Research On Port Land Use Change Based On CA-BPNN Model

Port construction is an important factor in promoting the development of the port city, port is also an important factor in landscape pattern change. Port rapidly development of land use and ecological landscape pattern of significant changes in the surrounding area, for which research is urgently needed port land-use change, and explore the evolution model law ecotype port, port to provide a scientific basis for land-use planning to ensure sustainable port development.The paper researches on the port land use change, analyzes the evolution of port land drivers, integrated CA model and BPNN model, establish a CA-BPNN port land evolution model, the application of the model in the study of changes in land use in the port to analyze, to provide new ideas and methods for port land evolution studies.In this paper, traditional land use changes in domestic and overseas and port land use change research were reviewed; according to port land characteristics determine the type of land use classification and land ports evolution drivers; integrated cellular automata and BP neural network model, the establishment of the CA-BPNN port land evolution model; with Landsat TM/ETM+satellite remote sensing data and DEM digital elevation data's strength is based on the example of a port area calculations, simulations predict that in 2020 port land use change, and landscape pattern analysis; results showed that CA-BPNN port land evolution model developed in this study can be a good simulation of the future evolution of regional land use and feasibility of the model show; on the model forecast results for future port provide planning, and other issues on the shoreline reserve theory; prediction landscape pattern analysis results can provide a theoretical basis for the future of the port and surrounding areas ecological development strategy ecological construction, corridors and other protected species.
