throughput,the COD emission per throughput,SO2 emission per throughput and the solid wastes production per throughput as the control variables.The resuhs of our simulated study indicate that the key bottleneck restraints for improving the aforementioned ecological bearing capacity is the energy consumption.It is just the energy consumption sum-total and the consumption mode that account for the chief factors that are responsible for the port ecological bearing capacity.And,in turn,the best way to achieve the goal of sustainable ecological development of the port is to realize the coordinated development in economy,resources and eco-environment,which can be taken as a theoretical foundation for the future construction of Dalian Port.
