A Study On The Evaluation Of Intensive Land Use In Urban Areas Based On BP Artificial Neural Network

Land is the carrier for all economic activities and the basis of human life, with the urban land being the focus of all social and economic activities, the role of urban land is self-evident. During the early stage of urbanization, the economy developed smoothly with enough resourses needed and correct policy, however,various problems emerged in some cities especially thoese middle and small towns afer entering the medium term of urbanization, so, we should seek for the sustainable development of land use through which we can solve thoese problems mentioned and realize the sustainable development of the cities. In terms of intensive utilization of urban land, many scholars have made a considerable achievement concerning the evaluation methods and research structure.after analysing the advantage and disadvantage of previous study results, we set forth a menthod for the evaluation of intensive land use by integrating BP neural networks with ChiBi city in hubei province as an example,.This paper are divided into six chapters:the first chapter mainly discusses the research background, research status, research contents, methods and technical route; The second chapter is for the introduction of traditional theories on intensive land use and BP network; The third chapter is for the present situation of ChiBiShi; The fourth chapter is for the implementation of BP neural networks in the evaluation of intensive land use of ChiBi city; The fifth chapter is for the discussion and analyses about the evaluation results; The sixth chapter is for summarizing this paper and pointing out the problems we should tackle in the future.Some innovative points in this paper are as follows:First, BP artificial neural network is a kind of non-parametric model which is charicterized by its great adaptability,good performance and simplicity, it has the powerful ability to solve the nonlinear problems in the land discipline.Second, through analysing the model selection, model structure design, sample data building and algorithm realization, this paper successfully integrated BP neural networks into the intensive land use research.third, based on BP neural network,this paper constructed a evaluation model for intensive land use from the technical aspect. Finally, from the operational aspect, we made great afforts concerning the practical application and comparative analyses in order to prove the feasibility,reliability and validity of this model,.
